Abstract

Fluoride (F) in the environment has appealed the contemplation of numerous researchers across the globe; which is an essential element for human health within certain limits and toxic beyond that. Therefore, knowledge of variation of F is thus a necessity for taking preventative measures. In view of this, 60 samples were collected to study health risk assessment from Ambadongar area representing geological diversities. The F concentration in the study area varies from 0.43 to 4.25 mg/L with an average of 1.5 mg/L. From which 41% of wells show F concentration greater than the recommended limit (GRL) of 1.25 to 2.25 mg/L from Basalt, Limestone and alkaline rocks and 43% excess than recommended limit (ERL) of more than 2.25 mg/L from Nephelinite lithology. Out of these, 22% wells are from Sandstone, 7% from Basalt, 26% from limestone and 4% from Carbonatite breccia show F concentration above GRL, whereas 14% from Basalt, 29% from Limestone and 14% from Carbonatite Breccia display that F concentration to be exceeding ERL. Most of the wells show values of total hazard quotients exceeding unity which suggests the possibility of health risk hazard. The hydrogeochemical analysis supports the prevalence of F and its effect in form of dental fluorosis in the study area. It is envisioned that in addition to the people already affected large fraction of population is at potential risk.

印度 Ambadongar South Gujarat 地质多样性周围地下水中氟化物的健康风险评估和流行率

摘要

环境中的氟化物 (F - ) 引起了全球众多研究人员的关注。这是在一定限度内对人类健康必不可少的元素,超出该限度是有毒的。因此,了解 F -的变化是采取预防措施的必要条件。鉴于此,从代表地质多样性的 Ambadongar 地区收集了 60 个样本以研究健康风险评估。研究区的 F -浓度从 0.43 到 4.25 mg/L 不等,平均为 1.5 mg/L。其中 41% 的井显示 F -浓度大于玄武岩、石灰岩和碱性岩中 1.25 至 2.25 mg/L 的推荐限值 (GRL),比霞石岩性中超过 2.25 mg/L 的推荐限值 (ERL) 高 43%。其中,22% 的井来自砂岩、7% 来自玄武岩、26% 来自石灰岩和 4% 来自碳酸岩角砾岩显示 F 浓度高于 GRL,而 14% 来自玄武岩、29% 来自石灰岩和 14% 来自碳酸岩角砾岩显示F 浓度超过 ERL。大多数井的总危险商值超过 1,这表明存在健康风险危害的可能性。水文地球化学分析支持 F 的流行-及其对研究区氟斑牙形式的影响。预计除了已经受到影响的人之外,还有很大一部分人口处于潜在风险中。
