| 摘 要： | 本文分析了粤北星子河12种水生生物样品中Cd、Cr、Cu、Pb、Ni和Zn等6种金属元素的含量水平。利用综合污染指数法和目标危害系数法对水生生物中重金属的污染特征及其健康风险进行评价。结果表明:不同水生生物对重金属的富集程度存在明显差异,重金属的含量水平从低到高顺序依次为:CdNiPbCrCuZn;鱼类富集重金属明显低于贝类。在贝类样品中,Cr、Pb和Zn的含量均出现超标现象。鱼类重金属综合污染指数低于1,属于微污染;而田螺重金属综合污染指数大于1,属于轻度污染水平。不同鱼类中重金属的复合健康危害系数(TTHQ)均小于1,且每周评估摄入量(EDI)均远低于暂定每周允许摄入量(PTWI),居民通过鱼类摄入重金属的健康风险较低;田螺中重金属对人的复合健康危害系数大于1,长期食用田螺存在较高的健康风险,风险较高的重金属元素为Cr、Pb和Zn。

| Abstract: | The concentrations of 6 kinds of heavy metals, including Cd, Cr, Cu, Pb, Ni and Zn, were detected in the muscles of twelve aquatic species from northern Guangdong Province. Their contamination characteristics and health risk were assessed using comprehensive pollution index and Target hazard quotient (THQ). The results showed that the concentrations of heavy metals varied in different aquatic species, and the concentration in increasing order was Cd
