This excel workbook contains data from a study of trophic transfer of radiolabeled (C-14) permethrin from pyrethroid-resistant Hyalella azteca to a known predator, the Inland silverside Menidia beryllina. Fish were fed 15 dosed (~ 1 ng/animal) or control H. azteca for 14 days at three temperatures, 18, 23 and 28°C, and three salinities (6, 13 and 20 PSU) to simulate changes anticipated under global climate change (GCC). Following feeding, fish were analyzed for total permethrin concentrations, as well as percent parent compound as a a measure of biotransformation, were measured in both H. azteca and M. beryllina.
