PM2. 5 chemical components play significant roles in the climate, air quality, and public
health, and the roles vary due to their different physicochemical properties. Obtaining …

Over the past decade, fine particulate matter (PM) pollution in China has been abated
significantly, benefiting from strict emission control measures, but particulate nitrate …

Until now, there has been a lack of knowledge regarding the vertical profiles of nitrate
formation in the urban boundary layer (BL) based on triple oxygen isotopes. Here, we …

Haze pollution occurs frequently over northern China Plain (NCP) during winter, resulting in
great threats to human health. So far, limited studies have linked between emission sources …

Abstract Fine particulate matter (PM 2.5) remains a major air pollutant of significant public
health concern in urban areas. Long-term monitoring data of PM 2.5 chemical composition …

Air quality in ammonia-rich regions such as Zhengzhou is improving year by year, however,
fine particulate matter (PM 2.5) pollution is serious in winter. Aerosol acidity (pH) affects …

With the coming of the “14th Five-Year Plan,” the coordinated control of particulate matter
with an aerodynamic diameter no greater than 2.5 μm (PM 2.5) and O 3 has become a major …

Abstract Nitrate (NO3−) is a major contributing species to haze formation in Northern China.
So far, formation processes and source apportionments of nitrate aerosols during haze …

High uncertainty in simulating the climate effect of black carbon (BC)-containing particles
can be raised by an important parameter: light absorption enhancement (E abs), which was …

Sulfate (SO42–) is a major species in atmospheric fine particles (PM2. 5), inducing haze
formation and influencing Earth's climate. In this study, the δ34S values in PM2. 5 sulfate …
