In-Situ Impact Of Natural Sunlight And Tidal Action On The Composition And Toxicity Of Sediment-Associated Organic Pollutants, Robert Hale

Reports

Organic pollutants pose a haz.ard to living resources of the Chesapeake Bay and elsewhere. P AHs and other compounds present in creosote are major contaminants of concern. Polychlorinated terphenyls (PCTs), PCB-like compounds, have also been detected in high concentrations in sediments from several areas. Fates of these toxic compounds in-situ are poorly understood. In this study the impacts of physical processes operating in a tidal creek on the fate of creosote constituents (i.e. P AHs and heterocyclics) and PCTs were examined. Two representative sediments ( a coarse/low organic carbon (LOC) and a fine, high organic carbon (HOC)) were fortified with …
