Chemical Composition and Source Apportionment of PM2.5 in a Border City in Southwest China

Jianwu Shi et al.

Summary: This study investigated the chemical characteristics and seasonal variations of PM2.5 in plateau cities on the southwest border of China. The findings revealed that during the wet season, most air masses originated from the Indian Ocean and Myanmar, while during the dry season, they mainly came from the China-Myanmar border area. The major sources of PM2.5 were identified as secondary inorganic aerosols, dust, industrial emissions, biomass burning, motor vehicle emissions, and copper smelting emissions.

Chemical Composition Characteristics and Source Contributions of Precipitation in Typical Cities on the North Slope of Tianshan Mountain in Xinjiang during 2010-2019

Yuting Zhong et al.

Summary: This study investigated the characteristics and sources of precipitation pollution in typical cities on the North Slope of Tianshan Mountain, Xinjiang for a period of ten years (2010-2019). The results showed that Urumqi had the highest pollution level, while Yining had the lowest. Human activities were identified as the main source of ions in precipitation, with natural sources also playing a significant role.

Source apportionment in PM2.5 in central Japan using positive matrix factorization focusing on small-scale local biomass burning

Fumikazu Ikemori et al.

Summary: This study discusses the impacts of small-scale biomass burning on air quality in urban and suburban areas of central Japan, showing that in fall BB is a significant source of PM2.5, organic carbon, and elemental carbon. High concentrations of levoglucosan were observed at both suburban and urban sites, with air masses transported from Northeast China influencing levoglucosan levels. Local or regional BB emissions were prevalent at most sites, with urban sites near farmland showing higher BB contributions to PM2.5 in fall and winter.

Jianwu Shi et al.

Summary: The study investigated the chemical characteristics and sources of PM2.5 in Wenshan, revealing that secondary inorganic aerosols are the major contributors to PM2.5, and elements from anthropogenic sources have a high proportion in PM2.5. The research provides effective support for local governments in formulating air pollution control policies.
