摘要
调查了自山东日照至长江口范围内江苏黄海海域18个站位的野生鱼类和甲壳类经济动物体内的污染物水平,监测项目包括:重金属Cu,Pb,Cr,Cd,Hg,总As和石油烃,并对调查结果进行了污染负荷评价。从地域分布来看长江口和吕四港的整体污染水平较高,污染负荷指数为0.35;海州湾和东沙污染水平相当,污染负荷指数为0.25;东沙Cd污染较突出。从生物种类来看鱼类和甲壳类的总As含量较高;大部分生物均发现中度石油烃污染;甲壳类生物体内Cd含量濒临超标限;其余各类生物重金属含量均远低于标准值。
We investigated contamination levels of heavy metals（Cu, Pb, Cr, Cd, As, Hg） and petroleum hydrocarbon in marine organisms, fishes and crustaceans, in the Huanghai Sea area of Jiangsu Province. Single-Factor Pollution Index and integrated Pollution Load Index were used to assess the contamination levels in fishes and crusta- ceans. We found that the pollution level in the Yangtze River estuary and Lvsi port was relatively high with a pollution load index of 0.35, while the pollution load index of Haizhou estuary and Dongsha area was about 0.25. Cd contamination in the Dongsha area was relatively severe. Relatively high levels of total As were found in both fishes and crustaceans. Most organisms suffered from moderate petroleum hydrocarbon pollution. Cd levels in crustaceans were close to the food safety standard; in contrast, levels of Cu, Pb, Cr and Hg were far below the standard.
