Abstract

The goal of this study was to examine the use of a constructed wetland to mitigate the ecological impacts of simulated diazinon runoff from agricultural fields into receiving waters via 48 h aqueous and sediment bioassays using Hyalella azteca Aqueous animal 48 h survival varied temporally and spatially in conjunction with measured diazinon concentrations Sediment H azteca survival varied temporally and spatially in conjunction with measured diazinon concentrations but less than aqueous exposures confirming that sediment bound diazinon was less bioavailable than aqueous diazinonAppreciation is extended to L Arbuckle and R W Steinriede for sample collection and bioassay assistance as well as Erin Bennett Kristie Willett and Lloyd Southwick for reviewing earlier versions of the manuscript Mention of equipment computer programs or a pesticide does not constitute an endorsement for use by the US Department of Agriculture nor does it imply pesticide registration under FIFRA as amended All programs and services of the USDA are offered on a nondiscriminatory basis without regard to race color national origin religion sex marital status or handicap
