Purpose

In this study the aim was to analyze the seasonal concentration, groundwater quality, usage areas and arsenic-related health risk of major ions and heavy metals in groundwater samples collected from the Salda Lake basin.

Methods

In this study, 42 groundwater samples were collected from springs and wells in dry and wet seasons in 2015. Hydrogeochemical evaluations were made using different diagrams such as Piper and Gibbs diagrams. Groundwater quality was determined by the water quality index method (WQI) and different diagrams. Finally, health risk assessments related to arsenic were performed.

Results

The dominant water types are Mg-Ca-HCO₃ and Mg-HCO₃ in the wet season and Mg-HCO₃ and Mg-HCO₃-CO₃ in the dry season. According to calculated WQI values ranged from 24.14 to 56.93 in the wet season ranged from 25.27 to 145.87 in dry season. This situation indicates that the quality of water samples is mostly good both seasons. As_T concentrations were between 2.1–6.3 μg/L in the dry season and 2.9–10.5 μg/L in the wet season. The risk of developing cancer due to arsenic exposure in healthy adults or children is very low. But arsenic has high non-carcinogenic and carcinogenic potentially harmful effect in the study area. In addition, water samples are not appropriate for use as drinking water in terms of fertilizers and trace element concentrations. Also, MH will be an important problem in waters that will be used as irrigation water. The use of some samples is not recommended as it may cause crusting on metal surfaces in industrial areas.

Conclusions

According to the results obtained, the quality of groundwater in the study area should be monitored and the usage areas should be determined accordingly.

萨尔达湖盆地（布尔杜尔/土耳其）地下水质量和可用性以及与砷污染相关的健康风险评估

 目的

本研究的目的是分析萨尔达湖流域地下水样本中主要离子和重金属的季节性浓度、地下水质量、使用区域以及与砷相关的健康风险。

 方法

本研究在2015年旱季和雨季从泉水和井中采集了42个地下水样品。使用Piper图和Gibbs图等不同图进行水文地球化学评价。地下水质量通过水质指数法（WQI）和不同的图表来确定。最后，进行了与砷相关的健康风险评估。

 结果

雨季主要水类型为 Mg-Ca-HCO ₃和 Mg-HCO ₃ ，旱季主要水类型为 Mg-HCO ₃和 Mg-HCO ₃ -CO ₃ 。据计算，WQI值雨季为24.14至56.93，旱季为25.27至145.87。这一情况表明，两季水样水质总体良好。旱季_T浓度为 2.1–6.3 μg/L，湿季 T 浓度为 2.9–10.5 μg/L。健康成人或儿童因接触砷而患癌症的风险非常低。但砷在研究区具有较高的非致癌和致癌潜在危害作用。此外，从肥料和微量元素浓度来看，水样不适合用作饮用水。此外，MH 将成为灌溉用水的一个重要问题。不建议使用某些样品，因为它可能会导致工业区域的金属表面结痂。

 结论

根据监测结果，对研究区地下水水质进行监测，并确定使用区域。
