Abstract

Based on SO₂, NO_y, O₃, CO and PM_2.5 monitoring data of Beijing in 2012, the variation characteristics of PM_2.5 and reactive gas and the correlation with the meteorological conditions were discussed. The average mass concentration of PM_2.5 was 52.0μg/m³ in Beijing, 2012. The results showed that PM_2.5 had a large range over year with a slow accumulation and fast clearance variation especially in autumn and winter. NO_y, NO, CO and SO₂ showed the same trend with PM_2.5 changing, but O₃ changed in the opposite trend. The highest frequency of PM_2.5 appeared between 0~25μg/m³ for 27%. NO_y, NO, CO, SO₂ and PM_2.5 showed a rapid decrease at wind speed < 3m/s, among them, the reduction rate of PM_2.5 was ~ 25 %/(m/s). When the wind speed was > 3m/s, the pollutants reduced to a lower concentration and tended to be gentle. It was not showed significant influence of PM_2.5 mass concentration with the increasing of relative humidity on cleaning day, but showed rapidly increase of PM_2.5 on pollution days.

Key words： PM_2.5 reactive gas humidity meteorological elements
