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

> Hi Everyone,
> SOCAAR is pleased to announce an additional Seminar for October:
> Monday, October 31, 2016
> 2 ¨C 3 PM
> 200 College Street, WB 215
> PM2.5 components over China and their changes
> Dr. Fumo Yang
> Research Scientist & Director of Center for Atmospheric Environment
> Chongqing Institute of Green and Intelligent Technology
> Chinese Academy of Sciences
> 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.
