#CONTAMINATION

[reasonsforhope]

"A 9th grader from Snellville, Georgia, has won the 3M Young Scientist Challenge, after inventing a handheld device designed to detect pesticide residues on produce.

Sirish Subash set himself apart with his AI-based sensor to win the grand prize of $25,000 cash and the prestigious title of “America’s Top Young Scientist.”

Like most inventors, Sirish was intrigued with curiosity and a simple question. His mother always insisted that he wash the fruit before eating it, and the boy wondered if the preventative action actually did any good.

He learned that 70% of produce items contain pesticide residues that are linked to possible health problems like cancer and Alzheimer’s—and washing only removes part of the contamination.

“If we could detect them, we could avoid consuming them, and reduce the risk of those health issues.”

His device, called PestiSCAND, employs spectrophotometry, which involves measuring the light that is reflected off the surface of fruits and vegetables. In his experiments he tested over 12,000 samples of apples, spinach, strawberries, and tomatoes. Different materials reflect and absorb different wavelengths of light, and PestiSCAND can look for the specific wavelengths related to the pesticide residues.

After scanning the food, PestiSCAND uses an AI machine learning model to analyze the lightwaves to determine the presence of pesticides. With its sensor and processor, the prototype achieved a detection accuracy rate of greater than 85%, meeting the project’s objectives for effectiveness and speed.

Sirish plans to continue working on the prototype with a price-point goal of just $20 per device, and hopes to get it to market by the time he starts college." [Note: That's in 4 years.]

The amount of posts I’ve seen lately on r/whatsthisbug of fly eggs deposited on food that’s been left out is WILD. Please...please. Cover food that is left on the counter or wherever during fly season. ESPECIALLY at outdoor picnics. It only takes a couple minutes for a fly to lay a huge cluster of eggs onto food.

They look kinda like clusters of tiny rice:

In just one month, approximately 462 hectares (4.6 million m²) of woodland, "notably pines and oaks, as well as around 20 hectares of centuries-old olive groves," have been destroyed by Israeli airstrikes, said Georges Mitri, Director of the Land and Natural Resources Programme at Balamand University. Since the escalation of tensions between Hezbollah and the Israeli army on Oct. 8, the latter has used white phosphorus to set fire to forests and fields in border areas. The 1980 Geneva Convention, which Israel has not signed, prohibits the use of white phosphorous on civilians and in civilian areas due to its devastating effects on humans, animals and the environment.

[...]

Amid the ongoing economic crisis, the attacks targeting olive groves ahead of harvest season have a major negative impact on the local economy in the area. "Traditionally, people gather around the olive trees, harvest their crops, press their oil together... A big part of their lives is being lost," lamented Younes. “The olive trees being burned are centuries old," he pointed out. “If we were to replant them today, how long would it be before these fields became productive?” Giving an estimate of the economic losses attributed to the daily fires in the South, Mitri put the figure at nearly 20 million dollars. In the long term, Younes is particularly concerned about the environmental impact of the phosphorus bombs. "We have no choice but to wait until the end of hostilities before assessing the situation on the ground," he said. In Younes’ view, the greater the rate of absorption of phosphorus into the soil and water, the greater the risk of dramatic long-term consequences on Lebanon’s environment.

I'll add here that southern Lebanon has never fully recovered from 2006. There are still unexploded cluster bombs in the ground, killing and maiming people. There is still chemical contamination. The economic impact on agriculture has never been fully recouped. The cancer rates are still elevated and unaddressed. The labor structure and which crops are grown changed after 2006 and have never reverted. I remember weeping watching the bombing of Gaza in 2021 as I was in the middle of writing a paper about the long term legacies of the July War in Lebanon, with these additional long-term violences of the bombing at the forefront of my mind along with the immediate deaths and tragedies. This is a horrifying compounding of an existing injury, at a time when Lebanon is in economic free fall and (as the article also explains) in the middle of fire season, and with firefighters unable to do much because the area is. being bombed.

of fucking course.....they fucking coated paper straws with pfas......its a fucking nightmare

--

Long-lasting 'forever chemicals', which can cause damaging health issues, found in 18/20 brands of paper straws

In the first analysis of its kind in Europe, and only the second in the world, Belgian researchers tested 39 brands of straws for the group of synthetic chemicals known as poly- and perfluoroalkyl substances (PFAS).

PFAS were found in the majority of the straws tested and were most common in those made from paper and bamboo, the study, published in the peer-reviewed journal Food Additives and Contaminants, found.

PFAS are used to make everyday products, from outdoor clothing to non-stick pans, resistant to water, heat and stains. They are, however, potentially harmful to people, wildlife and the environment.

They break down very slowly over time and can persist over thousands of years in the environment, a property that has led to them being known as "forever chemicals."

They have been associated with a number of health problems, including lower response to vaccines, lower birth weight, thyroid disease, increased cholesterol levels, liver damage, kidney cancer and testicular cancer.

