摘要
目的对该地区2015年农村饮用水中碘、砷、氟含量进行检测和分析,为防治碘缺乏症、砷中毒、氟中毒提供可供参考的指导意见。方法于2015年,对该地区10个乡镇共89个行政村的饮用水进行采样,共收集500份饮用水样本,对饮用水样本进行检测,测定其中碘、砷、氟的含量。结果 500份饮用水样本中,碘含量不足50μg/L的样本数有5份,占比1%,属缺碘水,其余水样本的碘含量均在正常范围内（50~150μg/L）;所有样本的砷含量均不足0.004 mg/L,均在正常范围内;所有样本的氟含量均不超过0.3 mg/L,均在正常范围内。集中式供水的碘含量明显高于分散式供水（P〈0.05）,氟含量明显低于分散式供水（P〈0.05）,分散式供水中,压把井水的碘含量、氟含量均明显高于敞口井水、江河水、山泉水（P〈0.05）。结论该地区2015年农村饮用水中的砷、氟含量均较为正常,部分饮用水属缺碘水,需加强碘的摄入,并进一步加强该地区农村饮用水工程的建设,扩大集中式供水范围。
Objective To detect and analyze the content of iodine, arsenic and fluoride in drinking water in rural areas in2015, and provide reference for prevention and treatment of iodine deficiency, arsenic poisoning and fluoride poisoning.Methods In 2015, 500 drinking water samples were collected from 89 villages of 10 towns in our region, The drinking water Samples were collected, and the content of iodine, arsenic and fluoride in drinking water samples were determined. Results In 500 drinking water samples, the iodine content which were less than 50 μg/L had five copies, accounted for 1%, which belonged to the water iodine deficiency, the remaining water samples iodine content were in the normal range（50 to 150 μg/ L）;The arsenic levels of all samples were less than 0.004mg/L, all of which were in the normal range; The fluoride content of all samples was not more than 0.3mg/L, all of which were in the normal range. The iodine content of centralized supply water was significantly higher than that of decentralized supply water（P〈0.05）,the fluoride content of centralized supply water was significantly lower than that of decentralized supply water（P〈0.05）, and in the decentralized supply water, the iodine and fluoride content of the pressure well water was significantly higher than that in open wells, river water, spring water（P〈0.05）. Conclusion The content of arsenic and fluorideof drinking water in rural area in 2015 are relatively normal, part of the drinking water is less iodine water, it is necessary to strengthen the iodine intake, and further strengthen the rural area drinking water project construction, expand the scope of centralized supply water.
