Particulate matter from biomass burning emissions affects air quality, ecosystems and
climate; however, quantifying these effects requires that the connection between primary …

Emissions from biomass burning (BB) vastly contribute to the atmospheric trace gases and
particles, which affect air quality and human health. After emission, the chemical evolution …

Residential biomass burning for heating purposes is an important source of air pollutants
during winter. Here we test the hypothesis that significant secondary organic aerosol …

We report the physical and chemical effects of photochemically aging dilute biomass-
burning smoke. A" potential aerosol mass"(PAM) flow reactor was used with analysis by a …

Oxidative potential (OP), which is the ability of certain components in atmospheric particles
to generate reactive oxidative species (ROS) and deplete antioxidants in vivo, is a prevailing …

Biomass burning is an important source of aerosol and trace gases to the atmosphere, but
how these emissions change chemically during their lifetimes is not fully understood. As part …

Multiphase reactions with nitrate radicals are among the most important chemical aging
processes of organic aerosol particles in the atmosphere especially at nighttime. Reactive …

Smog chamber experiments were conducted to investigate the chemical and physical
transformations of organic aerosol (OA) during photo-oxidation of open biomass burning …

N2O5 and ClNO2, important oxidant reservoirs, were recently demonstrated to be produced
in simulated nocturnal aging of biomass-burning smoke. However, the heterogeneous …

Oxidized organic aerosol (OOA) is a major component of ambient particulate matter,
substantially impacting climate, human health, and ecosystems. OOA is readily produced in …
