| Abstract |
This paper provides a synthesis of research conducted on possible causes of the decline in abundance of submerged aquatic vegetation (SAV) in upper Chesapeake Bay beginning in the late 1960's. Three factors potentially were emphasized in this study: Runoff of agricultural herbicides; erosional inputs of fine-grain sediments; nutrient enrichment and associated algal growth. Widespread use of herbicides in the estuarine watershed occurred contemporaneous with the SAV loss; however, extensive sampling of estuarine water and sediments during 1980-81 revealed that typical bay concentrations of herbicides (primarily atrazine) rarely exceeded 2ppb. |
