摘要
Using atomic fluorescence photometer(XGY-1011A ) and multifunctional polarograph (HY-1F ), the contents and distribution of heavy metals (Hg, Cu, Pb, Zn and Cd) in surface seawater were studied. The pollution level was evaluated with water quality index (WQI) model. The result showed that the contents of Hg, Cu, Pb, Zn and Cd in surface seawater ranged from 0.009~0.050, 0.9~4.3, 0.4~1.4, 1.6~19.0, 0.1~0.7 μg/dm3, and averaged 0.025, 2.4, 0.8, 9.4, 0.2 μg/dm3, respectively. The contents diminished from Pinqinghu Bay towards Shanwei Port.
