Implementation of regulatory standards has reduced exhaust emissions of particulate matter
from road traffic substantially in the developed world. However, nonexhaust particle …

Background Climate change is likely to increase the threat of wildfires, and little is known
about how wildfires affect health in exposed communities. A better understanding of the …

Soluble transition metals in particulate matter (PM) can generate reactive oxygen species in
vivo by redox cycling, leading to oxidative stress and adverse health effects. Most metals …

A number of models have been developed to estimate PM2. 5 exposure, including satellite-
based aerosol optical depth (AOD) models, land-use regression, or chemical transport …

Background The link between PM 2.5 exposure and adverse health outcomes is well
documented from studies across the world. However, the reported effect estimates vary …

Biomass burning (BB) including forest, bush, prescribed fires, agricultural fires, residential
wood combustion, and power generation has long been known to affect climate, air quality …

Background: Current air quality standards for particulate matter (PM) use the PM mass
concentration [PM with aerodynamic diameters≤ 10 μm (PM10) or≤ 2.5 μm (PM2. 5)] as a …

Exposure to atmospheric fine particulate matter (PM2. 5) is associated with cardiorespiratory
morbidity and mortality, but the mechanisms are not well understood. We assess the …

This article briefly reviews evidence of health effects associated with exposure to particulate
matter (PM) air pollution from five common outdoor emission sources: traffic, coal-fired …

The diversity of ambient particle size and chemical composition considerably complicates
pinpointing the specific causal associations between exposure to particles and adverse …
