摘要
以某矿段为例,调查阳山金矿开采前周边地表水水质情况。采集地表水水样14件,研究地表水水化学特征,开展劣质水评价,通过修正内梅罗指数法进行水质污染评价,运用USEPA法开展地表水健康风险评价。早期盗采区内及其下游方向存在多处劣质水,地表水非致癌健康风险和致癌健康风险较大区域全部为金矿盗采区。研究结论显示,矿权内地表水水质污染主要来自于早期盗采。研究成果为保障当地居民身体健康和生态环境提供依据。
The quality of surface water in the surrounding area before the Yangshan gold mining was investigated,and a certain ore section was taken as an example.14 surface water samples were collected to study the hydrochemical characteristics of surface water,and the evaluation of inferior water was carried out.The water pollution was evaluated by the modified Nemelo index method.Surface water health risk assessment was carried out using the USEPA method.There is much inferior water in the early mining area and its downstream direction,and the areas with large non-carcinogenic health risks and carcinogenic health risks of surface water are all gold mining areas.The result shows that the surface water pollution in the ore section is mainly due to early illegal mining.Meaning:This paper provides a basis for protecting the health of residents and the ecological environment.
