淮河安徽段溶解态微量元素污染特征及其健康风险评价
Pollution Characteristics and Health Risk Assessment of Dissolved Trace Elements in the Anhui Section of the Huaihe River
摘要
Abstract
The content of trace elements in 40 water samples from the Anhui section of the Huaihe River were determined by inductively coupled plasma atomic emission spectrometry.The distribution characteristics and pollution sources of 13 dis-solved trace elements in the water body were analyzed by multivariate statistical analysis.The results showed that the median concentration of 13 trace elements in descending order are Mg,Zn,Fe,Mn,Ba,Al,Pb,Cu,Cd,Co,B,Cr,and Ni.The element concentrations were significantly different among different water depths and sampling points.Principal component analysis in-dicates that the trace elements mainly originated from industrial waste,coal combustion,vehicle exhaust,pesticide use,rock weathering and crustal materials.Cluster analysis divides the 10 sampling points into 3 categories,which were respectively af-fected by the inflow of tributaries,sewage power plants and vehicle exhaust,and agricultural activities.The health risk assess-ment indicates that when trace elements were ingested through drinking water,Co,Cd and Pb exert adverse effects on human health;when trace elements were absorbed through the skin,the hazard quotient was less than 1,indicating no significant health risk.关键词
