"Lead is a neurotoxin; it causes premature deaths and lifelong negative effects. It’s said “there is no safe level of lead exposure” — as far as we know, any lead causes damage, and it just gets worse the more exposure there is.

After a 20-year, worldwide campaign, in 2021 Algeria became the final country to end leaded gasoline in cars — something the US phased out in 1996. That should make a huge difference to environmental lead levels. But lots of sources remain, from car batteries to ceramics...

Bangladesh phased out leaded gasoline in the 1990s. But high blood lead levels have remained. Why? When researchers Stephen Luby and Jenny Forsyth, doing work in rural Bangladesh, tried to isolate the source, it turned out to be a surprising one: lead-adulterated turmeric.

Turmeric, a spice in common use for cooking in South Asia and beyond, is yellow, and adding a pigment made of lead chromate makes for bright, vibrant colors — and better sales. Buyers of the adulterated turmeric were slowly being poisoned...

But there’s also good news: A recent paper studying lead in turmeric in Bangladesh found that researchers and the Bangladeshi government appear to have driven lead out of the turmeric business in Bangladesh.

How Bangladesh got serious about lead poisoning

The researchers who’d isolated turmeric as the primary cause of high blood lead levels —working for the nonprofit International Center for Diarrheal Disease Research, Bangladesh — went to meet with government officials. They collected samples nationwide and published a 2019 follow-up paper on the extent of the problem. Bangladesh’s Food Safety Authority got involved.

They settled on a two-part approach, starting with an education campaign to warn people about the dangers of lead. Once people had been warned that lead adulteration was illegal, they followed up with raids to analyze turmeric and fine sellers who were selling adulterated products.

They posted tens of thousands of fliers informing people about the risks of lead. They got coverage in the news. And then they swept through the markets with X-ray fluorescence analyzers, which detect lead. They seized contaminated products and fined sellers.

According to the study released earlier this month, this worked spectacularly well. “The proportion of market turmeric samples containing detectable lead decreased from 47 percent pre-intervention in 2019 to 0 percent in 2021,” the study found. And the vanishing of lead from turmeric had an immediate and dramatic effect on blood lead levels in the affected populations, too: “Blood lead levels dropped a median of 30 percent.”

The researchers who helped make that result happen are gearing up for similar campaigns in other areas where spices are adulterated.

The power of problem-solving

...When the Food Safety Authority showed up at the market and started issuing fines for lead adulteration, it stopped being a savvy business move to add lead. Purchasers who were accustomed to unnatural lead-colored turmeric learned how to recognize non-adulterated turmeric. And so lead went from ubiquitous to nearly nonexistent in the space of just a few years.

That’s a better world for everyone, from turmeric wholesalers to vulnerable kids — all purchased at a shockingly low price. The paper published this month concludes, “with credible information, appropriate technology, and good enough governance, the adulteration of spices can be stopped.”

There’s still a lot more to be done. India, like Bangladesh, has widespread adulteration of turmeric. And safety testing will have to remain vigilant to prevent lead in Bangladesh from creeping back into the spice supply.

But for all those caveats, it’s rare to see such fast, decisive action on a major health problem — and impressive to see it immediately rewarded with such a dramatic improvement in blood lead levels and health outcomes. It’s a reminder that things can change, and can change very quickly, as long as people care, and as long as they act."

The new tool in the art of spotting forgeries: Artificial Intelligence

Instead of obsessing over materials, the new technique takes a hard look at the picture itself – specifically, the thousands of tiny individual strokes that compose it

In late March, a judge in Wiesbaden, Germany, found herself playing the uncomfortable role of art critic. On trial before her were two men accused of forging paintings by artists including Kazimir Malevich and Wassily Kandinsky, whose angular, abstract compositions can now go for eight-figure prices. The case had been in progress for three and a half years and was seen by many as a test. A successful prosecution could help end an epidemic of forgeries – so-called miracle pictures that appear from nowhere – that have been plaguing the market in avant-garde Russian art.

But as the trial reached its climax, it disintegrated into farce. One witness, arguably the world’s leading Malevich authority, argued that the paintings were unquestionably fakes. Another witness, whose credentials were equally impeccable, swore that they were authentic. In the end, the forgery indictments had to be dropped; the accused were convicted only on minor charges.

