【摘要】 根据重金属的生物地球化学特征 ,从沉积学角度 ,利用辽东湾东部浅水区 3次环境调查数据 (1988、1997、1999) ,进行沉积物重金属潜在生态危害评价。研究结果表明 ,辽东湾浅水区沉积物污染长期以来较小 ,属于轻微生态危害 ,产生危害的主要重金属元素是汞和镉更多还原

【Abstract】 Based on data from four environmental investigations(1988,1993,1997,1999),the potential ecological risk of heavy metal of sediments has been assessed.The results show that the contamination level of sediments in Liaodong bays shallow waters is light.The main factors caused ecological hazard are mercury and cadmium.更多还原
