Study progress on monitoring technologies and health effects of air quality in urban rail transit
With the acceleration of urbanization,urban rail transit systems have become one of the most important modes of transportation in modern cities.Urban rail transit systems operate in enclosed or semi-enclosed environments,characterized by poor air circulation and high passenger flow.During the period of high incidence of respiratory infectious diseases in autumn and winter,air quality and pathogenic microorganism monitoring in public places have attracted much at-tention.This article provided a detailed introduction to air pollutants and their sources related to urban rail transit,including chemical pollutants,such as particulate matter and gaseous pollu-tants,and microbial aerosols.Based on identified air pollutants related to urban rail transit,this paper reviewed the research progress on air quality monitoring technologies for chemical pollution factors and microbial aerosols.Finally,a summary of the health effects of chemical pollutants and microbial aerosols was provided,along with suggestions for monitoring and improving air quality tailored to the characteristics of urban rail transit systems.Through a review of previous studies,carrying out research on air quality monitoring technologies and associated health effects related to urban rail transit is of great significance and values for air quality management,urban development,and public health.
