Organochlorine Contaminants in Aquatic Resources from the Columbia River
Listed in NASA Earthdata CMR
The Columbia River Estuary is exposed to a variety of contaminants through municipal and industrial permitted discharges, urban and industrial nonpoint pollution, accidental spills of oil and hazardous materials, agricultural runoff, and accelerated population growth (Schuler 1992).
Description
This study intended to provide information needed to determine if hazardous concentrations of organic pollutants are accumulating in fish and wildlife from the Columbia River and its National Wildlife Refuges.
Sediment, aquatic invertebrates, fish, and bird egg samples were collected for this study. Preliminary study results were reported in Schuler (1992). The area of study was Columbia River - Grays Bay to Umatilla.

Target analytes were dioxins and furans; PCBs; organochlorine pesticides; mercury. Analytical techniques included Dioxins/furans (EPA Method 1613). All results are reported on a dry weight basis.
Total dioxin and furan concentrations were determined by the laboratory as the sum of the individual congeners that were detected. The method for determination of total PCBs was not described. The information for this metadata was taken from the Columbia River Basin: Sediment Database Abstracts.
