Magnitude and Extent of Contaminated Sediment and Toxicity in San Francisco Bay

Magnitude and Extent of Contaminated Sediment and Toxicity in San Francisco Bay

Abstract

The purpose of this study is to describe the environmental conditions in the San Francisco Bay in terms of sediment contamination, toxicity, and associated adverse biological effects. The expected outcomes are; 1) determination of the incidence and degree of surficial sediment toxicity, 2) determination of the spatial patterns or gradients in chemical contamination and toxicity, if any and, 3) determination of the association among measures of sediment contamination, toxicity and the benthic macroinvertebrate community structure.

Objectives

The main objective of NS&T Bioeffects research is to assess the degree and spatial extent of habitat and biological resources that are impacted by chemical contamination. The objectives of the San Francisco Bioeffects Assessment Program are to 1) identify and assesses biological effects associated with contaminant exposure, 2) determine the spatial extent and severity of chemical contamination and associated adverse biological effects, 3) provide data to assess regional environmental quality improvement. Bioeffects studies support NOAA ecosystem-based management through an integrated program of environmental assessment, and research to describe the current status of pollution and to detect changes in the environmental quality of our nation's estuarine and coastal waters. These interrelated activities are designed to provide coastal managers with scientific information and tools needed to balance society’s environmental, social, and economic goals.

Time Frame

2007.
