Ban Atrazine Poster 5501

The new EPA report, Refined Ecological Risk Assessment for Atrazine, details atrazine’s harmful effects to plant and animal species in the United States. Here is an abstract of the more than 500 pages of report here: This refined assessment presents the ecological risks posed by the use of the herbicide atrazine. 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, 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. 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 based on multiple effects endpoint concentrations compared to measured and predicted surface water concentrations. The breadth of terrestrial plant species and families potentially impacted by atrazine use at current labeled rates, as well as reduced rates of 0.5 and 0.25 lbs. a.i./A, suggest that terrestrial plant biodiversity and communities are likely to be impacted from off-field exposures via runoff and spray drift. Average atrazine concentrations in water at or above 5 μg/L for several weeks are predicted to lead to reproductive effects in fish, while a 60-day average of 3.4 μg/L has a high probability of impacting aquatic plant community primary productivity, structure and function.

"I am a former Herpetology Keeper's Assistant, and an avid nature and wildlife photography buff. I love frogs because…well, heck, how can one NOT love frogs? They have cute expressive faces, they sing into the night, and they eat lots of insects, thus helping to control the population of pests. They are also (and most unfortunately) a visual representation of the damage we are doing to the natural environment, and to the planet as a whole. They are our modern day canary in a coal mine. We would do well to heed their warning…"
