摘要
使用ICP-MS和原子荧光仪对中山市长江水库取水口附近表层沉积物中重金属进行分析,并对其污染和生态风险进行评价。地质累积指数法结果表明,汞、砷、镍、铜、铬为无污染,锌和铅为轻度污染,镉为偏中度污染;潜在生态风险指数法显示,砷、铬、镍、铜、锌、铅等的潜在生态风险程度为轻微,汞为中等,镉为较强。
ICP-MS and atomic fluorescence were used to analyze heavy metals in surface sediments near the intake of the Changjiang Reservoir in Zhongshan City.The pollution and ecological risks of the heavy metals were evaluated.The results of the geo-accumulation index showed that Hg,As,Ni,Cu,Cr were no pollution,Zn and Pb were light pollution,and Cd was moderate pollution;The potential ecological risks of As,Cr,Ni,Cu,Zn and Pb were slight,Hg was medium,and Cd was strong.
