The drinking water of Naranji village and surrounding areas of the NorthWest Frontier Province (NWFP), Pakistan, was analyzed for its fluoride content. The fluoride content of water samples from the springs in the Naranji village goes up to 13.52 mg kg(-1), which exceeds the permissible limit (1.5 mg kg(-1)) set by the World Health Organization (WHO). This study explores the source of fluoride contamination and attributes it to the alkaline rocks of the Ambela granitic complex and the Koga complex. The low-lying areas towards the south have a fluoride content within the permissible limit. The Naranji area therefore needs urgent remedial measures.
对巴基斯坦西北边境省（NWFP）纳兰吉村及周边地区的饮用水进行了氟含量分析。纳兰吉村泉水样本中的氟含量高达13.52毫克/千克，超过了世界卫生组织（WHO）设定的允许限值（1.5毫克/千克）。本研究探究了氟污染的来源，并将其归因于安贝拉花岗岩杂岩体和科加杂岩体的碱性岩石。南部的低洼地区氟含量在允许限值内。因此，纳兰吉地区需要采取紧急补救措施。
