Previously we reported that fine particle mass (particulate matter [less than and equal to] 2.5
microm; PM (2.5)), which is primarily from combustion sources, but not coarse particle mass …

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 …

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: Epidemiological studies have examined the association between PM2. 5 and
mortality, but uncertainty remains about the seasonal variations in PM2. 5-related effects and …

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 …

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

Although some consensus has emerged among the scientific and regulatory communities
that the urban ambient atmospheric mix of combustion related pollutants is a determinant of …

Many epidemiological studies provide evidence of an association between ambient
particles, measured as PM10, and daily mortality. Most of these studies have been …

Recent epidemiologic studies have consistently reported increased daily mortality
associated with exposures to particulate air pollution. Currently, particulate mass is …

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