室内游泳馆中三卤甲烷的研究进展及其对儿童健康的影响

Advances of trihalomethanes in indoor swimming pools and their health effects on children

室内游泳场馆是一个大型的公共场所,环境十分复杂。目前大多数游泳池水采用的消毒方式为氯化消毒,而这种方法的弊端是容易产生大量氯化消毒副产物,如THMs、HAAs,其中THMs占大多数。其可通过附着人体皮肤、呼吸道等进入人体,从而对眼睛、呼吸系统及多个器官的健康产生不利影响。而儿童作为特殊人群,较其他人群更易受到游泳场馆中各类化学物质的影响。鉴于此,本研究拟对室内游泳馆中氯化消毒副产物的产生及种类、暴露途径、国内外检测水平状况及限值标准、对儿童的不良健康效应进行总结分析,以期为室内游泳场馆环境卫生问题的相关研究提供参考。

The indoor swimming pool is a large public place,and its environment is very complex.At present,most of the disinfection methods used in swimming pool water are chlorination disinfection.This method easily reacts with other chemicals in the water to generate a large amount of chlorination disinfection by-products.The main types are THMs and HAAs.It can enter the human body through the skin,respiratory tract and digestive tract,thereby adversely affecting the health of human eyes,respiratory system,and multiple organs.As a special population,children are more susceptible to the risks caused by various chemicals in swimming venues than other populations.In view of this,this study intends to summarize and analyze the generation and exposure pathways of chlorinated disinfection by-products in indoor swimming pools,the detection level at home and abroad and the limit standards,and the adverse health effects of children,to provide reference for a view to studying the environmental health issues of indoor swimming pools.
