Toxaphene Interactions in Estuarine Ecosystems.

摘要

During 1973-1974, the toxaphene concentration in effluent from the Brunswick manufacturing plant continued to decrease from around 30 ppb to near 6 ppb. Concurrent with this was an increase in the species diversity of organisms in waters receiving the effluent. During 1973-1974 the diversity index, H Bar, was 1.9977 in the Duplin Estuary (considered to be undisturbed and free from any toxaphene contamination) contrasted with a higher index of 2.2577 in Terry Creek (which receives effluent containing toxaphene). Experiments to follow the movement of toxaphene from the substrate into the salt marsh cordgrass, Spartina alterniflora, using 36 Chlorine labeled toxaphene were initiated.
