Mammals metabolize some pesticides to limit their biomagnification
The concentrations of many historically used, and now widely banned, pesticides and other toxic chemicals -- called legacy contaminants -- can become magnified in an animal that eats contaminated food; however, a new Environmental Toxicology & Chemistry study has found that Arctic mammals metabolize some currently used pesticides, preventing such 'biomagnification.'

Common pesticides kill amphibian parasites, study finds
A recent study by Jessica Hua, assistant professor of biological sciences at Binghamton University, and colleagues, explored the effects of six commonly used pesticides on two different populations of a widespread parasite of amphibians. They found that a broad range of insecticides commonly used in the US kill amphibian parasites, which could potentially decrease the number of parasites that amphibians must defend against. For the pyrethroid and neonicotinoid pesticides tested in this study, this pattern has not been documented before. (2016-04-04)

Homes pollute: Linked to 50 percent more water pollution than previously believed
Scientists are reporting some unsettling news about homes in the residential areas of California. The typical home there -- and probably elsewhere in the country -- is an alarming and probably underestimated source of water pollution, according to a new study scheduled for presentation in August at the 238th National Meeting of the American Chemical Society. (2009-08-19)

Pesticide combination affects bees' ability to learn
Two new studies have highlighted a negative impact on bees' ability to learn following exposure to a combination of pesticides commonly used in agriculture.
