Robustness of supercritical fluid extraction (SFE) in environmental studies: Analysis of chlorinated pollutants in tissues from the osprey (Pandion haliaetus) and several fish species
To investigate the effects of imidacloprid on natural stream communities under controlled conditions, experimental streams were dosed with imidacloprid at concentrations ranging from 0.061 to 220 micrograms per liter (µg/L) for a period of 10 days. Natural stream macroinvertebrate communities were obtained from the Cache La Poudre River (Larimer County, CO) by colonizing trays full of large gravel for 75 days. The trays were added to laboratory experimental streams (mesocosms) at the USGS Fort Collins Science Center in Fort Collins, CO. At the end of 10 days, invertebrate abundance metrics were analyzed in relation to measured imidacloprid concentrations in water from the experimental streams. Declines in total...
Welcome to the USGS Pacific Islands Water Science Center’s (PIWSC) catalog and repository space. The purpose of this space is to make available datasets and data products, and to establish linkages to associated publications. The mission of the USGS Pacific Islands Water Science Center is to provide reliable and impartial scientific information needed to understand the quantity and quality of water resources in Hawaii and U.S. affiliated Pacific Islands.
