Abstract
The objective of this study was to conduct a series of 28 d partial life cycle atrazine sub chronic toxicity tests with sago pondweed, Potamogeton pectinatus, at salinities of 1, 6 and 12 ppt. These data will be used by Maryland Department of the Environment for development of a chronic estuarine criterion for atrazine in Maryland waters of Chesapeake Bay. The three endpoints used for this submerged aquatic macrophyte were final wet weight, final dry weight and final number of rhizome tips at the termination of the 28 day test.
