Constant drinking water monitoring schemes are necessary because hazardous substances tend to enter water bodies through geodetic and anthropogenic sources. The main goal of this study was to evaluate the human health risk assessment posed by high fluoride and iron concentration in tap water used for domestic activities and consumption. In this study, the concentration of fluoride in tap water varied at different locations, ranging from 0.48 mg/L to 1.84 mg/L with an average value of 1.23 mg/L while that of iron ranged from 0.02 to 2.96 mg/L. The cluster analysis displayed three popular groups in which the samples can be classified. The non-carcinogenic risk was determined with defined methods outlined by US EPA considering dermal and ingestion pathways. Total Hazard Index greater than 0.8 for fluoride consumption in the analyzed locations was obtained from location R16, R17, R15, R4, and R6.
持续的饮用水监测计划是必要的，因为有害物质往往通过地质和人为来源进入水体。本研究的主要目标是评估生活活动和消费所使用的自来水中高氟和高铁浓度对人体健康造成的风险评估。在本研究中，不同地点的自来水中氟化物浓度各不相同，范围为0.48毫克/升至1.84毫克/升，平均值为1.23毫克/升，而铁的浓度范围为0.02至2.96毫克/升。聚类分析显示样本可分为三个常见组。采用美国环境保护局（US EPA）概述的既定方法，考虑皮肤接触和摄入途径，确定了非致癌风险。在分析的地点中，R16、R17、R15、R4和R6地区的氟化物消费总危害指数大于0.8。
