Incidence and Severity of Sediment Contamination in Surface Waters of the UnitedStates. Volume 1. National Sediment Quality Survey

摘要

This report describes the accumulation of chemical contaminants in river, lake,ocean, and estuary bottoms and includes a screening assessment of the potential for associated adverse effects to human and environmental health. It represents the first comprehensive EPA analysis of sediment chemistry and related biological data to assess what is known about the national incidence and severity of sediment contamination. EPA studied available data from sixty-five percent of the 2,111 watersheds in the continental United States and identified ninety-six watersheds that contain 'areas of probable concern.'
