Abstract

Air pollution has become worldwide environmental issue in present day. In this study, the concentrations of PM10 was analyzed with hourly datasets, and the data of meteorological conditions were measured per 3 hours from 1st Sep 2014 to 30th Sep 2016 at Fuzhou city in the southeastern China. The mean value of mass concentration of PM10 is 54.65±24.07μg m−3 in the study period. The correlation coefficient between mass concentrations of PM10 and meteorological factors were analyzed, it shows that there existed a negative correlation between PM10 and T (−0.03), RU (-0.27), WS (−0.10), HCC (−0.04), VIS (−0.31), DPT (-0.15) and RF (-0.14). Subsequently, the impacts of typhoons on the mass concentrations of PM10 during September 10th 2016 to September 16th 2016 were analyzed during which the mass concentration of PM10 decreased at a large extent and the particulates have more prominent changes during the typhoon period compared with coarse particulates.
