Description:

Dated cores collected from different sites in the Savannah Estuary were analyzed for 16 metals, 22 polycyclic aromatic hydrocarbons (PAH), 20 polychlorinated biphenyls (PCB) congeners, 16 pesticides and 3 butyltins. Time stratigraphy of the cores were determined by measurements of 210Pba nd 137Csa ctivities down the cores. Those chemicals which showed significant temporal changes down dated cores in the Savannah Estuary included mercury, lead, chromium, PAHs, DDT isomers and metabolites, PCBs and dieldrin. The changes were most pronounced in Core H which was from the most industrialized area of the Savannah Estuary and near the city of Savannah. There was a large increase in PAH concentrations in Core H from the 1949 layers to 1958 layers followed by a gradual decrease to the surface (1993). Fluoranthene, pyrene and perylene were the major PAHs in all cores. Chromium concentrations in Core H roseduring the 1950s followed by a decrease in the late 1960s. In 1968 there was a sharp peak in mercury concentrations in Core H. Lead concentrations increased in the 1940s and 1950s followed by a decrease in the late 1960s. The increase in metal and PAH concentrations are likely due to the increased development of the port of Savannah in the 1950s and 1960s. The subsequent decrease in the concentration is presumably due to the effect of pollution controls applied to those industries, since industrial growth has continued up to the present.
