【摘要】 2006年10月对天津塘沽潮间带沉积物中的重金属(砷、汞、铜、锌、铅、镉、镍和铬)进行了调查研究,并采用瑞典科学家Hakanson的潜在生态危害指数法对重金属的危害性进行了评价。结果表明,塘沽驴驹河-高沙岭段潮间带属于低度生态危害区,而蛏头沽段为中度危害区。汞是产生生态危害的主要重金属,它对蛏头沽-驴驹河段潮间带构成重度危害,而对高沙岭的危害是轻微的。更多还原

【Abstract】 The heavy metals, such as arsenic, mercury, copper, zinc, lead, cadmium, nickel and chromium, in the sediments of intertidal zone in Tanggu, Tianjin, were studied in Oct. 2006. And Potential Ecological Risk Index Method proposed by Swedish scientist Hakanson had been applied to evaluate the harm of the heavy metals. The results showed that the ecological risk level in Lvju River and Gaoshaling intertidal zone was light, while moderate in the Chengtougu intertidal zone. The main factor causing ecological hazard was mercury. It posed serious risk to Lvju River and Chentougu intertidal zone and low risk to Gaoshaling intertidal zone.更多还原
