(Beyond Pesticides, March 2, 2020) Deadline today! Tell EPA to Ban Atrazine; Protect Children and Frogs from this Endocrine Disrupting Pesticide.
Atrazine, the second most-used herbicide in the U.S., is an insidious poison. Atrazine is known for producing developmental abnormalities in frogs.
It also affects the endocrine system and reproductive biology of humans. In addition to its agricultural uses on corn, sorghum, and sugar cane, atrazine is also used on home lawns, school grounds, and parks, where exposure to children is common. Nontoxic alternatives are available for all of these uses.
Petition to EPA‚Äôs Office of Pesticide Programs:
We have serious concerns with the proposed interim decisions on reregistration of three triazine pesticides: atrazine, simazine, and propazine. These triazines are highly mobile and persistent in the environment and have been linked to numerous adverse health and environmental effects which have motivated numerous public interest campaigns to ban their use in the U.S. as well as in Europe. The Draft Ecological Risk Assessments for the Registration Review of Atrazine, Simazine, and Propazine dated October 5, 2016 found high risks that were supported by EPA’s assessments.
EPA’s Proposed Interim Decisions present data demonstrating unreasonable adverse effects. These hazards are unacceptable, especially in light of the availability of nontoxic alternatives. The hazards include:
*The technical mechanism of toxicity is perturbation of the neuroendocrine system by disrupting hypothalamic regulation of the pituitary, leading primarily to a disturbance in the ovulatory surge of luteinizing hormone (LH) which results in both reproductive and developmental alterations. Of the numerous adverse effects associated with this disruption, the two that appear to be the most sensitive and occur after the shortest duration (4 days) of exposure are the disruption of the ovarian cycles and the delays in puberty onset.
*Despite these endocrine disrupting effects, EPA reduces the margin of safety and underestimates exposure to children.
*EPA states, ‚ÄúBased 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, this risk assessment concludes that aquatic 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.‚ÄĚ
*In spite of these findings, EPA will increase the level of atrazine allowed in waterways.
Please adhere to the statutory mandate of the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) and suspend the registration of these pesticides that pose unreasonable adverse health and environmental effects.
