The objectives are (a) to utilize and compare two passive sampler technologies, polyethylene devices (PEDs) and solid phase micro-extraction fibers (SPME), for monitoring the presence of DDTs and dieldrin emanating from contaminated soils and sediments into the waters of the Lauritzen Channel-Richmond Harbor-San Francisco Bay before, during, and after environmental remediation of the United Heckathorn site, and (b) to compare DDTs and dieldrin uptake by the passive samplers to bioaccumulation seen (by us) in field deployments using a bivalve and in laboratory tests using a bivalve and an amphipod and to fish collected in the area (as reported by others).
