Urban particle pollution is affected by not only the emissions of pollutants and secondary
aerosol formation through atmospheric chemistry on a local scale, but also the regional …

Haze pollution is affected by local air pollutants, regional transport of background particles
and precursors, atmospheric chemistry related to secondary aerosol formation, and …

The characteristics of aerosol particles have been poorly evaluated even though haze
episodes frequently occur in winter in Northeast China. OC/EC analysis, ion …

Extremely severe haze weather events occurred in many cities in China, especially in the
east part of the country, in January 2013. Comprehensive measurements including hourly …

Heterogeneous reactions involving aerosol water, ie, haze chemistry, are responsible for
high aerosol concentrations observed during severe haze events in Chinese megacities …

Regional transport and heterogeneous reactions have been shown to play crucial roles in
haze formation over a megacity cluster centered on Beijing. In this study, the updated …

Continuous field observations of haze pollution were conducted in winter and summer
during 2015 in Zibo, a highly industrialized city in the North China Plain that is adjacent to …

Rapid industrialization and urbanization have caused frequent occurrence of haze in China
during wintertime in recent years. The sulfate aerosol is one of the most important …

Although there are many studies of particulate matter (PM) pollution in Beijing, the sources
and processes of secondary PM species during haze periods remain unclear. Limited …

In recent years in a few Chinese megacities, fog events lasting one to a few days have been
frequently associated with high levels of aerosol loading characterized by high sulfate (as …
