Aerosol acidity plays an important role in atmospheric chemistry. China emits large amounts
of SO2, NOx, and NH3 into the atmosphere, but aerosol acidity is poorly characterized. In …

Spatiotemporal variations of six criteria air pollutants and influencing factors in the city
clusters of Sichuan Basin were studied based on real-time hourly concentrations of PM 2.5 …

Particulate nitrate (pNO3–) has often been found to be the major component of fine particles
in urban air-sheds in China, the United States, and Europe during winter haze episodes in …

To investigate the characteristics of PM 2.5 and its major chemical components, formation
mechanisms, and geographical origins in the two megacities, Chengdu (CD) and …

Secondary inorganic aerosols, including sulfate, nitrate, and ammonium contribute to a large
extent to the severe haze pollution events in China. Understanding their formation …

This study conducted a field campaign using a time-of-flight aerosol chemical speciation
monitor (ToF-ACSM) for PM 2.5 measurement at a rural site in Sichuan Basin (SCB) during …

Regional PM 2.5 and ozone pollution and inter-city transportation in the city clusters of the
Sichuan Basin (SB) were revealed using k-means clustering and the HYSPLIT backward …

Sulfate, nitrate and ammonium are the most abundant secondary inorganic aerosols (SIA) in
atmospheric fine particle matter (PM 2.5). Meteorological conditions, gas-particle …

Aerosol acidity plays a crucial role in atmospheric physicochemical processes, climate
change and human health, particularly in the formation of secondary organic aerosols …

Chengdu, a typical basin city in China, still suffers from severe haze pollution in recent
years. To gain a comprehensive understanding of the chemical causes and sources of fine …