"Straws made from plant-based materials, such as paper and bamboo, are often advertised as being more sustainable and eco-friendly than those made from plastic," says researcher Dr Thimo Groffen, an environmental scientist at the University of Antwerp, who is involved in this study.

"However, the presence of PFAS in these straws means that's not necessarily true."

A growing number of countries, including the UK and Belgium, have banned sale of single-use plastic products, including drinking straws, and plant-based versions have become popular alternatives.

A recent study found PFAS in plant-based drinking straws in the US. Dr Groffen and colleagues wanted to find out if the same was true of those on sale in Belgium.

To explore this further, the research team purchased 39 different brands of drinking straw made from five materials -- paper, bamboo, glass, stainless steel and plastic.

The straws, which were mainly obtained from shops, supermarkets and fast-food restaurants, then underwent two rounds of testing for PFAS.

The majority of the brands (27/39, 69%) contained PFAS, with 18 different PFAS detected in total.

The paper straws were most likely to contain PFAS, with the chemicals detected in 18/20 (90%) of the brands tested. PFAS were also detected in 4/5 (80%) brands of bamboo straw, 3/4 (75%) of the plastic straw brands and 2/5 (40%) brands of glass straw. They were not detected in any of the five types of steel straw tested.

The most commonly found PFAS, perfluorooctanoic acid (PFOA), has been banned globally since 2020.

Also detected were trifluoroacetic acid (TFA) and trifluoromethanesulfonic acid (TFMS), "ultra-short chain" PFAS which are highly water soluble and so might leach out of straws into drinks.

The PFAS concentrations were low and, bearing in mind that most people tend to only use straws occasionally, pose a limited risk to human health. However, PFAS can remain in the body for many years and concentrations can build up over time.

"Small amounts of PFAS, while not harmful in themselves, can add to the chemical load already present in the body," says Dr Groffen.

It isn't known whether the PFAS were added to the straws by the manufacturers for waterproofing or whether were the result of contamination. Potential sources of contamination include the soil the plant-based materials were grown in and the water used in the manufacturing process.

However, the presence of the chemicals in almost every brand of paper straw means it is likely that it was, in some cases, being used as a water-repellent coating, say the researchers.

The study's other limitations include not looking at whether the PFAS would leach out of the straws into liquids.

Dr Groffen concludes: "The presence of PFAS in paper and bamboo straws shows they are not necessarily biodegradable.

"We did not detect any PFAS in stainless steel straws, so I would advise consumers to use this type of straw -- or just avoid using straws at all."

Why You Should NEVER Drink From Paper/Plastic Cups

These cups contain a variety of harmful substances such as fluoride, lead, cadmium, microplastics, and more, which leach into the liquid you're drinking. 🤔

Started the day by reading this article from the NY times, and I'm frankly, disturbed.

Some highlights:

"For decades, farmers across America have been encouraged by the federal government to spread municipal sewage on millions of acres of farmland as fertilizer. It was rich in nutrients, and it helped keep the sludge out of landfills."

Which I knew, and I knew that there were concerns about contaminants from like, the medications people were on. But human waste is part of the nutrient cycle, and it always made sense to me that it should be throughly composted and returned to agricultural lands, and I assumed that people in general were taking the steps necessary to make it safe.

But here's what I didn't know:

"The 1972 Clean Water Act had required industrial plants to start sending their wastewater to treatment plants instead of releasing it into rivers and streams, which was a win for the environment but also produced vast new quantities of sludge that had to go somewhere."

Which, yay, no longer polluting bodies of water, but now that means we're applying industrial waste water to agricultural lands. And have been since 1972. Which leads to this situation, among many others, I'm sure:

"The sludge that allegedly contaminated the Colemans’ farm came from the City of Fort Worth water district, which treats sewage from more than 1.2 million people, city records show. Its facility also accepts effluent from industries including aerospace, defense, oil and gas, and auto manufacturing. Synagro takes the sludge and treats it (though not for PFAS, as it’s not required by law) then distributes it as fertilizer."

So here's what some states are doing:

"In Michigan, among the first states to investigate the chemicals in sludge fertilizer, officials shut down one farm where tests found particularly high concentrations in the soil and in cattle that grazed on the land. This year, the state prohibited the property from ever again being used for agriculture. Michigan hasn’t conducted widespread testing at other farms, partly out of concern for the economic effects on its agriculture industry.

In 2022, Maine banned the use of sewage sludge on agricultural fields. It was the first state to do so and is the only state to systematically test farms for the chemicals. Investigators have found contamination on at least 68 of the more than 100 farms checked so far, with some 1,000 sites still to be tested.

“Investigating PFAS is like opening Pandora’s box,” said Nancy McBrady, deputy commissioner of Maine’s Department of Agriculture."