The judge was unimpressed. “Ask 10 different art historians the same question and you get 10 different answers,” she told the New York Times. Adding a touch of bleak comedy to proceedings, it emerged that the warring experts were at the wrong end of a bad divorce.

It isn’t a comforting time for art historians. Weeks earlier, in January, the Museum of Fine Arts in Ghent, Belgium, was forced to pull 24 works supposedly by many of the same Russian artists – Kandinsky, Malevich, Rodcheko, Filonov – after the Art Newspaper published an exposé arguing they were all forged. Just days before, there was uproar when 21 paintings shown at a Modigliani exhibition in Genoa, Italy, were confiscated and labeled as fakes. Works that had been valued at millions of dollars were abruptly deemed worthless.

The market in old masters is also jittery after an alarming series of scandals – the greatest of which was that paintings handled by the respected collector Giuliano Ruffini were suspect. A Cranach, a Parmigiano, and a Frans Hals were all found to be forged; institutions including the Louvre had been fooled. The auction house Sotheby’s was forced to refund $10m for the Hals alone. Many experts are now reluctant to offer an opinion, in case they’re sued – which, of course, only intensifies the problem.

Adding fuel to the fire is another development: Wary of being caught, more and more forgers are copying works from the early to mid-20th century. It’s much easier to acquire authentic materials, for one thing, and modern paintings have rocketed in value in recent years.

For many in the industry, it is starting to look like a crisis. Little wonder that galleries and auction houses, desperate to protect themselves, have gone CSI. X-ray fluorescence can detect paint and pigment type; infrared reflectography and Raman spectroscopy can peer into a work’s inner layers and detect whether its very component molecules are authentic. Testing the chemistry of a flake of paint less than a millimeter wide can disclose deep secrets about where and, crucially, when it was made.

“It’s an arms race,” says Jennifer Mass, an authentication expert who runs the Delaware-based firm Scientific Analysis of Fine and Decorative Art. “Them against us.”

But what if you didn’t need to go to all that trouble? What if the forger’s handwriting was staring you in the face, if only you could see it? That’s the hope of researchers at Rutgers University in New Jersey, who have pioneered a method that promises to turn art authentication on its head.

Instead of subjecting works to lengthy and hugely expensive materials analysis, hoping a forger has made a tiny slip – a stray fiber, varnish made using ingredients that wouldn’t have been available in 16th-century Venice – the new technique is so powerful that it doesn’t even need access to the original work: A digital photograph will do. Even more striking, this method is aided by artificial intelligence. A technology whose previous contributions to art history have consisted of some bizarre sub–Salvador Dalís might soon be able to make the tweed-wearing art valuers look like amateurs.

At least that’s the theory, says Ahmed Elgammal, PhD, whose team at Rutgers has developed the new process, which was made public late last year. “It is still very much under development; we are working all the time. But we think it will be a hugely valuable addition to the arsenal.”

That theory is certainly intriguing. Instead of obsessing over materials, the new technique takes a hard look at the picture itself: Specifically, the thousands of tiny individual strokes that compose it.

Every single gesture – shape, curvature, the velocity with which a brush- or pencil-stroke is applied – reveals something about the artist who made it. Together, they form a telltale fingerprint. Analyze enough works and build up a database, and the idea is that you can find every artist’s fingerprint. Add in a work you’re unsure about, and you’ll be able to tell in minutes whether it’s really a Matisse or if it was completed in a garage in Los Angeles last week. You wouldn’t even need the whole work; an image of one brushstroke could give the game away.

“Strokes capture unintentional process,” explains Elgammal. “The artist is focused on composition, physical movement, brushes – all those things. But the stroke is the telltale sign.”

The paper Elgammal and his colleagues November 13, 2017 examined 300 authentic drawings by Picasso, Matisse, Egon Schiele, and a number of other artists and broke them down into more than 80,000 strokes. Machine-learning techniques refined the data set for each artist; forgers were then commissioned to produce a batch of fakes. To put the algorithm though its paces, the forgeries were fed into the system. When analyzing individual strokes, it was over 70% accurate; when whole drawings were examined, the success rate increased to over 80% . (The researchers claim 100% accuracy “in most settings.”)

