根据2013年夏（8月）、秋季（10月）对乳山湾附近海域表层海水重金属的调查资料，分析了该海域溶解态重金属Cu、Pb、Zn、Cd的时空分布特征，并对其进行了污染评价。结果表明，海域表层溶解态重金属的含量均表现为Zn＞Cu＞Pb＞Cd ，夏季的平均含量高于秋季。浓度高值集中在沿岸海域，受人类活影响明显。溶解态重金属的浓度在夏、秋两季均达到了国家II类海水水质标准，说明该海域海水水质状况良好。
根據2013年夏（8月）、鞦季（10月）對乳山灣附近海域錶層海水重金屬的調查資料，分析瞭該海域溶解態重金屬Cu、Pb、Zn、Cd的時空分佈特徵，併對其進行瞭汙染評價。結果錶明，海域錶層溶解態重金屬的含量均錶現為Zn＞Cu＞Pb＞Cd ，夏季的平均含量高于鞦季。濃度高值集中在沿岸海域，受人類活影響明顯。溶解態重金屬的濃度在夏、鞦兩季均達到瞭國傢II類海水水質標準，說明該海域海水水質狀況良好。

Based on the data of surveys during summer (August) and autumn(October) in the surface seawaters near Rushan Bay in 2013 ,the distribution characteristics of the heavy metal (Cu、Pb、Zn、Cd) were analyzed ,and evaluated the level of pollution .The results showed that the concentrations of the dissolved heavy metals were characterized by Zn > Cu> Pb> Cd ,and the average of concentration in summer was higher than in autumn .The high concentration value was concentrated in the coastal sea‐waters ,which was obviously influenced by human activities .The concentration values of the dissolved heavy metals in the summer and autumn of 2013 did not exceed those of the Second -Classed Seawater Quality Standard of China ,which indicated the quality of the seawaters near Rushan Bay was good .
