【摘要】 以中国大陆第一个砷中毒病区新疆奎屯地区为研究区域,测定了该地区95个水样中砷、氟的含量和主要水化学因子。结果表明:奎屯河地表水为低砷低氟水,地下水中高砷水占61.36%,高氟水占28.41%。该地区高砷高氟地下水主要分布在奎屯河流域下游的西北部和中北部。高砷、高氟岩石是奎屯河流域地下水中砷、氟的原生来源,水文地质环境和强烈的蒸发使地下水中砷和氟逐渐富集,地下水的碱性和还原环境有利于含水层中砷和氟的释放。更多还原

【Abstract】 It was analyzed that the content of arsenic and fluorine and main chemical factors of 95 water samples in Kuitun River which was the first reported area with endemic arsenic poisoning disease identified in mainland China.The results show that the content of arsenic and fluorine were low in the surface water of Kuitun River.On the contrary,the contents of them were high in the groundwater of this area,which was 61.36% and 28.41% for arsenic and fluorine,respectively.The groundwater with high arsenic and fluorine mainly distribute in the northwest and north-central part of Kuitun River Basin.The arsenic and fluorine in ground water mainly come from strata or rock which contain highly elements of arsenic and fluorine.The hydro-geological environment and intensive evaporation gradually enriched arsenic and fluorine in the groundwater.In addition,alkaline and strong reduction environment in the groundwater were contributed to the release of arsenic and fluorine in the aquifer.更多还原
