Investigation of chlorinated pesticides and polychlorinated biphenyls (PCBs) in
samples of water and sediment were made near sewage and power plant outfalls, freshwater
tributaries, and agricultural runoff canals located along the Indian River between Vera Beach
and St. Lucie Inlet. Chlorinated pesticide residues and PCB were not detected in surface water
samples. Concentrations of several compounds such as DDT and PCB (Aroclor 1254) were low in
sediment samples ( < 0.1 ppm), although they were detected at least once in most samples. The
persistence of malathion and parathion decreased with increasing pH and salinity. When temp
was above 26°C and salinity above 20 ppt, hydrolysis was the predominant pathway of degradation
of malathion and biological interaction was the most significant pathway of degradation for
parathion. Industrial chemicals such as trichloroethylene and other volatile organic compounds
are currently being monitored in the Main Relief Canal and Indian River at Vera Beach.
Background levels of trichloroethylene were low in both water and sediment samples (< 0.1 ppb
and = 0.5 ppb, respectively). Florida Atlantic University.
