Hi Dheepa,

Is this one just a teleconference? Or is it an in-person talk in  
Wallberg that you can also call into?

Best,

Michelle

> PM2.5 components over China and their changes

> Dr. Fumo Yang is a Research Scientist and Director of Research  
> Center for Atmospheric Environment, Chongqing Institute of Green and  
> Intelligent Technology, Chinese Academy of Sciences. He received his  
> Ph.D. from School of Environment, Tsinghua University (2002). His  
> research interests are in the area of atmospheric aerosols, with a  
> focus on PM2.5 characterization and source apportionment. He has  
> published more than 90 peer-viewed journal papers (including two  
> highly cited papers ¡°The characteristics of PM2.5 in Beijing,  
> China¡± and ¡°Characteristics of PM2.5 speciation in representative  
> mega cities and across China¡±) and a scholarly monograph  
> (¡°Atmospheric particulate matter and regional complex pollution¡±,  
> 2011). He received the second prize of State Natural Science Awards,  
> China (2009), and the 2013 national book award.

> Abstract: The magnitude and spatial pattern of PM2.5 mass and  
> chemical speciation varied noticeably over geographic regions in  
> China. While noticeable progress in clean air campaign has been  
> achieved in recent years, PM2.5 was still at high levels. North  
> region suffered the most severe PM2.5 pollution, followed by  
> Northwest and Central China. Sulfate, nitrate and ammonium together  
> (SNA, usually referred to secondary inorganic aerosol) constituted  
> one-third of PM2.5 mass on average, exhibiting a clear decreasing  
> gradient from North and East to the South and Southwest China,. It  
> was evident that nitrate and ammonium concentrations, and the mass  
> ratio of NO3¨C to SO42¨C increased constantly during recent years.  
> Organic material was a relatively constant and significant  
> contributor to PM2.5 mass across China, accounting for 15¨C51%. Due  
> to transported desert dust, local soil dust and construction  
> activities, high content of crustal material occurred mainly in  
> Northwest China. The fract
> ion of EC in PM2.5 mass ranged from 2% to 12% with an average value   
> of 6%. A clear decline trend for EC mass was found in several mega   
> cities, such as Beijing, Chongqing, and Shanghai.
