Contamination of arsenic and fluoride in drinking water reservoirs is a serious health issue in the Sibi district, Balochistan, Pakistan. The contamination has already been affecting a large population of the district. Dental fluorosis and dermatitis are the most common reported illnesses in the area. This study focused on the evaluation of the root causes and pathway by which it reached to the body. Questioner analysis, simple examination, and pictorial representation were used to study the prevalence of diseases caused by As and F. People of the Sibi district were found to consume both surface and groundwater, which were highly contaminated with arsenic and fluoride. The saturation index, ranging from 1 to 7, showed high enrichment of contaminants in both types of water. Geochemical calculations and the sodium absorption ratio were evaluated. High values of the saturation index of different salts showed high saturation of salts in water. The principal component analysis grouped the data into three clusters, showing that the surface water has no resemblance with the control water. High degree of contamination was observed for most of the samples, whereas, some samples of ground water were closed to the control group; a group of samples within WHO limits. The correlation studies and other calculations also revealed that the F and As reached lethal limits in the drinking water and thus caused severe health damage to the local area population. The diseases found in the area are fluorosis, keratosis, dermatitis, and melanosis.

采矿活动导致饮用水中的氟化物和砷污染及其对当地人口的影响。

在巴基斯坦Bal路支斯坦的锡比区，饮用水水库中砷和氟化物的污染是一个严重的健康问题。污染已经影响到该地区的大量人口。氟中毒和皮炎是该地区最常见的报告疾病。这项研究的重点是评估其到达人体的根本原因和途径。通过提问者分析，简单检查和图形表示法研究了As和F引起的疾病的患病率。发现Sibi地区的人们既消耗地表水，又消耗地下水，地下水被砷和氟化物高度污染。饱和指数在1到7之间，表明两种水中的污染物高度富集。评估了地球化学计算和钠吸收率。不同盐的饱和指数的高值表明水中盐的高饱和度。主成分分析将数据分为三个类，表明地表水与对照水没有相似之处。大多数样品都观察到高度污染，而对照组的一些地下水样品是封闭的。在WHO限制范围内的一组样本。相关研究和其他计算还表明，F和As达到饮用水中的致死极限，从而对当地人口造成了严重的健康损害。该地区发现的疾病是氟中毒，角化病，皮炎和黑变病。表明地表水与对照水没有相似之处。大多数样品都观察到高度污染，而对照组的一些地下水样品是封闭的。在WHO限制范围内的一组样本。相关研究和其他计算还表明，F和As达到饮用水中的致死极限，从而对当地人口造成了严重的健康损害。该地区发现的疾病是氟中毒，角化病，皮炎和黑变病。表明地表水与对照水没有相似之处。大多数样品都观察到高度污染，而对照组的一些地下水样品是封闭的。在WHO限制范围内的一组样本。相关研究和其他计算还表明，F和As达到饮用水中的致死极限，从而对当地人口造成了严重的健康损害。该地区发现的疾病是氟中毒，角化病，皮炎和黑变病。相关研究和其他计算还表明，F和As达到饮用水中的致死极限，从而对当地人口造成了严重的健康损害。该地区发现的疾病是氟中毒，角化病，皮炎和黑变病。相关研究和其他计算还表明，F和As达到饮用水中的致死极限，从而对当地人口造成了严重的健康损害。该地区发现的疾病是氟中毒，角化病，皮炎和黑变病。
