Access to clean water has gained great importance, especially in urban areas, in connection with drought within the framework of climate change. This study was carried out with hydrogeochemical investigation in a district of İzmir, the 3rd largest city of Turkiye, which contains economic natural ore deposits (Sb, Hg, and Pb-Zn). The heavy metal content of groundwater has great importance in and around the ore deposits for health risk assessments (HRA) and water quality index (WQI) interpretations. Groundwater samples in the study area were taken from different units such as gneiss, marble, schist, and alluvium. The electrical conductivity of water varies between 466 and 2720 μS/cm. The waters are of NaCaHCO3 and CaNaHCO3 water types. Silicate and carbonate weathering were seen in the waters taken from gneiss/schist and marble/alluvium, respectively. Al, Ni, and Sb values of groundwater exceeded the drinking water standards. Sb concentrations can reach 967 ppb, and all waters are oversaturated with Sb(OH)3. It is thought that Sb mixes with groundwater along faults from mineralization zones. According to the WQI, the groundwater is not suitable for drinking. If the presence of ore deposits is neglected in the WQI, water that is dangerous for drinking is incorrectly considered ″drinkable″. The HRA was calculated for Al, Cu, Fe, Mn, Ni, Sb, and Zn parameters. The hazard coefficient of Sb is more than 1 for adults and children. The most striking effect of Sb compounds is that they disrupt the heart rhythm and cause irreparable damage to the nervous system.

利用水质指数和健康风险评估评估定居区受地质影响的地下水锑污染：以土耳其伊兹密尔基拉兹盆地为例
与气候变化框架内的干旱有关，获得清洁水变得非常重要，尤其是在城市地区。本研究是在土耳其第三大城市伊兹密尔的一个地区进行的水文地球化学调查，该地区包含经济的天然矿床（Sb、Hg 和 Pb-Zn）。地下水的重金属含量对于矿床及其周围的健康风险评估 (HRA) 和水质指数 (WQI) 解释具有重要意义。研究区的地下水样品取自片麻岩、大理岩、片岩和冲积层等不同单元。水的电导率在 466 和 2720 μS/cm 之间变化。水域为NaCaHCO 3和CaNaHCO 3水类型。在从片麻岩/片岩和大理石/冲积层中提取的水中分别观察到硅酸盐和碳酸盐风化。地下水Al、Ni、Sb值超标。Sb 浓度可达 967 ppb，并且所有水域都被 Sb(OH) 3过饱和. 据认为，锑沿着矿化带的断层与地下水混合。根据 WQI，地下水不适合饮用。如果在 WQI 中忽略了矿床的存在，则饮用危险的水会被错误地认为是“可饮用的”。HRA 是针对 Al、Cu、Fe、Mn、Ni、Sb 和 Zn 参数计算的。Sb对成人和儿童的危害系数大于1。锑化合物最显着的作用是扰乱心律并对神经系统造成无法弥补的损害。
