Residues of polychlorinated biphenyls and DDT in water and sediment of the Indian River Lagoon, Florida--1977-78. 1980

T C Wang, and R S Johnson, and J L Bricker

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.

D010573	Pesticide Residues	Pesticides or their breakdown products remaining in the environment following their normal use or accidental contamination.	Pesticide Residue,Residue, Pesticide,Residues, Pesticide
D011078	Polychlorinated Biphenyls	Industrial products consisting of a mixture of chlorinated biphenyl congeners and isomers. These compounds are highly lipophilic and tend to accumulate in fat stores of animals. Many of these compounds are considered toxic and potential environmental pollutants.

D003634	DDT	A polychlorinated pesticide that is resistant to destruction by light and oxidation. Its unusual stability has resulted in difficulties in residue removal from water, soil, and foodstuffs. This substance may reasonably be anticipated to be a carcinogen: Fourth Annual Report on Carcinogens (NTP-85-002, 1985).
