Biological/Chemical Survey of Texoma and Capline Sector Salt Dome Brine Disposal Sites Off Louisiana, 1978-1979. Volume VII. Determine Trace Metal Composition and Concentration in Major Components of the Ecosystem

摘要

Investigations were made at the West Hackberry and Weeks Island proposed brine diffuser sites during four consecutive seasons (1978-79). Samples of suspended particulate matter, epibenthic organisms and macrocrustaceans were collected during all four seasons. The spacial and temporal distributions of 13 trace metals were determined in each sample matrix. Higher metal concentrations in sediments from the West Hackberry site are in agreement with the higher amounts of silt, clay and organic carbon reported in these sediments. There are indications of seasonal variations of Ba, Cd and Hg in Penaeus setiferus (white shrimp) muscle tissues.
