济源市不同区域环境空气质量状况分析

Analysis of ambient air quality of different regions in Jiyuan

基于山区农村、平原农村及城市三个区域2019年的监测数据,分析了济源市内不同区域的环境空气质量状况。结果表明:三个区域的可吸入颗粒物、细颗粒物、臭氧年均值均超出标准值,分别为91μg/m^(3)、55μg/m^(3)和193μg/m^(3)。二氧化硫、二氧化氮、一氧化碳年均值均达到标准值,分别为14μg/m^(3)、31μg/m^(3)和1.8 mg/m^(3)。环境空气质量综合指数从高到低排序依次为城市站、平原农村站、山区农村站。

Based on the monitoring data of mountainous rural area,plain rural area and urban area in 2019,the ambient air quality of different regions of Jiyuan city was analyzed.The results show that the average annual concentrations of inhalable particulate matter,fine particulate matter and ozone in the three areas are 91μg/m 3,55μg/m^(3) and 193μg/m 3,respectively,which exceed the standards.The average annual concentrations of SO_(2),NO_(2) and CO are 14μg/m 3,31μg/m^(3) and 1.8 mg/m 3,respectively,which meet the standards.The comprehensive index of ambient air quality ranked from high to low is urban station,plain rural station and mountainous rural station.
