摘要
在焦岗湖湖体布设13个采样点,测定水体7种元素含量,利用主成分分析和因子分析探究其分布特征,并基于水环境健康风险评价模型对7种元素存在的健康风险进行评价。结果表明,焦岗湖水体中7种元素测定值符合《地表水环境质量标准》(GB3838—2002)标准要求;元素Pb、Cr、As、Mn、Cd来源于人为污染,Ni、Cu来源于自然资源;焦岗湖水体入湖口存在总健康风险,而单一重金属不存在健康风险,总健康风险值整体呈现西半湖高于东半湖的趋势。
The concentration of seven elements from thirteen sampling points in Jiaogang Lake were determined, the distribution characteristics were studied by principal component analysis and factor analysis methods, and the health risks of these elements were evaluated based on the water environment health risk assessment model. The results showed that the concentration of these elements in Jiaogang Lake met the requirements of Environmental Quality Standard for Surface Water (GB 3838-2002). Pb,Cr,As,Mn and Cd were derived from man-made pollution. Ni and Cu were from nature resource. There was total health risk in the inlet of Jiaogang Lake, while no health risk existed in single heavy metal. The total health risk in the west-half of the lake was higher than that in the east-half.
