The severe winter haze episode that occurred in Shanghai from December 2013 to January
2014, characterized by elevated levels of particulate matter (PM), received considerable …

The abundance, behavior, and source of chemical species in size-fractionated atmospheric
particle were studied with a 13-stage low pressure impactor (ELPI) during high polluted …

Organic aerosol (OA) constituted a large fraction of aerosol particles during severe haze
episodes in winter in northern China, yet our understanding of its physical and chemical …

In this study, we present a regional insight into characteristics and formation process of the
widespread extreme haze pollution in northern China during January of 2013 using …

To study the size-fractionated characteristics of aerosol chemical compounds including
major water-soluble inorganic and organic ions, situ pH and water content as well as their …

Severe PM 2.5 pollution was observed frequently in Beijing. We conducted highly time-
resolved measurements of inorganic ions associated with PM 2.5 at an urban site in Beijing …

Airborne particles in urban Beijing during haze days and normal days were collected and
analyzed in the autumn and winter seasons to reveal the chemical characteristics variations …

China experienced severe haze pollution in January 2013. Here we have a detailed
characterization of the sources and evolution mechanisms of this haze pollution with a focus …

Size segragated samples were collected during high polluted winter haze days in 2006 in
Beijing, China. Twenty nine elements and 9 water soluble ions were determined. Heavy …

Aerosol size distribution and chemical composition are found to have significant effects on
its hygroscopicity, acidity/alkalinity and light extinction. Heavy haze pollution occurred …
