摘要
以锦州湾表层沉积物中重金属元素为研究对象,采用潜在生态风险指数法评价了锦州湾表层沉积物重金属元素引起的潜在生态风险,同时,运用生物效应数据库法导出的沉积物质量基准(SQGs)(ERL/ERM)对沉积物重金属的生物毒性效应进行了研究。结果表明,潜在生态风险指数法与沉积物质量基准评价方法所反映的结果具有一致性,但也存在一定差异,2种评价方法各有特色,可以相互补充和借鉴。同时,评价结果表明,研究区域处于低潜在生态风险,未表现出明显生态危害性,主要生态风险区域集中在靠近葫芦岛锌厂和五里河入海口的部分海域。
The heavy metal contaminations in surface sediments from Jinzhou Bay,Liaoning province was assessed by the SQGs(ERL/ERM) indices and the potential ecological risk assessment(Haknson) for the ecological risk in the area,and the SQGs indices were developed from a biological effects database for sediments for potential adverse biological impacts.The results showed that the assessment of the two methods were similar results,each evaluation method with own characteristics,and could be the evidence for each other.There were low potential ecological risk,and no ecological adverse factors in the involved area,near where the ecological risk area was observed in the Huludao Zn-making factory and the mouth of Wuli River.