The researchers are so confident that they included images of originals and fakes alongside each other in the published paper, daring so-called experts to make up their own minds. (Reader, I scored dismally.) One of Elgammal’s colleagues, Dutch painting conservator Milko den Leeuw, compares it to the way we recognize family members: They look similar, but we’re just not sure why. “Take identical twins,” he says. “Outsiders can’t separate them, but the parents can. How does that work? It’s the same with a work of art. Why do I recognize that this is a Picasso and that isn’t?”

The idea of fingerprinting artists via their strokes actually dates back to the 1950s and a technique developed by Dutch art historian Maurits Michel van Dantzig. Van Dantzig called his approach “pictology”, arguing that because every work of art is a product of the human hand, and every hand is different, it should be possible to identify authorship using these telltale strokes.

The problem, though, was that there was too much data. Even a simple drawing contains hundreds or even thousands of strokes, all of which needed to be examined by the human eye and catalogued. Multiply that by every work, and you see how impractical it was.

“It just wasn’t possible to test it,” says den Leeuw, who first became aware of pictology as a student. “I saw many attempts, but mostly it ended in ideas that would never be.”

But can AI now do what humans failed to, and give an art historian’s trained eye some sort of scientific basis? “Exactly,” says den Leeuw. “Very often it’s a gut feeling. We’re trying to unpick the mystery.”

Though Mass says she’s unlikely to throw out her fluorescence gun just yet, she admits to being impressed. “A lot of people in the field are excited by AI It’s not a magic bullet, but it’ll be another tool. And it’s really valuable when you’re dealing with a sophisticated forger who’s got everything else right – paint, paper, filler, all the materials.”

There are issues. So far, the system has been tested mainly on drawings from a handful of artists and a brief time period. Paintings, which generally contain thousands more strokes, are a tougher challenge; older paintings, which might contain numerous layers of restoration or overpainting, are tougher still. “It’s challenging, but it doesn’t mean we can’t do it,” Elgammal says. “I’m confident.”

What about style, though, particularly where an artist changes over time? Think of Picasso’s wildly varying periods – blue, African, cubist, classical – or how in the 1920s Malevich abandoned the elemental abstraction of his black squares for figurative portraits that could almost have been painted by Cézanne (pressure from Stalin was partly responsible).

Another expert, Charles R Johnson, who teaches computational art history at Cornell, is less persuaded – not so much by the AI as by the assumptions that lie behind it. “A big problem is that strokes are rarely individualized,” he says. “Overlap is difficult to unravel. Plus, one must understand the artist’s style changes over their career in order to make a judgment.”

In addition, Johnson argues, many artist’s brushwork is essentially invisible, making it impossible to unpick; it might be better to focus computer analysis on assessing canvases or paper, which can be more rigorously verified. “I remain quite skeptical,” he says.

Elgammal and den Leeuw concede there’s a way to go. Currently they’re working on impressionist paintings – infinitely more complex than Schiele and Picasso line drawings – and hope to publish the results next year. Even with the drawings, the machine can’t yet be left to learn on its own; often the algorithms require human tweaking to make sure the right features are being examined. Artists whose output isn’t large enough to create a reliable data set are also a challenge.

Asking Elgammal if he’s worried about being sued. He laughs, slightly nervously. “That’s something I think about.”

It’s a reasonable question, particularly pressing given the number of fakes that are circulating: What if your database accidentally becomes contaminated? Many people argue that the art market is hopelessly corrupt – so much so that some economists doubt whether calling it a “market” is even fair. Could the algorithm become skewed and go rogue?

“It’s like any system,” Mass agrees. “Garbage in, garbage out.”

Does she think that’s a possibility? How many fakes are out there? “Put it this way,” Mass says, “when I go into auction houses – maybe not the big ones, but smaller, local ones – I think ‘buyer beware.’ It might be between 50 and 70% .”

Rival solutions are coming down the road. Some have proposed using blockchain technology to guarantee provenance – the history of who has owned a work. Others have called for much greater transparency. Everyone agrees that the system is broken; some kind of fix is urgent.