This is fun:

"The E.P.A. is currently studying the risks posed by PFAS in sludge fertilizer (which the industry calls biosolids) to determine if new rules are necessary.

The agency continues to promote its use on cropland, though elsewhere it has started to take action. In April, it ordered utilities to slash PFAS levels in drinking water to near zero and designated two types of the chemical as hazardous substances that must be cleaned up by polluters. The agency now says there is no safe level of PFAS for humans...

It’s difficult to know how much fertilizer sludge is used nationwide, and E.P.A. data is incomplete. The fertilizer industry says more than 2 million dry tons were used on 4.6 million acres of farmland in 2018. And it estimates that farmers have obtained permits to use sewage sludge on nearly 70 million acres, or about a fifth of all U.S. agricultural land."

There's more, but I wanted to condense it at least a little bit. I am glad we're raising awareness, and I'm glad we're starting to regular the amount in our drinking water, and I hope that we'll find a way to actually deal with PFAS. I am so frustrated that people are exposed in the first place, and in nigh inescapable ways.

Also, to all those people who were like, oh, organic isn't at all healthier for consumers? Guess what the organic standards don't allow to be applied?

The Yukon government says mercury levels that “exceeded the water quality objective” were found in a creek near the site where a mine’s ore containment facility failed, causing a torrent of cyanide-contaminated rock to escape in June. A statement from the government says high levels of cyanide and dissolved metals continue to be detected in the groundwater at testing sites closest to the Eagle Gold mine slide where millions of tonnes of ore was released. The statement Friday says officials aren’t seeing unsafe levels of cyanide in the downstream environment, but on Sept. 24 and 26, “the mercury level exceeded the water quality objective at one monitoring station” south of the site. The statement says the government is gathering more information to understand the data and its impacts on the environment 480 kilometres north of Whitehorse.

Just learning about that rescue with the rabid puppies, honestly its wild. People are so far removed from the danger of rabies like of course those puppies had to be put down. If they weren't they would have to be put into isolation for a very long time which would be extremely cruel and it's honestly extremely likely they were infected. Puppies lick and bite things and it's so unfortunate. That rescue though is pretty shady I do hope the public remembers this because rabies isn't something you play around with.

"An environmental toxicologist in California is cleaning up areas contaminated with heavy metals or other pollutants using fungi and native plants in a win-win for nature.

Where once toxic soils in industrial lots sat bare or weed-ridden, there are now flowering meadows of plants and mushrooms, frequented by birds and pollinators: and it’s thanks to Danielle Stevenson.

Founder of DIY Fungi, the 37-year-old ecologist from UC Riverside recently spoke with Yale Press about her ongoing work restoring ‘brownfields,’ a term that describes a contaminated environment, abandoned by industrial, extraction, or transportation operations.

A brownfield could be an old railway yard or the grounds of an abandoned oil refinery, but the uniting factor is the presence of a toxic containment, whether that’s a petrochemical, heavy metal, or something else.

Noting that she had read studies about mushrooms growing around the Chernobyl nuclear plant, she came to understand further, through her work, that fungi are an extraordinarily resilient species of life that consume carbon, and even though petroleum products are toxic to plants, to mushrooms they are essentially a kind of carbon.

In fact, mushrooms break down several categories of toxic waste with the same enzymes they use to consume a dead tree. They can also eat plastic and other things made out of oil, like agrochemicals.

At the Los Angeles railyard, as part of a pilot project, Stevenson and colleagues planted a variety of native grass and flower species alongside dead wood that would incubate specific fungi species called arbuscular mycorrhizal fungi, which assists plants in extracting heavy metals like lead and arsenic from the soil.

Alongside traditional decomposer fungi, the mixture of life forms demonstrated tremendous results in this brownfield.

“In three months we saw a more than 50 percent reduction in all pollutants. By 12 months, they were pretty much not detectable,” Stevenson told Yale 360.

Decontaminating soil like this typically involves bringing in a bulldozer and digging it all up for transportation to a landfill. This method is not only hugely expensive, but also dangerous, as contaminated material can scatter on the winds and fall out of the backs of trucks carting it away.

By contrast, the plants that draw out the toxic metals can be harvested and incinerated down to a small pile of ash before cheap transportation to a hazardous waste facility.

The technique, which Stevenson says has some scaling issues and issues with approval from regulators, is known officially as bioremediation, and she’s even used it to safely break down bags of lubricant-soaked rags from bicycle repair shops.

“People who live in a place impacted by pollution need to have a say in how their neighborhood is being cleaned up. We need to empower them with the tools to do this,” she said."

How do you explain to someone without OCD that they can’t go in your room anymore because they are going into your safe space too often and you are convinced they are trying to kill you? Like genuinely, my brain is saying it’s so suspicious they want to be in my safe space so often and I keep having panic attacks because I’m having so many intrusive thoughts of, “I have to kill you before you kill me”
