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 …

Objective Several epidemiologic studies provide evidence of an association between daily
mortality and particulate matter< 2.5 μm in diameter (PM2. 5). Little is known, however, about …

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 …

Background Recent toxicological and epidemiological studies have shown associations
between particulate matter (PM) and adverse health effects, but which PM components are …

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 …

Background Prospective cohort studies constitute the major source of evidence about the
mortality effects of chronic exposure to particulate air pollution. Additional studies are …

Several epidemiologic studies have reported associations between respiratory disease and
particulate matter less than 2.5 μm in diameter (PM2. 5) or fine particles. However, since …

Many epidemiological studies provide evidence of an association between airborne
particles, measured as PM10 (particulate matter less than 10 μm in diameter), and daily …

Background: Ambient fine particulate air pollution with aerodynamic diameter≤ 2.5 μ m (PM
2.5) is an important contributor to the global burden of disease. Information on the shape of …

Background Both short-and long-term exposures to fine particulate matter (≤ 2.5 μm; PM2.
5) are associated with mortality. However, whether the associations exist at levels below the …