Of course, there are big philosophical questions here. When someone goes to the effort of finding exactly the right 17th-century canvas, dons an antique smock, and paints a near-flawless Franz Hals, it should perhaps make us reconsider what we mean by the words “real” or “fake”, let alone the title of “artist”. Yet the irony is inescapable. It is hard to think of something more human than art, the definition of our self-expression as a species. But when it comes down to it, humans aren’t actually that good at separating forged and authentic in a painting that has all the hallmarks of, say, a Caravaggio but is merely a stunt double. Relying on our eyes, we simply can’t tell one twin from the other. We might even ask: Why do we care?

Forget cars that pilot themselves or Alexa teaching herself to sound less like the robot she is – AI seems to understand the secrets of artistic genius better than we do ourselves.

The irony is that, while machines might not yet might be able to make good art, they are getting eerily good at appreciating it. “Yes, it’s true,” he says thoughtfully. “When it comes to very complex combinations of things, humans are really not so good.” He laughs. “We make too many mistakes.”

Colour Seminar

Part 1 and 2

In this Colour Seminar with Sylvia Shortall I learned a lot about colour and how important it is in art and the world around us.

The most interesting information I learned in the first part of the seminar was when Sylvia taught us about the Pantone Colour matching system.

The Pantone colour matching system is a standardised colour matching system, which is used around the world by artists and designers. It is used to access colour trends, communicate colour choices and control consistency if colours across every imaginable surface, texture material and finish. What I think is the most interesting thing about Pantone is that they have a tradition where they announce the colour of the year. This tradition started in the year 2000 where they announced the colour of the year as Cerulean, all the way to 2023 where they decided the colour of the year is Viva Magenta. To decide the colour of the year Pantone takes into consideration all aspects of society, fashion, marketing, social media and politics and decide which colour best represents the year.

Part 2 was my favorite part of the seminar. Sylvia spoke about the rivalry between Anish Kapoor and Stuart Semple. I found this to be very intriguing.

Vantablack is the worlds “blackest black”. It was invented by Ben Jensen, chief technology officer for a company called NanoSystems. Instead of reflecting light this incredible black coating absorbs 99.96% of light, making whatever it is painted on look like a black void. Anish Kapoor, a British sculptor purchased the exclusive rights to the artistic use of Vantablack, and Stuart Semple and the rest of the art community did not appreciate this.

As payback Stuart Semple created the colour “the pinkest pink” and allowed everyone to use and purchase it excluding Anish Kapoor. Semple’s pink is an intense ultra-fluorescent pink which directly contrasts with Kapoor’s Vantablack. The pink shade is available to buy for all artists on Semple’s website for no profit, except for Anish Kapoor who is legally banned from purchasing it.

When you but this pigment you have to sign saying you are not Anish Kapoor, you are not in association with Anish Kapoor and you are not buying the pigment on behalf of Anish Kapoor. However in 2016 Kapoor got his hands on the pigment and posted this picture to his Instagram captioned “up your #pink”

The colour seminar made me realise how little colour I have used in my disrupt project so far, I want to incorporate more going forward.

Light-fast? My pigment is a fugitive and ran away with the sun!

Okay, okay, you're about to be subjected to one of my favourite topics, so if you have no interest in traditional art and why some stuff fades away (quite literally) then move along.

But if you're like me, and you want to know more about pigments vs dyes and why your pink thing has over time become a white thing, keep reading…

So, my interest, aka my dive into the rabbit hole that is lightfastness, started way back when I made a friend a bright pink thing (cheap student grade acrylic paint on canvas board) , they hung it up in their window, and it slowly turned into a white thing.

Gasp! Shock! Horror!

No really, I was slightly traumatized, simply because I was about to start selling my artwork and if it was going to fade away in the space of a year odd, then I was going to have a big problem. I mean, you can't sell art and then tell people they must keep it in a dark place and only observe it under moonlight. Well okay you probably could if you marketed it right, but I'm terrible at marketing and the idea of someone coming back to complain about the art disappearing gives me anxiety.

So I went on a hunt to find out WHY.

So let's talk about pigments vs dyes and what fugitive pigments are, and why artist grade is so much more expensive than student grade.

What's the difference between pigments and dyes?

Think of paint made from pigments as a suspension, finely ground up particles are suspended in a medium, much like mixing sand into water. If you let a sandy water mix sit for long enough the sand particles will sink to the bottom and separate from the water. Pigment based paint sits on the surface of your canvas or paper (yep even watercolours, the paper gets wet, but when it dries the pigments are sitting on the surface, they haven't sunk in and bonded with the paper). Pigment based paint is more inclined to be opaque.

