中文摘要:
      利用2018—2021年安徽省空气质量监测数据分析了PM2.5和O3时空分布特征及其引发的健康风险。结果表明:从时间分布来看,2018—2021年安徽省PM2.5年均值下降25.5%,而O3-8 h年均值则保持持平;PM2.5和O3-8 h月均值具有明显的季节变化特征,PM2.5月均质量浓度和超标天数均在冬季达到最大值,O3-8 h月均值和超标天数则在夏季达到最大值。从空间分布来看,PM2.5、O3-8 h年均值和超标天数均为皖北最高,其次为皖中,最后为皖南。夏季O3是主要的健康风险因子,冬季PM2.5是主要的健康风险因子。当PM2.5超标时,除2021年皖北地区外(PM10是主要的健康风险因子),PM2.5均是主要的健康风险因子;当O3-8 h超标时,O3是主要的健康风险因子。
英文摘要:
      According to the air quality monitoring data in Anhui Province from 2018 to 2021,this paper analyzed the temporal and spatial characteristics of PM2.5 and O3 and their health risks. The study suggested that from the perspective of time distribution,the annual average values of PM2.5 in Anhui Province decreased by 25. 5% from 2018 to 2021,while the annual average values of O3-8 h remained unchanged;the monthly average mass concentrations of PM2.5 and O3 -8 h had obvious seasonal variation characteristics; the monthly average mass concentration and exceeding days of PM2.5 reached the maximum value in winter,while the monthly average mass concentration and exceeding days of O3-8 h reached the maximum value in summer. From the perspective of spatial distribution,the annual average concentrations and exceeding days of PM2.5 and O3 -8 h were the highest in northern Anhui,followed by central Anhui,and finally southern Anhui. O3 was the main health risk factor in summer and PM2.5 was the main health risk factor in winter. When PM 2. 5 exceeded the standard,except for northern Anhui in 2021 (PM10 was the main health risk factor),PM2.5 was the main health risk factor; When O3-8 h exceeded the standard, O3 was the main health risk factor.
