Abstract The biomass burning increases the concentration of PM10. In this paper, the authors first took biomass burning hot spots,10 meters wind field and AOD into consideration to analyze the meteorological mechanism of the case of the PM10 pollution during June 1—9, 2009 in Anhui and its neighboring provinces. Moreover, by tracking the air mass of the case of the PM10 pollution in Fuyang on June 5, 2009 by the simulation of the HYSPLIT model, the authors analyzed the backward trajectory of the case. Finally, the correlation coefficients between hot spots and AOD were calculated. The results clearly show that there was a significant consistence between the biomass burning hot spots,10 meters wind field and AOD, suggesting that it is feasible to monitor the biomass burning by using AOD data, and that the transported pollutants related to the case of the PM10 pollution in Fuyang on June 5, 2009 mainly came from western Fuyang, middle and southeast Henan Province and northern as well as eastern Hubei Province. Therefore, it is very necessary to strengthen regional united precautions and controls of biomass burning. In addition, there was a positive correlation between hot spots and AOD, implying that biomass burning increases significantly the value of regional AOD.