Paint made from dyes are a solution, very very finely ground particles are dissolved into a medium and change their chemical makeup, you can let them sit as long as you like and they won't separate. Dyes sink into the surface of the paper or canvas. Dyes are naturally transparent. Dyes are used for fabric precisely because they sink into the surface and bond with it.

So, those fugitive pigments huh?

I'll start with the kicker, dyes, by their very nature, are fugitive. Let me explain that a bit more - dyes are a solution, they have chemically bonded with the medium and because of this chemical change they are much more vulnerable to UV light, to the point they can completely disappear. Alcohol markers are a prime example of this. This is also why clothing fades over time.

Any fluorescent colour is fugitive. Don't ask me why, they just are.

So what about pigments? Well, if you mix them with oil, pretty much all the pigments will manage to stick around, oil creates a protective coating that shields the pigments from UV light.

Not so with other mediums though, so some pigments will fade over time. As paint companies have become aware of this, they have tried to find alternative pigments that are light-fast and you will find a light-fast rating on good brands of paint.

The white factor.

White tends to be opaque and is very light-fast, it's usually PW6 pigment for titanium white and PW5 for zinc white, which is also known as the mixing white and is supposedly less opaque - personally I can't tell the difference.

So, white, all good, gonna use white which is light-fast and this tube of red which is also listed as light-fast and make pink, no worries right? Wrong.

Mixing white into other pigments can make them less light-fast. Why???? I hear you scream.

It's to do with (someone correct me if I'm wrong but this is my understanding) the fact white reflects light, so as soon as you mix another pigment into white, not only is the concentration of the pigment reduced, it's also at the mercy of all that extra light. Some pigments are naturally very light-fast anyway and being mixed with white won't be much of an issue.

Avoiding the known fugitive pigments is a good start to ensuring your artwork is going to stick around for the long haul, of course painting in oils is more of a guarantee but not everyone can be bothered with the mess.

So, artist grade vs student grade?

In general artist grade paint will have a light-fast rating, list the pigments used AND most importantly they will contain much more pigment and better quality pigments than cheaper paints. More pigment means stronger more vibrant colours, you need less paint to cover a surface, there are no fillers like chalk to make the paint opaque and the quality of the pigments is higher. Basically when you buy artist grade paint you are paying for the pigments used, you're more likely to find single pigment paints and the pigments are more likely to be light-fast.

Of course oil paint can pretty much ignore this, buy whatever works for you, it's not going to matter much.

What about student grade? Well, student grade from a reputable brand may still give you a list of pigments and a light-fast rating, you can feel pretty assured that the paint will perform as required, but the pigments will be cheaper and less concentrated. If, like me, you have found yourself utterly annoyed you can't get a vibrant enough look from your student grade paint no matter how much you apply, then this is why, it simply doesn't have the same amount of pigment as the artist grade in the same brand does. While the artist grade is more expensive, my personal findings with watercolours are that I use much less of it because it is more pigmented, so it works out more cost effective in the long run.

Student grade will often substitute an original pigment for a 'hue', like 'cadmium red hue' which is a replication of the colour and doesn't actually contain the cadmium red pigment. So you get a lower cost pigment in a lesser concentration.

Student grade paint generally won't be as concerned with using light-fast pigments, so you're more likely to find less permanent pigments and also pigment mixtures rather than pure single pigment paints.

What's the difference between single pigment and mixed pigment? Glad you asked. It's the mud factor, we've all mixed paints together and come out with a sludgy grey muddy colour right? Mixed pigment paints when they contain multiple pigments are more likely to give you dull muddy colour when you mix them with other paints, simply because mixing complimentary colours together will give you a neutral grey. (Stares hatefully at reeves watercolours, my first experience with mud production and chalkiness)

Single pigment paints are easier to mix vibrant colours with.

What about student grade, or ungraded paint from non recognized brands? Well, generally they make up their own names for the colours, they give you no pigment or light-fast rating (though many claim to be light-fast, they show no actual ratings and can't be trusted) and they can often contain dyes as well as fugitive pigments, because they are cheaper to use. They will contain a lot of fillers and less pigments, and can be harder and more frustrating to use. It's not always the case of course, but in general you get what you pay for.

