Abstract Purpose of Review Fine particle (PM 2.5) levels have been decreasing in the USA
over the past decades. Our goal was to assess the current literature to characterize the …

Background: Evidence indicates that air pollution contributes to cardiopulmonary mortality.
There is ongoing debate regarding the size and shape of the pollution–mortality exposure …

Epidemiologic evidence indicates that exposure to fine particulate matter air pollution (PM
2.5) contributes to global burden of disease, primarily because of increased risk of …

Abstract Background In 1997 the US Environmental Protection Agency set the first annual
National Ambient Air Quality Standard (NAAQS) for fine particulate matter (PM 2.5). Although …

Many epidemiologic studies provide evidence of an association between daily counts of
mortality and ambient particulate matter< 10 μm in diameter (PM10). Relatively few studies …

Exposure to fine particulate matter (PM) results in adverse health outcomes. Although this is
a global concern, residents of China may be particularly vulnerable due to frequent severe …

Background Long-term exposure to ambient fine particulate matter (≤ 2.5 μg/m 3 in
aerodynamic diameter; PM 2.5) is significantly associated with increased risk of premature …

Background Although many studies have examined the effects of air pollution on mortality,
data limitations have resulted in fewer studies of both particulate matter with an aerodynamic …

Airborne particles have been linked to increased mortality and morbidity. As most research
has focused on fine particles (PM 2.5), the health implications of coarse particles (PM 10 …

Background: In 2012, the EPA enacted more stringent National Ambient Air Quality
Standards (NAAQS) for fine particulate matter (PM 2.5). Few studies have characterized the …
