This work presents a three-year continuous observation of ozone (O 3) and fine particle (PM
2.5), as well as their precursors in Qingdao, China, from September 2018 to August 2021 …

Fine particulate matter (PM) significantly affects visibility, a sensitive indicator of air pollution.
Despite a continuous decrease in the PM concentrations in South Korea, the public …

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

Atmospheric ammonia (NH 3) is an important particulate matter (PM) precursor. The primary
sources of ammonia in agriculture are livestock farming and synthetic fertilizers. Here, an …

Despite its profound influence on air quality, the aerosol acidity, quantifiable by aerosol pH
is poorly characterized in South Korea where high concentrations of fine particles have …

Nitrate pollution is a significant contributor to poor air quality and adverse health effects,
especially in NH 3-rich environments. This study investigated the reduction of particulate …

Atmospheric inorganic gases such as NO x, SO 2, and NH 3 have diverse effects on the
formation of secondary organic aerosol (SOA). A comprehensive investigation is necessary …

Remarkably, enhanced particulate nitrate (NO3−) concentrations occur in many
environments during particulate matter (PM) pollution; however, information on the formation …

The aging timescale of particles is a key parameter in determining their impacts on air
quality, human health, and climate. In this study, a one-year simulation of the age …

A semi-continuous monitoring system, a parallel plate wet denuder and particle into liquid
sampler coupled with ion chromatography (PPWD-PILS-IC), was used to measure the hourly …
