Its a pretty interesting report, and one that definitely seems to point to the need for greater restrictions.
That being said, its worth pointing out that the Center for Biological Diversity's summary of the report is a little off-center.
"[According to the EPA] the amount of the herbicide atrazine that’s released into the environment in the United States is likely harming most species of plants and animals, including mammals, birds, amphibians and reptiles"
My read of the actual report was that it states that aquatic plant communities are being harmed in areas of heaviest use, and that there is "potential chronic risk to fish, amphibians, and aquatic invertebrates in these same locations". There are "risk concerns" for birds, mammals, reptiles and plants associated with certain uses of atrazine nationwide. Apparently some uses involve larger amounts of atrazine than others.
Atrazine is well known as a hormone disrupter, that has been linked to birth defects and cancer...
EPA: Generally agrees with characterization as an endocrine disrupter. It has classified atrazine as a non-carcinogen in the past and is re-evaluating as part of the scheduled re-registration process. Birth defect association appears to be controversial
with EPA “levels of concern” surpassed nearly 200-fold...
My read of the report was that this was true for a few weeks at a few locations, rather than being typical nationwide as implied by CBD.
The EPA has determined that the amount of atrazine that’s in streams and rivers right now is enough to kill frogs and other imperiled wildlife.
Again, during a few weeks and at a few locations
Dr. Tyrone Hayes, at the University of California, has shown that atrazine chemically castrates and feminizes male frogs at concentrations lower than the level allowed in drinking water by the EPA.
Several other labs, such as this one, have not been able to reproduce Hayes' work. However atrazine does seem to suppress the immune system of frogs in a way that seriously affects their viability. That seems a lot less controversial, but perhaps does not have the "click appeal" of sex-changing frogs.
Currently 70 million pounds of atrazine are used in the United States each year, contaminating ground, surface and drinking water.
The EPA data clearly seems to show there is a problem here.
All in all, not great coverage by CBD, but I'd have to agree with them that atrazine needs additional restrictions, and maybe its time to ban it outright.
