摘　　要：采用电感耦合等离子质谱法检测淮河(安徽段)水体中Ni、Pb、Cr、Cd、As、Cu、Zn、Mn七种重金属含量,并分析重金属的含量、分布特征及潜在风险评价。结果表明:重金属Ni、Pb、Cr、Cd、Cu、Zn、Mn含量均值分别为0.52μg/L、0.45μg/L、2.81μg/L、0.07μg/L、2.50μg/L、2.56μg/L、4.69μg/L;其中Pb和Cd低于2017年淮河淮南段,Cu和Zn高于2017年淮河淮南段,元素Pb、Cr、Cd和Cu均低于2010年淮河安徽段,其中Cu和Zn仍需重点关注。根据两种指数法的评价结果显示:除了元素Cd外,其余六种重金属元素在整个采样区的平均值与最大值均远小于40,呈现低风险水平,元素Cd仅有一个采样点呈现轻度污染,该采样点为T13马城镇。由此可见,元素Cd为主要污染因子,T13马城镇存在较大风险,需进一步关注。Inductively coupled plasma mass spectrometry was used to detect the contents of Ni,Pb,Cr,Cd,As,Cu,Zn and Mn in the Huaihe River(Anhui Section),and the content,distribution characteristics and potential risk assessment of heavy metals were analyzed.The results showed that the average contents of heavy metals were 0.52μg/L,0.45μg/L,2.81μg/L,0.07μg/L,2.50μg/L,2.56μg/Land 4.69μg/L,respectively.Among them,Pb and Cd were lower than those in the Huainan section of the Huaihe River in 2017,Cu and Zn were higher than those in the Huainan section of the Huaihe River in 2017,and the elements Pb,Cr,Cd and Cu were lower than those in the Anhui section of the Huaihe River in 2010.According to the evaluation results from two index methods,except for the element Cd,the average and maximum values of the other six heavy metals in the whole sampling area were much less than 40,showing a low-risk level,and only one sampling point of the element Cd showed mild pollution,which was T13 Macheng Town.It can be seen that the element Cd is the main pollution factor,particularly in T13 Macheng Town,which needs further attention.
