There has been a rapid increase in the number of public as well as private swimming pools in recent years. This is because the general public is now much more health and fitness-oriented, and swimming is thought by many to be the perfect form of exercise. Assessment of the environmental and health aspects of some of Alexandria swimming pools was carried out through the present study. All the recorded temperatures during the present study agreed with the Infectious Diseases Regulations. As regards turbidity, although the annual mean values of most pools had shown compliance with the allowable limit of the decree, there were many violations of the limit values in some individual results recorded during the different months. Most of the residual chlorine results recorded at the different pools during the different months showed that the operators were adding the Cl2 in a haphazard way. The low pH values could be attributed to the addition of slug doses of Cl2 which hydrolyze, producing high concentrations of hydrochloric and hydrochlorous acids. The high incidence of recorded itching and redness of the eyes followed by ear infections was attributed to the exposure to excess chlorine, and to the presence of pathogenic microorganisms. As regards the awareness and practice to pool hygienic instructions, the low percentage of swimmers using head caps during swimming (30.1%) was mainly comprised of females. It could be concluded that the majority of the users followed some of the hygienic instructions, like showering, washing the feet before entering the pool, and wearing bathing suites instead of private clothes. The frequencies of health problems observed among users were related to many factors, like age, marital status, occupation, frequency, and duration of use of the swimming pool.
近年来，公共和私人游泳池的数量都在迅速增加。这是因为普通大众现在更加注重健康和健身，而且许多人认为游泳是完美的锻炼方式。本研究对亚历山大港一些游泳池的环境和健康方面进行了评估。本研究期间记录的所有温度均符合《传染病条例》。关于浊度，虽然大多数游泳池的年平均值显示符合法令的允许限值，但在不同月份记录的一些个别结果中存在许多违反限值的情况。不同月份在不同游泳池记录的大多数余氯结果表明，操作人员添加氯气的方式随意。pH值低可能是由于添加了大量会水解的氯气，产生了高浓度的盐酸和次氯酸。记录的眼睛瘙痒和发红以及耳部感染的高发生率归因于接触过量氯气以及致病微生物的存在。关于对泳池卫生说明的认识和实践，游泳时使用泳帽的游泳者比例较低（30.1%），其中主要是女性。可以得出结论，大多数使用者遵循了一些卫生说明，如淋浴、进入泳池前洗脚以及穿着泳衣而不是便服。在使用者中观察到的健康问题频率与许多因素有关，如年龄、婚姻状况、职业、使用游泳池的频率和时长。
