On July 24, 2024, the scientific journal Environmental Well being Views revealed a groundbreaking examine on PFAS chemical compounds in pesticides — and belief us, you’re going to need to find out about this one.
The New Groundbreaking Examine
The authors of this examine fastidiously examined public data from the U.S. and Canada to trace the usage of pesticides containing these harmful chemical compounds. Sadly, the examine discovered that these PFAS-contaminated pesticides are used all through the nation on staple crops like corn, strawberries, kale, and extra (this dangerous information comes as a second blow to strawberries and kale, which made it on to the EWG’s Soiled Dozen record for 2024 — extra on that right here).
The peer-reviewed paper, titled “Endlessly Pesticides: A Rising Supply of PFAS Contamination within the Atmosphere,” was a collaborative effort with a number of organizations, together with the Environmental Working Group (EWG), the Heart for Organic Range (CBD), and Public Staff for Environmental Duty (PEER).
The authors confirmed that these chemical compounds are hurting the setting and might have some critical unfavorable results in your well being. The examine ought to function an pressing wake-up name for the Environmental Safety Company (EPA) to tighten up pesticide manufacturing laws to guard folks and the planet.

What Are PFAS Chemical compounds, and Why Do They Matter?
PFAS stands for per- and polyfluoroalkyl substances.
This group of artificial substances is over 15,000 robust, and scientists prefer to seek advice from them as “without end chemical compounds.” That’s as a result of they don’t break down in soil and water, and might even acquire in human blood and organs, the place they will do lasting injury.
You’ll have heard of PFAS within the context of cookware — these chemical compounds are generally present in plastic-coated nonstick pots and pans (and if you wish to keep away from ingesting PFAS chemical compounds, our record of the 7 finest non-toxic cookware choices and this chef-approved non-toxic bakeware information are nice locations to start out!). The presence of PFAS in pesticides poses a brand new concern, nonetheless, because it highlights that these chemical compounds may already be current in our dinner earlier than it ever hits the pan.
This new examine reveals that pesticide producers are more and more utilizing PFAS chemical compounds to make their merchandise extra steady and efficient, however not with no value.
Nathan Donley, Environmental Well being Science Director on the CBD, explains, “Lacing pesticides with without end chemical compounds is probably going burdening the subsequent era with extra power ailments and not possible cleanup obligations.”
What’s extra, the latest analysis1 revealed in Environmental Well being Views highlights that without end chemical compounds make up a regarding 14 % of the lively components in American pesticides.
The Analysis on PFAS in Pesticides
The authors behind “Endlessly Pesticides: A Rising Supply of PFAS Contamination within the Atmosphere” are subject material specialists Nathan Donley, Caroline Cox, Kyla Bennett, Alexis M. Temkin, David Q. Andrews, and Olga V. Naidenko.

