Despite the various methods used to disinfect swimming pool water, contamination by human health pathogens remains a serious problem. This study aims to compare the physicochemical parameters (residual chlorine level, temperature, and pH) during swimming with the significant contamination of swimming pool water in Blida city, Algeria, by five pathogenic bacteria harmful to human health: , , , and species. The comparison of pathogenic bacteria averages (colony-forming units (CFU)/100 mL) in the analyzed pool waters with residual chlorine levels (0- < 1 mg/mL) showed that , , and had significant differences ( ≤ 0.05). Similarly, and showed significant differences with pH levels (6.9-7.9), and only showed significant differences with temperature (24-29 °C). This study precisely highlights the relationship between residual chlorine, temperature, pH variations, and contamination by the five pathogenic bacteria despite proper water treatment before swimming.
尽管用于游泳池水消毒的方法多种多样，但人类健康病原体的污染仍然是一个严重问题。本研究旨在比较阿尔及利亚布利达市游泳期间的理化参数（余氯水平、温度和pH值）与对人类健康有害的五种致病细菌对游泳池水的严重污染情况： 、 、 、 和 菌属。分析的泳池水中致病细菌平均值（菌落形成单位（CFU）/100 mL）与余氯水平（0 - <1 mg/mL）的比较表明， 、 和 存在显著差异（ ≤ 0.05）。同样， 和 与pH值水平（6.⁹ - 7.⁹）存在显著差异，只有 与温度（24 - 29°C）存在显著差异。本研究精确地突出了尽管游泳前进行了适当的水处理，但余氯、温度、pH值变化与这五种致病细菌污染之间的关系。
