New Report Details How trumpanzee's EPA Is Promoting 'Worst of the Worst Pesticides' The EPA approved **15 new products containing neurotoxic carbamates or organophosphates (OPs), including chlorpyrifos. **17 new products containing the endocrine disruptor atrazine. **Six new products containing paraquat, which is so lethal that one spoonful can kill a full-grown adult. **Four new products containing the extremely dangerous airborne fumigants methyl bromide or chloropicrin. **91 new restricted-use pesticides, so dangerous they can only be applied by a professional. **69 new products containing an ingredient the EPA recognizes as a "known" or "likely" carcinogen. Roughly a third of the products approved over the two-year period have more than one active ingredient, with some containing as many as six. That's cause for concern. From the report: When the EPA analyzes the harms associated with pesticides, it only takes into account exposure to a single active ingredient at a time. This practice fails to fully capture the risk and potential harms that can be caused by 1 out of every 3 products it's approving. This is in addition to the EPA's refusal to consider the impacts of interactions between active ingredients and other ingredients in formulated products that can result in increased toxicity. This refusal to analyze harm from ingredient mixtures, the same mixtures that are sold on store shelves, calls into question the effectiveness of a risk- assessment process that ignores these highly relevant exposures.

A new study suggests an underestimation of microplastics in the ocean. By using finer sampling nets (researchers) have built a picture of the extent to which microplastics in coastal waters have been underestimated. The findings show a 2.5- and 10-fold greater microplastic concentration. "https://phys.org/news/2020-05-underestimating-microplastics-marine- environment.html" A new study from the University of Central Florida has confirmed and quantified, for the first time, the presence of microplastics in terrestrial and aquatic birds of prey in Florida, including hawks, ospreys and owls. Past studies have documented increasing amounts of microplastics in the guts of fish, marine birds, and filter-feeding invertebrates, such as oysters. There have also been recent reports of whales dying from eating dozens of pounds of plastic, including plastic bags. However, birds of prey have not been thoroughly examined before, partly due to their protected status. Carlin and Walters were able to overcome this by working with the Audubon Center for Birds of Prey in Maitland, Florida, a rehabilitation center that helps injured raptors. With the center's permits, UCF researchers were able to examine the stomach contents of 63 birds that were dead when they arrived at the center or died 24 hours after they arrived. The birds were collected from throughout Central Florida. Using dissecting microscopes and spectroscopy, the researchers found microplastics in the digestive systems of all birds examined, with nearly 1,200 pieces of plastic pulled from the 63 birds.
