Description:

Long Island Sound (LIS) is one of the largest estuarine systems on the Atlantic coast of the United States, providing vital transportation and rich fishing and shell-fishing grounds for commercial interests. The Sound, however, has been contaminated with various pollutants, including organochlorine pesticides such as chlordane (a persistent, bioaccumulative pesticide widely used in the United States from 1945 to 1988). Limited long-term monitoring data from the National Oceanic and Atmospheric Administration (NOAA) showed a decline in chlordane concentration in LIS surficial sediments after 1988. The objectives of this research project are to: (1) determine the rates of chlordane concentration decline in the surficial sediments from LIS; (2) elucidate the mechanisms that caused the chlordane concentration decline in LIS sediments; and (3) examine the chiral signature of chlordane residues in the LIS sediments to assess the significance of microbial degradation on chlordane removal.
