Growing evidence suggests that fine particulate matter (PM2. 5) likely increases the risks of
dementia, yet little is known about the relative contributions of different constituents. Here …

Particulate matter source apportionment (SA) is the basis and premise for preventing and
controlling haze pollution scientifically and effectively. Traditional offline SA methods lack …

We investigate the sources, chemical composition, and spectral properties of light-absorbing
organic aerosol extracts (ie, brown carbon, or BrC) in the Los Angeles (LA) Basin during the …

The carbonaceous particles represent a significant fraction in the particulate matter (PM) and
are considered an environmental hazard due to their effects on climate and health. The main …

Black carbon (BC) is of significant interest from a human exposure perspective but also due
to its impacts as a short-lived climate pollutant. In this study, sources of BC influencing air …

High PM 2.5 episodes frequently occur in Northeast Asia, and the source− receptor
relationship for PM 2.5 in megacities is a critical issue. As the largest industrial city in South …

Linear regression techniques are widely used in atmospheric science, but they are often
improperly applied due to lack of consideration or inappropriate handling of measurement …

Bei**g has suffered from heavy local emissions as well as regional transport of air
pollutants, resulting in severe atmospheric fine-particle (PM2. 5) pollution. This study …

Black carbon (BC) particles in the atmosphere can absorb more light when coated by non-
absorbing or weakly absorbing materials during atmospheric aging, due to the lensing …

Sand and dust have significant impacts on air quality, climate, and human health. To
investigate the influences of dust storms on chemical characterization and source …
