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.
1977年至1978年期间，从佛罗里达州印第安河县韦罗海滩和圣卢西县皮尔斯堡之间的印度河泻湖采集了水和沉积物样本，分析其中的多氯联苯（PCBs）和滴滴涕（DDT）。样本采集地点是根据靠近主要支流、污水排放口或市政区域来选择的。水样中滴滴涕的总浓度低于0.01 ppb，多氯联苯低于0.5 ppb。在大多数沉积物样本中发现了少量的多氯联苯和滴滴涕，浓度范围从低于1.0 ppb到0.63 ppm的氯丹1254，以及从低于0.1 ppb到0.081 ppm的滴滴涕总浓度。泰勒溪支流、皮尔斯堡发电厂和市政船坞区域的样本中多氯联苯浓度高于其他地点的样本。大多数样本中的滴滴涕和多氯联苯水平表明，韦罗海滩和皮尔斯堡之间的印度河水道受这些化合物的污染程度较低。
