对夏季渤海湾南部海域表层海水中的多氯联苯(PCBs)、有机氯农药(OCPs)和多环芳烃(PAHs)的污染状况进行了调查。结果表明,PCBs、六六六(HCHs)、滴滴涕(DDTs)和PAHs的含量分别为0.09～0.22μg/L、0.05～0.13μg/L、0.07～0.21μg/L和145.8～556.1 ng/L。沿岸的工业废水排放等陆源输入可能是渤海湾中PCBs和OCPs的重要来源;而石油污染则是该海域PAHs的主要来源。
Pollution levels of polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs) and polycyclic aromatic hydrocarbons (PAHs) in surface seawater in the southern Bohai Gulf in summer were investigated. The results showed that the contents of PCBs, HCHs, DDTs and PAHs were 0.09 ~ 0.22μg / L, 0.05 ~ 0.13μg / L, 0.07 ~ 0.21μg / L and 145.8 ~ 556.1 ng / L, respectively. The input of terrestrial sources such as industrial wastewater along the coast may be an important source of PCBs and OCPs in the Bohai Bay, while petroleum pollution is the main source of PAHs in this area.
