Disparities in outdoor air pollution exposure between individuals of differing socio-economic
status is a growing area of research, widely explored in the environmental health literature …

Atmospheric chemistry research has been growing rapidly in China in the last 25 years
since the concept of the “air pollution complex” was first proposed by Professor Xiaoyan …

Gaseous nitrous acid (HONO) is a critical source of hydroxyl radicals (OH) in the
troposphere. While both direct and secondary sources contribute to atmospheric HONO …

A vast area in China is currently going through severe haze episodes with drastically
elevated concentrations of PM 2.5 in winter. Nitrate and sulfate are the main constituents of …

High levels of HONO have frequently been observed in Chinese haze periods and
underestimated by current models due to some unknown sources and formation …

Soot, mainly composed of elemental carbon (EC) and organic carbon (OC), plays an
important role in the formation of atmospheric nitrous acid (HONO) through the …

The importance of dust heterogeneous oxidation in the removal of atmospheric SO 2 and
formation of sulfate aerosols is not adequately understood. In this study, the Fe-, Ti-, and Al …

Abstract Properties of PM 2.5 that can change aerosol chemistry and photolysis rates have
great impacts on O 3 sensitivity regime, further affecting the production rate of surface O 3 …

Nitrous acid (HONO) is a key reservoir of the hydroxyl radical (OH) and plays a central role
in the atmospheric chemistry. To understand the sources and impact of HONO in the …

Mineral dust serves as a significant source of sulfate aerosols by mediating heterogeneous
sulfur dioxide (SO2) oxidation in the atmosphere. Given that a considerable proportion of …
