【摘要】 采用X-射线荧光法分析了淮河沉积物中重金属的污染状况,并根据沉积学原理和环境化学行为特点,应用地积累指数法对淮河沉积物中重金属污染水平进行了评价研究。结果表明,淮河沉积物中有一定的重金属污染,其中Cu,Pb,Cr,Ni的污染水平较高。更多还原

【Abstract】 Sedimentary heavy metal pollution of the Huaihe River was analyzed through X-ray fluorescence monitor.Based on the sedimentology and environmental behavior characteristics of heavy metals,the index of geo-accumulation (I_geo)is applied to evaluate the heavy metal pollution in the sediments of the Huaihe River.The results show that the heavy metal pollution in the Huaihe River is serious to some extent.Among them,the dominant contaminants are Cu,Pb,Cr and Ni.更多还原
