Strategic Study of CAE 2014, Volume 16, Issue 10,   Pages 47-51

Abstract:

In recent years, frequent haze weather makes PM2.5 becoming the publicThe control of PM2.5 has been added in the 2012 release "ambient air quality standard".Under the situation that our current flue gas pollutant control technology is difficult to remove PM2.5the Flue Gas Pollutants Deep-removal Technology (DRT) for Coal-fired Power Plant for deep-removing PM2.5the necessity and existing problems of developing DRT suitable for China, this study focused on the PM2.5

Frontiers of Environmental Science & Engineering 2020, Volume 14, Issue 2, doi: 10.1007/s11783-019-1202-8

Abstract: There were one high value center for PM2.5 pollution and two low value centers.In 2004, 2009 and after 2013, PM2.5 concentration was relatively low.making it unfavorable for the prediction and prevention of PM2.5 pollutions.The tempo-spatial characteristics of PM2.5 and the influence of meteorological elements on PM2.5 is discussedAlthough, in 2004, 2009 and dates after 2013, PM2.5 concentrations were relatively low.

Estimating the effects of meteorology on PM

Liu YANG, Ye WU, Jerry M. DAVIS, Jiming HAO

Frontiers of Environmental Science & Engineering 2011, Volume 5, Issue 3,   Pages 331-341 doi: 10.1007/s11783-011-0307-5

Abstract: difficult to distinguish the effectiveness of those control measures since meteorology also affects ambient PMconducted to evaluate the effects of meteorology and emission control measures on the reduction of PMThe response variable was PM and the meteorology covariates used in the model were hourly temperatureWind direction was not a significant predictor of PM levels in either the control or the no controlcoefficients from the two time periods, meteorology was found to contribute to at least a 16% reduction in PM