These researchers made some alarming discoveries that add a brand new sense of urgency to the struggle towards PFAS. Right here’s what we now know:
PFOA and PFOS Present in Pesticides
PFOA, or perfluorooctanoic acid, is a kind of PFAS compound that’s thought of one of many worst for human well being and the setting. The Worldwide Company for Analysis on Most cancers has gone so far as to categorise PFOA as “presumably carcinogenic to people2.”
PFOS (perfluorooctane sulfonate) is one other without end chemical that’s thought of one of the crucial regarding contaminants. Epidemiological research have proven a powerful affiliation between each PFOA and PFOS and testicular and kidney most cancers, though conclusive outcomes would require longer-term follow-up research.3.
Sadly, each PFOA and PFOS have been present in some pesticide merchandise, which Donley states are “a number of the most generally dispersed pollution on the earth.”
What Are PFAS Chemical compounds Doing in Pesticides, Anyway?
Researchers consider that PFAS chemical compounds are leaching from pesticide containers handled with fluorine. Pesticide producers fluorinate plastic containers to make them safer to make use of, however the fluorine additionally produces PFOA and PFOS as chemical byproducts. The pesticide merchandise then develop into contaminated within the containers earlier than they finally make their manner into home goods like staple produce, flea therapy for pets, and insect-killing sprays.
Water Air pollution From PFAS in Pesticides
As soon as PFAS-contaminated merchandise have been used on farms, the pesticide runoff can injury downstream water sources and contaminate ingesting provides4.
Researchers confirmed that these poisonous chemical compounds are current in our bodies of water throughout the nation — of the 13 of the 66 PFAS lively components authorized to be used in pesticides within the US, 12 have been present in American streams and rivers5. As a result of these chemical compounds are so troublesome to interrupt down, they’re a long-term menace to our water provide. (You may learn up on the devastating results of PFAs in our waterways right here.)
Why Has the EPA Uncared for PFAS in Pesticides?
PEER Science Coverage Director Kyla Bennett says, “The blame for this contamination disaster lies squarely on the EPA’s shoulders.”
Nonetheless, whereas the EPA is actually accountable, researchers inform us that the company isn’t outfitted to take care of the dangers posed by PFAS in pesticides. The latest examine concluded that the EPA continues to underestimate the affect and dangers of PFAS. Till pesticide regulators take these dangers critically, they’re prone to proceed making the identical errors.
How Does The Presence of PFAS in Pesticides Have an effect on Us?
At this level, it’s in all probability fairly clear that discovering PFAS in pesticides has been a regarding discovery for the scientific neighborhood. However how will this discovery instantly have an effect on our lives?
The Affect PFAS in Pesticides Has on Our Well being
What does the usage of PFAS in pesticides imply for our well being?
Analysis hyperlinks PFAS publicity to a number of types of most cancers6, which is simply one of many many issues with the usage of contaiminated pesticides on crops. As well as, research have established a connection between without end chemical compounds and feminine reproductive points7. That’s not all, although — PFAS in pesticides may additionally affect the onset of puberty8 and even scale back an individual’s capability to struggle off infections9. One examine even discovered a transparent hyperlink between PFAS publicity and a gradual metabolism.
For sure, it’s value doing the whole lot we will to reduce PFAS publicity.
The Affect PFAS in Pesticides Has on The Planet
PFAS chemical compounds leak into soil, pollute water, and even unfold by way of the air. Air air pollution from these chemical compounds is a serious supply of concern — PFAS contamination has been present in each indoor and out of doors air10. Endlessly chemical compounds will be carried by the wind for miles after they’re sprayed on crops, reducing the standard of the air we breathe as they journey.
As well as, as these chemical compounds accumulate in soil, water, and the our bodies of residing issues, they will dramatically scale back the planet’s biodiversity. Endlessly chemical compounds have even been discovered to lift the degrees of steroids within the brains of some animals, together with polar bears11, which might injury their reproductive well being.
Kyla Bennett mentioned it finest: “I can consider no higher method to poison folks and the setting than to spray PFAS-laden pesticides on our crops and in our properties.”
Stopping the Unfold of PFAS By means of Pesticides
The authors behind the latest examine in Environmental Well being Views supplied sensible steps that U.S. regulators can take to tighten their grip on the usage of PFAS in pesticides. The researchers’ suggestions included altering the requirements for pesticide ingredient labeling, requiring immunotoxicity exams for any PFAS components, and increasing environmental monitoring efforts.
What You Can Do to Keep away from PFAS in Pesticides
At this level, there isn’t a dependable method to keep away from PFAS chemical compounds altogether — these substances are within the air we breathe, the water used on our crops, and the soil these crops develop in. Nonetheless, consuming natural produce is one useful step you may take to cut back your publicity to PFAS by way of meals.
“I can consider no higher method to poison folks and the setting than to spray PFAS-laden pesticides on our crops and in our properties.”

Filtering your water is one other key step in the precise route. Since without end chemical compounds can seep into water and trigger long-lasting contamination, a high-quality filtration system is a worthwhile funding to your well being. Search for filters containing activated carbon or reverse osmosis membranes for one of the best PFAS filtration12 — your commonplace Brita may not reduce it on this context13.
The Backside Line on PFAS in Pesticides
In conclusion, PFAS threaten our well being and our planet, and we now know that they’re used on crops throughout the nation. The latest analysis on the affect of those chemical compounds confirms that it’s time for regulators to take the dangers critically and take steps to cease PFAS from inflicting extra injury.
