TL;DR: The results of the present study provide a scientific basis for the development of PM2.5 control strategies on a regional scale and suggest local emission may be non-negligible at YRDNNR in summer.

TL;DR: Correlation coefficient analysis and principal component analysis revealed that Cu, Fe, Mn, Pb, and Zn were originated from vehicular traffic and industrial emissions at both sites; As, Cr, and part of Pb from coal-fired power plant; Ba and Ti from natural soil.

TL;DR: The size-fractionated characteristics of particulate polycyclic aromatic hydrocarbons were studied from January 2011 to October 2011 using a Micro-orifice Uniform Deposit Impactor at the Yellow River Delta National Nature Reserve, a background site located in the North China Plain and demonstrated that atmospheric PAHs were produced primarily by local anthropogenic sources.

TL;DR: Air pollutants on the regional scale likely contribute 40%–90% of the fine particles in the Hangzhou urban area during the long-range transport events, which highlights the future control and model forecasting of air pollutants in Hangzhou and similar megacities in eastern China.

TL;DR: In order to determine physicochemical properties of aerosols before leaving the Asian continent, Wang et al. as mentioned in this paper carried out a field campaign from 14 April to 2 May 2011 at a background site in the path of Asian dust and haze outflows.
