Chronic exposure to fine particulate matter (PM 2. 5) poses a major global health risk,
commonly assessed by assuming equivalent toxicity for different PM 2. 5 constituents. We …

Secondary air pollutants, originating from gaseous pollutants and primary particulate matter
emitted by natural sources and human activities, undergo complex atmospheric chemical …

Understanding the sources, mechanisms, and potential health impacts of volatile organic
compounds (VOC) and secondary organic aerosols (SOA) is crucial for safeguarding human …

Organic aerosol (OA) is the largest and most complicated component of aerosols that greatly
affect human health and global climate. However, widely used models cannot reproduce …

Consumer products are important sources of exposure to harmful chemicals. Product
composition is often a mystery to users, however, due to gaps in the laws governing …

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) …

Anthropogenic organic carbon emissions reporting has been largely limited to subsets of
chemically speciated volatile organic compounds. However, new aircraft-based …

The impact of aerosols on human health and climate is well-recognized, yet many studies
have only focused on total PM2. 5 or changes from anthropogenic activities. This study …

Secondary organic aerosol (SOA) formation from gasoline vehicles spanning a wide range
of emission types was investigated using an oxidation flow reactor (OFR) by conducting …

China's industrial restructuring and pollution controls have altered the contributions of
individual sources to varying air quality over the past decade. We used the GEOS-Chem …
