Epidemiologic cohort studies have consistently demonstrated that long-term exposure to
ambient fine particles (PM2. 5) is associated with mortality. Nevertheless, extrapolating …

Background: Epidemiologic studies have reported associations between fine particles
(aerodynamic diameter≤ 2.5 µm; PM2. 5) and mortality. However, concerns have been …

Background: Exposure to ambient fine particulate matter (PM 2.5) has been linked with
premature mortality, but sources of PM 2.5 have been less studied. Methods: We evaluated …

Background: Few cohort studies have evaluated the risk of mortality associated with long-
term exposure to fine particulate matter [≤ 2.5 μm in aerodynamic diameter (PM2. 5)]. This is …

Background Understanding the shape of the relationship between long-term exposure to
ambient fine particulate matter (PM 2.5) concentrations and health risks is critical for health …

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 …

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 …

Many studies have reported associations between daily particles less than 2.5 µm in
aerodynamic diameter (PM2. 5) and deaths, but they have been associational studies that …

Exposure to fine particulate matter (PM2. 5) is associated with increased mortality. Although
epidemiology studies typically use outdoor PM2. 5 concentrations as surrogates for …

Fine particulate air pollution has been associated with increases in long-term mortality in
selected cohort studies, and this association has been influential in the establishment of air …
