Swimming is one of the most popular aquatic activities. Just like natural water, public pool water may contain microbiological and chemical contaminants. The purpose of this study was to study the presence of chemical contaminants in swimming pools, in particular the presence of disinfection by-products (DBPs) such as trihalomethanes (THMs), haloacetic acids (HAAs) and inorganic chloramines (CAMi). Fifty-four outdoor and indoor swimming pools were investigated over a period of one year (monthly or bi-weekly sampling, according to the type of pool) for the occurrence of DBPs. The results showed that DBP levels in swimming pools were greater than DBP levels found in drinking water, especially for HAAs. Measured concentrations of THMs (97.9 vs 63.7 μg/L in average) and HAAs (807.6 vs 412.9 μg/L in average) were higher in outdoor pools, whereas measured concentrations of CAMi (0.1 vs 0.8 mg/L in average) were higher in indoor pools. Moreover, outdoor pools with heated water contained more DBPs than unheated pools. Finally, there was significant variability in tTHM, HAA9 and CAMi levels in pools supplied by the same municipal drinking water network, suggesting that individual pool characteristics (number of swimmers) and management strategies play a major role in DBP formation.
游泳是最受欢迎的水上活动之一。就像天然水一样，公共泳池水可能含有微生物和化学污染物。本研究的目的是研究游泳池中化学污染物的存在情况，特别是消毒副产物（DBPs）的存在情况，如三卤甲烷（THMs）、卤乙酸（HAAs）和无机氯胺（CAMi）。在一年的时间里（根据泳池类型进行每月或每两周一次的采样），对 54 个室外和室内游泳池进行了调查，以研究 DBPs 的存在情况。结果表明，游泳池中的 DBP 水平高于饮用水中的 DBP 水平，尤其是 HAAs。室外泳池中 THMs（平均 97.9 与 63.7μg/L）和 HAAs（平均 807.6 与 412.9μg/L）的测量浓度较高，而室内泳池中 CAMi（平均 0.1 与 0.8mg/L）的测量浓度较高。此外，加热水的室外泳池比未加热的泳池含有更多的 DBPs。最后，来自同一城市饮用水管网的泳池中 tTHM、HAA9 和 CAMi 的水平存在显著差异，这表明个别泳池的特性（游泳人数）和管理策略在 DBP 形成中起着重要作用。
