Chemical composition of ambient PM2 Chemical composition of ambient PM2.5 over China and relationship to precursor emissions during 2005–2012 Guannan Geng, Qiang Zhang, Dan Tong, Meng Li, Yixuan Zheng, Siwen Wang, and Kebin He May 3, 2017

Severe PM2.5 pollution over China Primary pollutants in 2013 Mortality PM2.5 concentrations in 2013 above 100μg/m3 China (Apte et al., ES&T, 2016)

Datasets used in this study Ground measurements National monitoring network is unavailable between 2005 and 2012 Observations collected from literatures Satellite-based PM2.5 composition (2005-2012) Satellite AOD data from MODIS and MISR instrument GEOS-Chem model Bottom-up emissions MEIC inventory 𝑨𝑶𝑫 𝒔𝒂𝒕𝒆𝒍𝒍𝒊𝒕𝒆 × 𝑷𝑴 𝟐.𝟓_𝒎𝒐𝒅𝒆𝒍𝒆𝒅 ( 𝑪𝒐𝒎𝒑𝒐𝒏𝒆𝒕 𝒎𝒐𝒅𝒆𝒍𝒆𝒅 ) 𝑨𝑶𝑫 𝒎𝒐𝒅𝒆𝒍𝒆𝒅 𝑷𝑴 𝟐.𝟓_𝒔𝒂𝒕𝒆𝒍𝒍𝒊𝒕𝒆 𝑪𝒐𝒎𝒑𝒐𝒏𝒆𝒕 𝒔𝒂𝒕𝒆𝒍𝒍𝒊𝒕𝒆 (Geng et al., RSE, 2015) (Philip et al., ES&T, 2014)

Spatial distribution of PM2.5 composition

PM2.5 speciation for 20 major cities across China

Temporal variations in PM2.5 National population-weighted mean PM2.5 concentration increased from 2005 to 2007 and subsequently decreased from 2007 to 2012

Temporal variations in PM2.5 composition Sulfate Nitrate Ammonium OM BC Dust Sea salt -2.36%/yr +3.39%/yr

Temporal variations in SNA Sulfate concentration increased by 10.7% from 2005–2006 and then decreased by 4.3% per year from 2006–2012. The decrease of sulfate concentration is partly offset by the increase of nitrate concentration: population-weighted mean nitrate concentration increased by 3.4% per year during 2005–2012.

Relationship between PM2.5 composition and precursor emissions The changes in sulfate and nitrate concentrations were in line with the changes in SO2 and NOx emissions during the same period.

Region-specific emission change rates

Summary Variations in PM2.5 concentrations are mainly driven by the changes in sulfate and nitrate concentrations. The decrease of sulfate concentration is partly offset by the increase of nitrate concentration. Synchronized abatement of emissions for multi-pollutants are necessary for reducing ambient PM2.5 concentrations over China
