Particulate matter (PM), an important component of air pollution, induces significant adverse
health effects. Many of the observed health effects caused by inhaled PM are associated …

Background: Secondary organic aerosols (SOAs) formed from anthropogenic or biogenic
gaseous precursors in the atmosphere substantially contribute to the ambient fine particulate …

Air pollution represents a major health problem and an economic burden. In recent years,
advances in air pollution research has allowed particle fractionation and identification of …

Exposure to ambient fine particulate matter (PM2. 5) is associated with millions of premature
deaths annually. Oxidative stress through overproduction of reactive oxygen species (ROS) …

The health effects of exposure to secondary organic aerosols (SOAs) are still limited. Here,
we investigated and compared the toxicities of soot particles (SP) coated with β-pinene SOA …

Physicochemical analysis of individual atmospheric aerosols at the most abundant sizes in
the atmosphere (< 1 μm) is analytically challenging, as hundreds to thousands of species …

The COVID-19 outbreak provides a “controlled experiment” to investigate the response of
aerosol pollution to the reduction of anthropogenic activities. Here we explore the chemical …

Widespread smoke from wildfires and biomass burning contributes to air pollution and the
deterioration of air quality and human health. A common and major emission of biomass …

Hydroxyl radical (· OH)-initiated oxidation of isoprene, the most abundant nonmethane
hydrocarbon in the atmosphere, is responsible for substantial amounts of secondary organic …

Heterogeneous hydroxyl radical (• OH) oxidation is an important aging process for isoprene
epoxydiol-derived secondary organic aerosol (IEPOX-SOA) that alters its chemical …
