This paper describes the initial investigation of PCB concentrations in four geographical regions (three on the Pacific and one in the Caribbean) of coastal Costa Rica: Bahia Culebra, Golfo Dulce, Golfo de Nicoya, and Limón. Overall total concentrations of PCB were low in all areas except around the port of Golfito (Golfo Dulce). Overall average concentration is 2.80 ng/g dw, with a standard deviation of 2.75. The low concentration could be due to lack of contamination or the subsequent degradation in the warm climate, or the low sorptive capacity of the sediment. Further investigation is ongoing.
本文描述了对哥斯达黎加沿海四个地理区域（太平洋沿岸三个区域和加勒比地区一个区域）多氯联苯浓度的初步调查，这四个区域分别是巴伊亚库莱布拉、杜尔塞湾、尼科亚湾和利蒙。除戈尔菲托港（杜尔塞湾）周边地区外，所有区域的多氯联苯总浓度均较低。总体平均浓度为2.80纳克/克干重，标准偏差为2.75。浓度较低可能是由于缺乏污染、温暖气候下的后续降解或沉积物的低吸附能力。进一步的调查正在进行中。
