【摘要】 在1990-07—1991-12期间,监测了黄渤海沿岸经济贝类体内的污染物残留量,计算了沿岸软体动物体内石油烃含量的本底值为3.47—19.7mg/kg(湿重),用本底值的上限作为评价标准,对沿岸贝类的石油污染状况,按污染程度做了海区划分,结果是大连湾、长江口、锦州湾的经济贝类是石油烃污染严重的区域;从鸭绿江口至大窑湾的北黄海沿岸是未受石油烃污染的最好环境区域。更多还原

【Abstract】 In this paper, the residue of pollutants in economical shellfish along the coast of Huanghai and Bohai Seas during July 1990 and December 1991 was investigated. The background value of concentration of the petroleum hydrocarbons in mollusc along the coast has been calculated. Its overall range is 3. 47—19.7 mg/kg (wet), and upper limit of the background value was utilized as assessment standard for the pollution level of oil in shellfish along the coast, the sea area division on pollution degrees of oil in mollusc was done. The results showed that content of oil in shellfish of Dalian bay and Changjiang River estuary and west Jinzhou bay is higher, and the coast of north Huanghai Sea from Yalujiang River mouth to Dayao bay is lower.更多还原
