摘要
为了探究皖北宿临矿区水质状况,研究氟化物和硝酸盐对矿区周边生活人群产生的健康风险,采集了23组中层地下水样进行测试分析,基于模糊数学法对地下水进行环境质量评价,运用主成分尝试进行了源解析,并对不同人群开展了健康风险评价。结果表明:宿临矿区中层地下水F-浓度范围为016~216mg/L,NO3-浓度范围为0~851mg/L,水质整体较好,92%水样达到地下水Ⅲ级质量标准(GB/T14848-2017),F-和NO3-等来自含氟矿物萤石的溶解、离子交换及农业活动;健康风险评价结果表明成年人及青少年所受氟化物和硝酸盐风险低,均在安全范围之内。然而,儿童健康风险较高,可能有52%儿童将要承受非致癌的健康风险。
In order to explore the water quality of Sulin mining area in northern Anhui and study the health risks of fluoride and nitrate to the people living around the mining area,23 sets of middle groundwater samples were collected for testing and analysis.The groundwater environmental quality was evaluated based on fuzzy mathematics,the ingredients source was analyzed with the principal component analysis and the health risk assessment was carried out within different populations.The results show that the F-concentration range of the middle groundwater in Sulin mining area is 0.16~ 2.16 mg/L,the N03 concentration range is 0 ~8.51 mg/L,and the water quality is generally good.92% of the water samples meet the groundwater quality standard(GB/T14848-2017),F-,NO3-,etc.come from the Dissolution of fluorine-containing mineral fluorite,ion exchange and agricultural activities;health risk assessment results show that adults and teenagers are exposed to low risks of fluoride and nitrate,and are within the safe range.However,children’ s health risks are higher,52% of children may be exposed to non-carcinogenic health risks.