Finally, designer mediums vs art mediums.

Or - was never intended to last vs meant to be hung on a wall.

Some currently popular and commonly used mediums were never intended for preservation. They were created for design, be it architecture, fashion design, magazine illustrations or other things that were made to be photographed and then reproduced in print.

Prime examples of this are alcohol markers and gouache. They were never ever intended to be light-fast, they were made for quick execution and reproduction, the original was often just thrown out.

Gouache, because it dries fast and is matte makes it perfect for both quick turnaround illustrations and reproduction. The matte surface makes photography easy without any worries about reflected light messing up the image. It was used extensively in the magazine and printed periodical industry.

Alcohol markers were more aimed at the design industry.

Gouache, by it's very design tends to still be very inclined to use fugitive pigments, Windsor & Newton do have some with high light-fast ratings, but you have to read the labels carefully and if you use the paint as a wash it's still going to say goodbye faster than it should (it's the white factor again, this time it's the white of the paper).

Alcohol markers, as I've said before, are dye based, and are highly fugitive. (Do I get mad when people sell original art done in alcohol markers, yeah, a little bit, I feel bad for the person buying it who presumably wants to put it on the wall and it IS going to fade away. I don't see anything wrong with selling the artwork, markers have their own charm and the effects are quite unique, but you should at least warn people that it's fugitive)

Most calligraphy inks designed to go inside pens are dye based and will fade. (Gel writing pens too, even in closed books that will fade drastically, ask me how I know!) (Pigment based ones tend to clog so are reserved for dip pens and brushes, and are usually mixed with shellac to make them waterproof. )

Don't be put off using these mediums, they are great fun to play around with, just be aware that they are not designed to be exposed to light for long periods of time are best for reproduction as prints.

Can you enhance the lightfastness of a painting?

Yep, put it behind glass (perspex is even better?). I think it's possible to find UV resistant varnish too, but don't quote me on that, I haven't seen any myself. I don't think this is a reliable method for dye based art though sadly, while watercolours behind glass will last longer, some dyes can fade away even without light on them (see the gel pen experience)

Can you do your own lightfastness test on your mediums?

Sure can, as long as you have a control swatches kept in a dark place, you can put swatches in direct sunlight and compare them to the ones you kept in the dark to see how much they have faded and how long it took. Some will show no signs of fade even after a year of direct sunlight, some might disappear completely, it will depend on the pigments.

So there you have it, the lowdown on the difference between pigments and dyes, why your medium of choice makes a difference to how long your artwork will last and what makes artist grade what it is.

Technique using light and artificial intelligence is effective in selecting immature soybean seeds

- By Luciana Constantino , Agência FAPESP -

Historically based on tradition and experience, the decision-making process in agriculture has been transformed in recent years by technological innovations that scale up production and provide solutions to the challenges posed by pests, natural limitations on arable land and the effects of climate change.

Brazilian researchers have developed a technique to help select seeds of soybeans and other legumes in accordance with maturity stages, assuring physiological quality without destroying samples.

The scientists used light and artificial intelligence (AI) to show that chlorophyll fluorescence is an effective and reliable indicator of soybean seed maturity. They validated the results by means of machine learning algorithms. The novel technique can be used to classify commercial seeds.

The greener and less mature the seeds, the less vigor and germinating power they have, so that their quality is lower. As a result, the market value of soybean seed lots with more than 8% green seeds is reduced and they cannot be exported. Green seeds also produce less oil, with higher acidity and higher refining costs.

Manual seed quality analysis is required by law in Brazil. It must be performed by a technician accredited with the Ministry of Agriculture and entails visual separation based on color. Green seeds are discarded and destroyed, forming waste.

“I consider this study a milestone. No studies in the literature to date have addressed the possibility of separating seed stages based on chlorophyll fluorescence. The method can be used for other legumes besides soybeans. It’s a major advance in scientific knowledge,” said Thiago Barbosa Batista, first author of an article on the study published in the journal Frontiers in Plant Science.

