  • Title: Residues of polychlorinated biphenyls and DDT in water and sediment of the Indian River Lagoon, Florida--1977-78.

    Journal: Pestic Monit J; 1980; 13(4):141-4. PubMed ID: 6770334.
    Abstract:
    Water and sediment samples collected during 1977-78 from the Indian River lagoon between Vero Beach, Indian River County, and Fort Pierce, Saint Lucie County, Florida were analyzed for PCBs and DDT. Sample locations were chosen on the basis of proximity to major tributaries, sewage outfalls, or municipal area. Concentrations in water samples were below 0.01 ppb sigma DDT and 0.5 ppb PCBs. Small amounts of PCBs and DDT were found in most sediment samples, ranging from less than 1.0 ppb to 0.63 ppm Aroclor 1254 and from less than 0.1 ppb to 0.081 ppm sigma DDT. Samples from the Taylor Creek tributary and from the Fort Pierce power plant and municipal docking area contained higher PCB concentrations then did samples from other locations. DDT and PCB levels in most samples indicate little contamination by these compounds of the Indian River Waterway between Vero Beach and Fort Pierce.
