ABSTRACT

A variety of pesticides are applied in large quantities to agricultural and urban areas in the Central Valley of California and are transported into the San Francisco Bay-Estuary dissolved in water and associated with suspended sediments. These pesticides can have deleterious effects on aquatic organisms. Three studies that relate pesticide concentrations to potential effects on aquatic organisms are currently underway by the U.S. Geological Survey's San Francisco Bay-Estuary Toxic Substances Hydrology Project. These studies are (1) measuring the impacts of herbicides on phytoplankton primary production, (2) determining the exposure of Delta smelt to dissolved pesticides, and (3) assessing the effects of pesticides on the Asian clam, Potamocorbula amurensis.
