Spatiotemporal Variations and Evaluations of Ambient PM₁₀ Concentrations in Nanchong City, China

Abstract:

In order to further improve urban air quality, this study applied hourly PM₁₀ mass concentrations in 5 monitoring stations during 2008-2012 to discuss spatiotemporal variations and evaluate air quality in Nanchong city, southwest China. The results showed that the annual mean PM₁₀ concentrations during 5 years was 61.4μg/m³, and the concentrations order of 5 stations was JC (65.4μg/m³)>SW(64.6μg/m³)>JL(60.9μg/m³)>LY(60.4μg/m³)>GP(55.9μg/m³).The monthly mean concentrations in spring and winter were higher than in summer and fall. There was no obvious "weekend effect" in Nanchong and it was illustrated that the contributions to PM₁₀ of vehicle exhaust could be smaller. The hourly concentrations were 54.8~68.1μg/m³ from 0:00 to 23:00 and the maximum appeared at 12:00 and 21:00 for each station. The rate of reaching standard was 97.5~99.2% from 2008 to 2012 and the order was GP(99.2%)>LY(98.8%)>JL=SW(98.3%)>JC(97. 9%). The causes of these PM₁₀ variations need to be studied deeply.
