| 摘要: |
| 有机氯农药(DDT，BHC)和多氯联苯(PCBs)是人工合成的有机氯化合物。它们的化学性质稳定，在环境中能持久地残留并不易受环境中各种因素的作用而降解，它们在生物体内的累积和生物链中的浓缩已构成对人类和生态系统的潜在危害，早已引起世界各国的关注，并公认为全球性的环境污染物。许多国家的学者对不同海区、各大洋海水、沿岸海水、沉积物以及海洋生物体内的DDT, BHC, PCBs作了广泛深入的调查研究(Elear, 1976; Edwand et al, 1975; Ehrhardt, 1981; Harvey, 1973; Osterroht, 1977;Robert, 1976)。我国对近海海域有机氯农药污染状况作过一些调查，但对多氯联苯未见有过报道。、1980年8月作者在渤海湾采集了26个站位的海水样品，22个站位的沉积物样品和8个毛蚶(Arasubcrenata Lischke)样品，分析了其中DDT, BHC, PCBs的含量水平，并对其在渤海湾中的分布特征作了初步探讨。 |

| Abstract: |
| Determination of the level of organochorined pesticides and polychlorinated biphenyls in seawater， organisms and sediment in Bohai Bay showed that the concentrations of total BHC, total DDT and PCBs. were in the range of 55.25-328.25 ng/L, 1.28-6.17 ng/L and 3.50--6.70 ng/L in seawater; 5.58-36.24 ng/g， 0.27-3.15 ng/g and 2.17-8.80 ng/g in sediments; and 14.43-69.51 ng/g, 1.80-3.70 ng/g and 4.30-8.80 ng/g in organisms, Arca subcrenata Lischke, respectively. .
Investigation of the distribution features of DDT, BHC and PCBs in seawater, sediments. and organisms in Bohai Bay showed that pollution of DDT, BHC and PCBs. were not serious. |
