The Environmental Protection Agency released a very troubling preliminary risk assessment that the routine use of the chemical atrazine is likely harming animals and our ecosystems.
Atrazine is manufactured and distributed by Syngenta, a foreign global chemical company, that markets the product in the US to limit plants that may compete with commodity crops or would be considered weeds on golf courses.
The EPA memo that was released was hand-signed by six scientists in the US government’s Environmental Risk Branch of the Environmental Fate and Effects Division. The 500+ page study was co-authored by Dr. Frank T. Farrugia, Colleen M. Rossmeisl, Dr. James A. Hetrick, and Melanie Biscoe, and was subject to peer review by twelve other scientists.
Its top-line findings are “based on the results from hundreds of toxicity studies on the effects of atrazine on plants and animals, over 20 years of surface water monitoring data, and higher tier aquatic exposure models.”
Specifically, after extensive review, the EPA’s Risk Assessment Branch section found that (emphasis added):
[A]quatic plant communities are impacted in many areas where atrazine use is heaviest, and there is potential chronic risk to fish, amphibians, and aquatic invertebrates in these same locations.
In the terrestrial environment, there are risk concerns for mammals, birds, reptiles, plants and plant communities across the country for many of the atrazine uses.
EPA levels of concern for chronic risk are exceeded by as much as 22, 198, and 62 times for birds, mammals, and fish, respectively.
For aquatic phase amphibians, a weight of evidence analysis concluded there is potential for chronic risks to amphibians…
The breadth of terrestrial plant species and families potentially impacted by use at current labeled rates, as well as reduced rates of .5 and .25 lbs a.i./A, suggests that terrestrial plant biodiversity and communities are likely to be impacted from off-field exposures via runoff and drift.
Average atrazine concentrations in water at or above 5 ug/L for several weeks are predicted to lead to reproductive effects in fish [and a lower amount over 60 days] has a high probability of impacting aquatic plant community primary productivity, structure and function.
In layperson’s terms that means that independent government scientists have a high level of concern about the risks to mammals, amphibians, fish, birds, and plants when Syngenta’s “weed-killer” is used in quantities recommended by the company.
Atrazine has been barred in Europe since 2004.
Despite the seriousness of the concerns about the adverse effects of atrazine — or perhaps because of them — the memo, which was signed on April 12 and published last week, was quietly removed from the EPA’s website. The Center for Biological Diversity preserved a copy and made it available here.
According to Open Secrets, Syngenta spends well over a million dollars a year on reported lobbying of Congress and federal agencies to limit the regulation of the chemicals it markets to American businesses and consumers, in addition to an untold sum on public relations in the US.
As noted by data on file with the Center for Responsive Politics, executives of its US operation which is called Syngenta Crop Protection — including SCP president Vernon Hawkins — have contributed to CropLife America, which in turn gives money predominately to Republicans and also to a Republican PAC called AG America. (Some employees have donated to President Obama’s past campaigns and to other Democrats as well as to Republicans.)
Syngenta, which is based in Basel, Switzerland, reported revenue of $13.4 billion dollars last year, 3.4 billion of which was from sales in North America from atrazine and other products. Last year, it reported spending more than $2 billion globally on marketing and distribution.
The company is often described is the largest pesticide manufacturer in the world, and just last year it deflected an attempted merger by Monsanto, an even larger global chemical company (one with an even wider array of controversial products and practices).
As part of a major investigation in 2012, the Center for Media and Democracy’s PRWatch documented Syngenta’s PR plan to hide behind chemical industry front groups, like the self-named “American Council on Science and Health” (ACSH) to try to sway public opinion.
As CMD/PRWatch noted: “Documents obtained by CMD show show that Syngenta has been a long-term financial supporter of ACSH and that in the midst of reports about spikes in atrazine levels reported by the New York Times, the Natural Resources Defense Council, and the Huffington Post Investigative Fund, ACSH sought an additional $100,000 to produce more materials about atrazine in addition to seeking increased funding in general by Syngenta.”
Specifically, Gilbert Ross (a physician who was convicted of fraud) who is a long-time leader of ACSH wrote to its “Dear Syngenta friends” that it was eager to do that $100K project, which was “separate and distinct from general operating support Syngenta has been so generously providing over the years” to fund ACSH’s operations, funding ACSH called “the lifeblood” of its work. That document, which can be downloaded below, was filed with a court in litigation over Syngenta’s Atrazine.
Last year, CMD published additional details about ACSH and the corporations that have funded it — such as Altria, the American Petroleum Institute, Bayer CropScience, the Bradley Foundation, Bristol-Myers Squibb, Chevron, CropLife America, Donors Capital Fund, DonorsTrust, ExxonMobil, PhRMA, the Randolph Foundation, and Searle Freedom Trust and more — with its many controversial claims and agenda items, here.
CMD’s initial investigation of Syngenta was based on documents in court filings that CMD reviewed.
Those documents also revealed how Syngenta’s PR team targeted scientists, like Dr. Tyrone Hayes, and reporters, like Huffington Post’s Danielle Ivory, and how they launched a multi-pronged campaign to spin public perception in the face of growing concerns about potential health risks of atrazine.
Hayes’ suspicions — that he was being investigated and undermined by Syngenta in response to his studies tying frog mutations to atrazine exposure — were confirmed by the documents CMD published as part of its investigation.
The effects on him and his career as an independent scientist were the topic of a major New Yorker article in 2014.
Since CMD exposed Syngenta’s PR scheme, the US Chamber of Commerce has been paying for Google ads for the past four years attacking CMD, among other attempted retaliatory efforts by Syngenta or its allies.
Regarding the EPA’s study of atrazine, Dr. Warren Porter, a renowned toxicologist at the University of Wisconsin-Madison, told CMD:
“Atrazine alters sexual hormone levels, and the effects of that, especially at the embryonic stage, can be life-threatening or have life-long impacts. If it affects the immune system, and it can, then it can be life-threatening, or cause long-term chronic inflammation and all kinds of long-term chronic disease. The nervous, endocrine and immune systems are all interconnected, and if you get hit on any of them, you’re likely to get hit on them all.”
Atrazine is the second-most widely used herbicide in the US (behind Monsanto’s glyphosate product, Roundup), with more 70 million pounds entering our environment each year.
