Crab embryos from two Northern California salt marshes accumulate mixtures of currently used as well as discontinued pesticides, according to a study published by U.S. Geological Survey (USGS) and University of California scientists in the journal Environmental Toxicology and Chemistry. The scientists detected pyrethroid and organophosphate insecticides as well as 20 other pesticides, including DDT, in crab embryos using newly developed techniques at the USGS Toxic Substances Hydrology Program's Pesticide Research Laboratory....more from the source.
