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 Quoting Pradheepa Baskaran <[log in to unmask]>: > 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. > > > > 1.
