摘　　要：对采集自淮河中游五河段的沉积物和淡水贝类样品,利用ICP-AES和GC-MS进行重金属和多环芳烃分析,结果表明砷、铅、铬超标,多环芳烃在沉积物中的含量最多,研究区域的PAHs污染严重.这些有毒污染物可能来自上游工业区的淮南和蚌埠段,在贝类软体中有较高含量.因此,这些污染物有可能经食物链富集于其他生物体内,对水生态系统产生损害,进而影响到水产品食用安全,应进一步加强研究,提出防治对策.The freshwater mussels and sediments were collected from Wuhe Section of Huaihe River outside industrial area. The samples were assayed by ICP - AES and GC - MS. These methods used in detecting heavy metals and PAHs. The results indicated that As, Pb and Cr concentrated in sediments and were much higher in concentration in mussels. The contents of PAHs were relatively higher in sediments and freshwater mussels. It is suggested that heavy metals and PAHs from industrial area already influenced the freshwater water ecosystem in Wuhe section of Huaihe river, then may influence safety of freshwater products.
