摘要
根据2004—2006年辽宁省近岸海域的生物和沉积物质量监测,对该区域的环境质量状况和趋势作出分析和评价。结果表明,辽宁省近岸海域环境质量呈逐年恶化的态势,尤其是重金属Pb和Cd残留量超标较严重,2006年生物体重金属Pb、As和沉积物As残留量超标率接近100%。
The status and trend of the environmental quality were evaluated by the biology and sediment survey in Liaoning inshore area from 2004 to 2006. The results showed that the environment in the Liaoning coast was worsening year by year, especially the contents of Pb and Cd. In 2006, the exceeding rates of Pb and Se in the organism and Se in the sediment approached to 100%.
