摘　　要：于2007年春季和秋季对我国北黄海海域进行调查,采取溶剂萃取-原子吸收分光光度法对海水中溶解态重金属Cu,Pb,Zn,Cd进行了分析。结果表明,北黄海表层海水中溶解态重金属的含量呈现出沿岸海区高,中央海区低,浓度自近岸向远海逐渐减少的趋势,受沿岸人类活动影响较为明显。除秋季个别站点的Pb,北黄海表层海水重金属含量均未超过国家一类海水水质标准,水质良好。During the investigation in China＇s North Yellow Sea Area in the spring and autumn of 2007, 76 surface sea water samples were taken for soluble heavy metals（Cu, Pb, Zn and Cd） analyses with dissolvent extraction-atomic absorption spectrophotometry method. It could be seen from the analytical results that concen- trations of soluble heavy metals decreased from littoral sea area to central sea area, which was obviously an influence of human activities. Except for Pb concentration values at some particular stations, most concentration values of heavy metals in the spring and autumn of 2007 did not exceed those of the First-Classed Seawater Quality Standard of China, which indicated a pretty good water quality in NYS Area.
