Description:
Polychlorinated biphenyls (PCB's) have been shown to be widespread in the environment. Their significance in the aquatic environment as a poison is now being revealed. They are being detected in fish and other aquatic life at levels much higher than concentrations found in the water. The acute toxicity of some of the many types of PCB's produced commercially has been demonstrated for a few species of fish, and fish food organisms, such as shrimp, scuds, and aquatic insects; however, little information is currently available on the chronic effects of PCB on the full life cycles of aquatic animals. In order to assess the danger of these compounds to fish and fish food organisms the laboratory designed and conducted bioassays using Daphnia magna, the fathead minnow Pimephales promelas, the flagfish Jordanella floridae, the scud Gammarus pseudolimnaeus, and the midge Tanytarsus dissimilis, using commercially available PCB mixtures (Aroclor 1221, 1232, 1242, 1248, 1254, 1260, 1262, and 1268).
