Swimming pools rank high among dangerous places for human recreation, which play an important role due to the high number of references and require continuous monitoring of pollutants and factors affecting it. Therefore, this study was conducted with the aim of systematically investigating the relationship between chlorine and heterotrophs in published studies in Iran. PubMed, Science Direct, and Google Scholar databases were searched from April 2000 to September 2022. Then identified studies were evaluated, then the studies lacking the necessary quality were excluded. From 686 articles, 33 reputable studied investigated the concentration of free chlorine in Iranian pool water. However, 14 studies measured the free chlorine and heterotrophs in swimming pools of 12 different Iranian cities. According to the results of the present study, the appropriate residual chlorine has reduced the microbial contamination of the pools, also, using the clarification in conjunction with the remaining free chlorine concentration, can help ensure the bacteriological quality of the water in the swimming pool. So maintaining the residual chlorine levels and daily cleaning of the pool can be effective in controlling heterotrophs in swimming pools and water recreational environments.
游泳池在危险的人类娱乐场所中排名靠前，由于其被提及的次数众多，因而起着重要作用，并且需要持续监测污染物及影响污染物的因素。因此，本研究旨在系统调查伊朗已发表研究中氯与异养菌之间的关系。在2000年4月至2022年9月期间对PubMed、Science Direct和谷歌学术数据库进行了检索。然后对识别出的研究进行评估，接着排除缺乏必要质量的研究。从686篇文章中，33项有信誉的研究调查了伊朗泳池水中游离氯的浓度。然而，有14项研究测量了伊朗12个不同城市游泳池中的游离氯和异养菌。根据本研究结果，适当的余氯减少了泳池的微生物污染，此外，将澄清处理与剩余游离氯浓度结合使用，有助于确保游泳池水的细菌学质量。因此，保持余氯水平和每日清洁泳池可有效控制游泳池和水上娱乐环境中的异养菌。
