Abstract

Using automatic monitoring data of PM2.5 / PM10 Urumqi city,and analyzed concentration distribution and temporal variation of PM2.5 and PM10.The results showed that the standard limits in accordance with the ambient air quality standard(second draft),Urumqi,PM2.5 pollution in winter was more serious than PM10.PM2.5 concentration was 0.164 mg/m3,over the 2 year standard limit of 3.7 times,exceeded the rate was 73.9%.PM2.5 concentration diurnal variation curve was day high and night low,single peak,the peak appeared in the 13:00 to 14:00 pm.PM10,PM2.5 shared a higher proportion,PM2.5/PM10 was 0.79,analysis and tests had shown a significant linear correlation of PM2.5 and PM10,correlation coefficient was 0.92.
