珠海码头内铜污染现状及生态风险分析

摘要:
以珠海码头作为调查船舶防污漆使用影响的对象,分析了珠海周边海域码头内表层沉积物与海水中的重金属含量,以Cu元素为讨论重点,对其进行污染程度与潜在生态危害的评估。结果表明,码头内表层沉积物中Cu含量明显高于码头外沉积物,离市区较近的香洲码头和金沙滩码头内沉积物受到中等至较高程度的Cu污染,海岛东澳岛码头海水易流通,因此受污染程度较低。使用Hakanson生态危害指数法对沉积物进行评估的结果为低潜在生态危害,但码头内海水中Cu元素含量已高于生态安全限值。

Analysis on Current Status and Ecological Risk of Copper Pollution in Zhuhai Ports

Abstract:
Zhuhai ports were chosen as the objects to assess the effect on using antifouling paint from boats. The heavy metal contents of surface sediment and the seawater in Zhuhai ports were studied, with a focus on copper element. The pollution level and the potential ecological risk were assessed. The results showed that the surface sediment in the ports, such as the sediment from the Xiangzhou and Jinsha ports, which were close to the urban area, was exposed to middle to high level of copper pollution. Whereas the surface sediment outside the marine, such as the sediment from the Aodao Marina off the east island, was exposed to low level of copper pollution due to water circulation. The potential ecological risk was low as evaluated by Hakanson ecological risk index, but the copper concentration in sea water exceeded the ecological safety limit.
