近年来,室外大气污染,主要包括细颗粒物(PM2.5)污染物,受到公众的广泛关注。家用空气净化器的产量和销量呈历史性的快速增长,家长提出了在学校安装空气净化器的诉求。学校作为公共场所的室内环境,使用针对家庭环境而研制的空气净化器,在满足教室的通风换气、安全疏散、传染病防控等方面,有诸多不相宜甚至矛盾的地方。学校教室安装空气净化器的使用和维护,目前缺乏相关社会公共部门的有效监管,这为后续的使用带来诸多不确定性。学校室内环境中使用空气净化器的人群健康效应,还需要进一步开展基于环境医学的调研和科学评估。相关管理部门可以此作为出发点,制定中长期的学校室内空气质量改善措施,为保护儿童青少年的身心健康,建设安全、健康、舒适的校园室内环境作出积极贡献。
In recent years, outdoor air pollution, including fine particulate matter (PM2.5) pollutants, has attracted widespread public attention. Domestic air purifier production and sales showed a historic rapid growth, parents proposed the installation of air purifiers in schools appeal. The school, as an indoor environment in public places, uses air purifiers developed for the home environment. There are many areas that are not suitable or even contradictory in meeting classroom ventilation, safe evacuation and prevention and control of infectious diseases. The use and maintenance of air purifiers in school classrooms is currently lacking in effective supervision of the relevant public sector, which creates a lot of uncertainty for subsequent use. The crowd health effects of using air purifiers in school indoor environments also require further research and scientific assessments based on environmental medicine. Relevant management departments can use this as a starting point to formulate medium and long term measures to improve school indoor air quality and make positive contributions to protecting the physical and mental health of children and adolescents and building a safe, healthy and comfortable campus indoor environment.
