摘要

游泳池水消毒对于确保游泳者的娱乐活动安全至关重要。然而,游泳池会不断从进水和人为污染中摄入有机物,导致消毒副产物(DBPs)水平升高。流行病学研究表明,经常接触游泳池中的 DBPs 会增加不良健康影响的风险。Zhang 等人(2023b)调查了华东某城市 8 个游泳池和相应进水中三卤甲烷 (THMs)、卤乙酸 (HAAs)、卤乙腈 (HANs) 和卤乙醛 (HALs) 的含量。游泳池中的三卤甲烷、二卤甲烷、卤乙烷和卤乙醛的浓度比输入水中检测到的浓度高出 1-2 个数量级。采用美国环境保护局(USEPA)的标准模型和游泳者暴露评估模型(SWIMODEL),评估了游泳者通过口腔、皮肤、吸入、口腔和听觉等暴露途径一生中的癌症和非癌症健康总风险。结果表明,皮肤和吸入途径对相关癌症和非癌症风险的影响最大。本文概述了游泳池中的 DBPs、游泳的好处、改进 DBPs 监测的必要性以及游泳者保持游泳池清洁的卫生习惯的重要性,并从多个角度阐述了这些问题。为了促进公众健康,游泳的益处大于暴露于 DBP 带来的风险。

Swimming benefits outweigh risks of exposure to disinfection byproducts in pools

Disinfection of swimming pool water is critical to ensure the safety of the recreational activity for swimmers. However, swimming pools have a constant loading of organic matter from input water and anthropogenic contamination, leading to elevated levels of disinfection byproducts (DBPs). Epidemiological studies have associated increased risks of adverse health effects with frequent exposure to DBPs in swimming pools. Zhang et al. (2023b) investigated the occurrence of trihalomethanes (THMs), haloacetic acids (HAAs), haloacetonitriles (HANs), and haloacetaldehydes (HALs) in eight swimming pools and the corresponding input water in a city in Eastern China. The concentrations of THMs, HAAs, HANs, and HALs in swimming pools were 1–2 orders of magnitude higher than those detected in the input water. The total lifetime cancer and non-cancer health risks of swimmers through oral, dermal, inhalation, buccal, and aural exposure pathways were assessed using the United States Environmental Protection Agency's (USEPA) standard model and Swimmer Exposure Assessment Model (SWIMODEL). The results showed that dermal and inhalation pathways were the most significant for the associated cancer and non-cancer risks. This article provides an overview and perspectives of DBPs in swimming pools, the benefits of swimming, the need to improve the monitoring of DBPs, and the importance of swimmers’ hygiene practices to keep swimming pools clean. The benefits of swimming outweigh the risks from DBP exposure for the promotion of public health.

期刊介绍: The Journal of Environmental Sciences is an international journal started in 1989. The journal is devoted to publish original, peer-reviewed research papers on main aspects of environmental sciences, such as environmental chemistry, environmental biology, ecology, geosciences and environmental physics. Appropriate subjects include basic and applied research on atmospheric, terrestrial and aquatic environments, pollution control and abatement technology, conservation of natural resources, environmental health and toxicology. Announcements of international environmental science meetings and other recent information are also included.
