||The study was designed to determine the influence of a range of salinities (5, 15 and 25 ppt) on the acute toxicity of atrazine to the copepod, Eurytemora affinis and the sheepshead minnow larvae, Cyprinodon variegatus. An additional objective of the study was to provide acute atrazine toxicity data for E. affinis to fill a data requirement for development of an estuarine water quality criterion. The conclusion from the study is that salinity influences the toxicity of atrazine to two Chesapeake Bay species but the influence is exerted in opposite ways (increased or decreased toxicity) depending on the test species.
