摘      要：Air pollution is one of the biggest environmental threats to human health.In 2005,the World Health Organization(WHO)released its first global air quality guidelines(AQGs)for particulate matter(PM),ozone(O3),nitrogen dioxide(NO2),and sulfur dioxide.[1]On September 22,2021,the WHO updated its AQGs,providing clear evidence of the adverse health effects of air pollution,at even lower concentrations than previously understood.[2]For instance,the WHO AQGs 2021 recommend annual mean concentrations of PM2.5 not exceeding 5μg/m3 and NO2 not exceeding 10μg/m3 and the peak season mean 8-h O3 concentration not exceeding 60μg/m.[2,3]As a comparison,the corresponding WHO AQGs 2005 values were 10μg/m3 for PM2.5 and 40μg/m3 for NO2,with no recommendation for long-term O3 concentrations.
