COLUMBIA RIVER BASIN CONTAMINANT AQUATIC BIOTA AND SEDIMENT DATA
Description:
Numerous studies have been done to determine the levels of chemical contaminants in fish and sediment in the Columbia River Basin. These studies were done because of concern that releases of toxic Chemicals into the Columbia River Basin may be impacting health and the environment. To make it easier for regulatory agencies, research institutes, and the public to access these data, the U.S. EPA funded a contractor to compile these data into 2 databases. A compilation of chemical analytical data from numerous studies on sediment and aquatic biota in the Columbia River Basin is contained in two databases, an aquatic biota database and a sediment database. Sources of data include studies done by government agencies, universities, and private firms. The abstract files accompanying the databases more fully describe the data sources and associated reports. Aquatic Biota Database. Data: Assimilated from 21 reports Sample Collection Dates: 1987 through 1993 Aquatic Biota and Chemical Groups Analyzed: Data is limited to aquatic vertebrates and crustaceans. Chemical groups include Butylins, Dioxin/furans, Metals, PCBs, Pesticides, Radionuclides, and Semi-volatiles. Sediment Database. Data: Assimilated from 31 reports Sample Collection Dates: 1984 through 1994 Chemical Groups Analyzed: Data from multiple sediment depths were compiled for Butylins, Dioxin/furans, Guaiacols/Catechols/Phenolics, Resins/Fatty Acids, Metals, PCBs, Pesticides, Radionuclides, Semi-volatiles, Volatiles.