The research was part of Batista’s PhD thesis, developed with FAPESP’s support. His thesis advisor was Edvaldo Aparecido Amaral da Silva, a professor at São Paulo State University's School of Agricultural Sciences (FCA-UNESP) in Botucatu, and last author of the article.

“Phenotyping various kinds of seed was the main reason for starting our thematic group. We focused on chlorophyll retention and its association with low quality, and this in turn led to the need to analyze the stages of seed development. The results of this study enhance the reliability of maturity characterization when seeds are similar shades of green, especially in nearby stages,” said Amaral da Silva, who leads a project on the “green seed problem”.

The study was conducted in partnership with Clíssia Barboza da Silva, a researcher at the Radiobiology and Environment Laboratory belonging to the University of São Paulo's Center for Nuclear Energy in Agriculture (CENA-USP). Barboza da Silva is also supported by FAPESP via three projects (17/15220-7, 18/03802-4, and 18/01774-3).

“This technique avoids destroying seeds, which are classified automatically by the AI algorithm. We currently analyze samples, but it could be done seed by seed in future,” she said.

For some years Barboza da Silva has analyzed seeds using light-based technologies such as autofluorescence spectral imaging. In September 2021, a study led by her showed that images based on autofluorescence could be used to detect changes in the optical properties of soybean seed tissue and consistently distinguish between seeds with high and low vigor. An article on the study was published in Scientific Reports.

Maturity in images

The researchers sowed soybean seeds in pots, maintaining relative air humidity at 65% and average air temperature at 24.2 °C. Pods were collected manually during the maturation phase, and the seeds were classified by reproductive stage, as R7.1 (start of maturation), R7.2 (mass maturity), R7.3 (seed disconnected from mother plant), R8 (harvest point), or R9 (final maturity).

Physical parameters, germination, vigor and pigment dynamics were analyzed for seeds collected at different stages of maturation.

High-resolution autofluorescence spectral images (2192x2192 pixels) were captured using a VideometerLab4 system with light-emitting diodes (LEDs) at different excitation wavelengths combined with long-pass optical filters.

Autofluorescence signals were extracted from images captured at different excitation/emission combinations, but the researchers concluded that the combinations 660/700 nanometers (nm) and 405/600 nm performed fastest and most accurately in identifying the different stages of seed maturation.

Chlorophyll is highly fluorescent. It emits light when exposed to radiation at specific wavelengths because it does not use all the energy from the light and “loses” part of it via fluorescence. This “surplus” is captured by the equipment, which converts it into an electrical signal, generating an image with varying shades of gray as well as white and black. The lighter the area, the higher the chlorophyll content, showing that the seed is less mature.

Mature seeds normally retain chlorophyll as a source of energy while the nutrients required for development of the young plant (lipids, proteins and carbohydrates) are being stored. After fulfilling this function, the chlorophyll degrades, and the less chlorophyll remains, the more advanced the seed is in the maturation process, with more nutrients and better quality.

The “green seed problem” refers to chlorophyll retention in mature seeds and is associated with lower oil and seed quality. It can be caused by frost but is exacerbated by the high temperatures and water stress brought by climate change in recent years.

The article “A reliable method to recognize soybean seed maturation stages based on autofluorescence-spectral Imaging combined with machine learning algorithms” is at: www.frontiersin.org/articles/10.3389/fpls.2022.914287/full.

Choosing the Right Color Measurement Device: Portable VS Benchtop Spectrophotometers (Benchtop Transmittance Spectrophotometer)

