摘要

摄入低于安全限度的氟会导致龋齿,而高浓度的氟会导致氟中毒,从而可能损害人体系统。影响水中氟浓度的一个地质因素是水流经过的岩石类型,包括花岗岩及其风化产物。该地区位于主要由花岗岩组成的丹绒布库地层(Tandjungbuku Formation)内,其中有几个地区获得了硅砂等商品的采矿经营许可证(IUP)。这项研究是对采矿活动、采矿后和工业区发展的一种缓解措施。一个预期的影响是研究区域内氟化物浓度的增加,其来源既有自然地质过程,也有人类活动。调查包括地质绘图、岩相分析、XRD 和 XRF 分析。在 Resang Tandjungbuku 村的水井中对地表水和地下水进行了取样。研究区域由两个岩石单元组成:作为非含水层的花岗岩和作为游离含水层的冲积层。岩相分析发现了与氟化物有关的矿物,如斜长石、闪长石和黑云母。X 射线衍射分析也证实了这一点,其中存在生物黄铁矿、褐铁矿和高岭土矿物。XRF 结果显示,花岗岩石中的氟含量为 0.23% 或 2300 ppm,进一步证实了花岗岩是氟的来源。对地表水中氟化物的分析表明,其值从 0.01 到 4.24 毫克/升不等,而地下水中的氟化物值始终为 0.01 毫克/升。

Identification and distribution of fluoride in Singkep Island, Lingga Regency, Riau Islands
The consumption of fluoride below the safe limit can result in dental caries, while high concentrations can lead to fluorosis, which can potentially impair the body's systems. One geological factor that influences the concentration of fluoride in water is the type of rock through which the water passes, including granite and its weathering products. The area is located within the Tandjungbuku Formation, which is predominantly composed of granite rock and contains several areas with Mining Business Permits (IUP) for commodities such as silica sand. This research serves as a form of mitigation in response to mining activities, post-mining, and the development of an industrial area. One anticipated impact is an increase in fluoride concentration in the research area, originating from both natural geological processes and human activities. The investigation involved geological mapping, petrographic analysis, XRD, and XRF analysis. Water sampling was conducted for both surface water and groundwater from wells in Resang Tandjungbuku Village. The research area consists of two rock units: granite, which acts as a non-aquifer layer, and colluvial deposits, which function as a free aquifer. Petrographic analysis identified minerals associated with fluoride, such as plagioclase, amphibole, and biotite. This was supported by XRD analysis with the presence of biotite, muscovite and kaoline minerals. XRF results revealed fluoride values in granite rock at 0.23% or 2300 ppm, further confirming granite as a source of fluoride. Analysis of fluoride in surface water showed values ranging from 0.01 to 4.24 mg/L, while groundwater consistently had a value of 0.01 mg/L.
