In this study, water quality parameters and disinfection by products (DBPs) were monitored and correlations between them were statistically investigated in a swimming pool in the province of Bitlis in Turkey. Risk assessment was then performed for trihalomethanes (THMs) and haloacetic acids (HAAs) in the context of public health. According to results, the carbonaceous organics (maximum total organic carbon (TOC): 3.89 mg/L) and nitrogenous (maximum total nitrogen (TN): 6.84 mg/L) substances came from swimmers as the precursor compounds for the formation of DBPs. Pool water free chlorine concentration varied depending on the manual dosage (between 0 to 2.2 mg/L) and sometimes exceeded the Turkish limits (1-1.5 mg/L). This situation increased DBPs formation. Bromide concentration detected in pool water can reach up to 15-fold the value in groundwater. This provides the basis for formation of brominated DBPs which are more carcinogenic than chlorinated species. The THM₄ (mean: 85.4 µg/L) and bromoform (mean: 70.2 µg/L) concentrations were higher than those obtained in most countries. Low nitrogenous compounds limited the haloacetonitrile (HAN) production (mean: 3.52 µg/L). Significant differences were detected between HAA₅ and HAA₉ concentrations (mean: 181 and 219 µg/L respectively) and this difference came from high amounts of brominated HAA species. Other DBPs that cannot be detected on species basis varied and constituted mean 53.5% of adsorbable organic halogens (AOX). This situation creates uncertainty in terms of health hazards. According to Pearson correlations, there were significant correlations between AOX formation and TOC, TN, conductivity, total chlorine, nitrate and temperature. This indicates that DBPs formation was mainly influenced by the precursors in the water and the physical conditions in the pool. Therefore these parameters are the fingerprint of DBP formation in the studied pool water and negative or positive changes in these parameters directly affect DBP generation. It is very important to keep them under constant control in pool water. According to the risk assessment results, HAA concentration in the pool was found to have the potential to pose a risk to public health. The study provides fingerprinting information for DBP formation under uncontrolled pool conditions.

在这项研究中，对水质参数和副产品消毒（DBPs）进行了监测，并在土耳其Bitlis省的一个游泳池中对它们之间的相关性进行了统计调查。然后在公共卫生范围内对三卤甲烷（THM）和卤乙酸（HAA）进行了风险评估。根据结果​​，游泳者的碳质有机物（最大总有机碳（TOC）：3.89 mg / L）和含氮（最大总氮（TN）：6.84 mg / L）物质是形成DBP的前体化合物。泳池水中的游离氯浓度根据手动剂量（0至2.2 mg / L）变化，有时超过土耳其的限值（1-1.5 mg / L）。这种情况增加了DBP的形成。在游泳池水中检测到的溴化物浓度可以达到地下水中浓度的15倍。这提供了形成溴化DBP的基础，该溴化DBP的致癌性比氯化物高。THM₄（平均：85.4 µg / L）和溴仿（平均：70.2 µg / L）的浓度高于大多数国家/地区。低氮化合物限制了卤代乙腈（HAN）的产量（平均值：3.52 µg / L）。在HAA ₅和HAA ₉之间检测到显着差异浓度（分别为181和219 µg / L），这种差异来自大量溴化HAA物种。其他基于物种无法检测到的DBP发生变化，平均构成可吸附有机卤素（AOX）的53.5％。这种情况在健康危害方面造成了不确定性。根据Pearson相关性，AOX的形成与TOC，TN，电导率，总氯，硝酸盐和温度之间存在显着相关。这表明DBPs的形成主要受水中前驱物和池中物理条件的影响。因此，这些参数是所研究池水中DBP形成的指纹，这些参数的负或正变化直接影响DBP的生成。使它们在游泳池水中受到持续控制非常重要。根据风险评估结果，发现池中的HAA浓度可能对公共健康构成风险。该研究提供了在不受控制的池条件下形成DBP的指纹信息。