There are many different brands of color spectrophotometers on the market, and even within the same brand, there are multiple products available. The handheld and desktop types are the most popular categories, but what are the differences between these two types? Portable Colorimeters – also known as Portable spectrophotometers Can directly read data and connect to a computer through software: Small size, convenient to carry, high accuracy, and moderate price. Easy to operate, even ordinary personnel can easily handle it. Desktop Colorimeters – also known as Benchtop Transmittance Spectrophotometer: Equipped with a reading window, used with color matching software when connected to a computer, has high accuracy color matching function, large size, stable function, and high price. As we all know, Benchtop Transmittance Spectrophotometer are more accurate and consistent than portable devices. When using strict tolerances or setting color specifications, desktop devices are usually the preferred choice. Professionals working with brand colors or components of their products must match each other in the final assembly process, using desktop devices to set specifications, formulas, and quality control. On the other hand, portable colorimeters are more suitable for spot checking product quality as they are easy to carry around. Portable VS Benchtop Spectrophotometers: If you want to measure liquids such as orange juice, laundry detergent, or shampoo, please choose a Benchtop Transmittance Spectrophotometer; Benchtop Transmittance Spectrophotometer are also the preferred choice for setting color formulas. They are suitable for controlling fluorescence and fluorescent whitening agents in paper, textiles, plastics, pigments, and paints. Using automatic instrument settings eliminates the possibility of speculation and errors during instrument configuration. Portable colorimeters are convenient to carry around and can be used for quality control in the laboratory. They are widely used in industries such as plastics, printing, and metal spraying for quality inspection and monitoring. They are compact, handheld, simple, and inexpensive instruments, but still effective for specific purposes. In a Benchtop Transmittance Spectrophotometers, a specific light source (such as A or D65) illuminates the object. The reflected light passes through primary filters: red, green, and blue, which simulate the spectral sensitivity curve and reach the detector, where it provides a response proportional to the three-stimulus values. Therefore, colorimeters provide information about the amount of red, green, and blue light reflected by the object. This color information is useful for color evaluation that does not require complexity or accuracy. For example, colorimeters are very useful in production environments where measuring color differences between products and standards, or between production batches, is important. It can also be compared to color charts for evaluation purposes. Benchtop Transmittance Spectrophotometers are more complex and accurate color evaluation devices than colorimeters. They are used for color quality control in processes that require higher accuracy, such as research labs, color formulas in paint and cosmetics companies, etc. Spectrophotometers can be handheld, with a compact and user-friendly design, suitable for industrial environments on the product line. Or they can be desktop spectrophotometers that require a more comprehensive understanding of the user, but offer greater versatility. Generally, handheld spectrophotometers or handheld measurements are used to measure opaque solid objects, while desktop spectrophotometers can be used to measure the color of opaque solids, semi-transparent solids, and liquids. DSCD-910_Benchtop Spectrophotometer (Transmittance) Benchtop Transmittance Spectrophotometers used for color evaluation measure the reflection or transmission radiation of the entire visible spectrum. To do this, a monochromatic radiation is used to illuminate the sample or object (spectrophotometers have monochromators, filters, or prisms that can distinguish wavelengths), and the amount of reflected or transmitted radiation is recorded. Benchtop Transmittance Spectrophotometers are very common instruments used in color measurement. They are widely used in areas such as color evaluation, color control, color matching, and material composition analysis. As a precision instrument for color measurement, its working principle is to use a spectrophotometer to display the ratio of the spectral composition and diffraction curve of a graph and calculate the measured value accordingly. It automatically records the data measured by the spectrophotometer, and then calculates the measurement result automatically. In addition to the microprocessor and related circuits, the spectrophotometer has four main components: light source, integrating sphere, grating (monochromator), and photodetector. Different models of spectrophotometers have different components, which affect the accuracy of the measurement results. Spectrophotometers, as precise measurement instruments, have a unique measurement method that is not complicated. It mainly consists of four steps: 1. Calibration In actual use, calibration is required to ensure accuracy. There are two calibration methods: one is to use standard samples to calibrate, and the other is to use raw data from the light source for calibration. Calibration can ensure that the spectrophotometer has consistent standards under different test conditions. 2. Sampling Before testing, a sample of the object needs to be taken. This step usually requires taking a small piece from the surface of the object while avoiding contamination and damage to the sample surface as much as possible. 3. Measurement Before measuring, the sample needs to be fixed on the spectrophotometer according to the requirements. Then, using the instrument’s built-in operating interface, input the required measurement items and illuminate the sample with the light source. After a certain test time, the test data is recorded. 4. Analysis and Results After obtaining the measurement data, it is necessary to perform analysis and statistics and further processing based on the analysis results. For example, by calculating the color difference value, the level of color difference from the standard sample can be determined, thereby determining the color accuracy. As a highly precise color inspection device, spectrophotometers can detect the “reflectivity curve” of each color point, which cannot be achieved by many simple color difference meters. In addition, spectrophotometers can simulate multiple light sources, allowing you to perform color difference calibration work in the designated light source box specified by the inspection company.
