Rationale: A large body of epidemiologic literature has found an association of increased
fine particulate air pollution (PM2. 5) with acute and chronic mortality. The effect of …

Rationale: There is compelling evidence that acute and chronic exposure to ambient fine
particulate matter (PM2. 5) air pollution increases cardiopulmonary mortality. However, the …

Rationale: Evidence concerning the acute health effects of air pollution caused by fine
particulate matter (PM2. 5) in developing countries is quite limited. Objectives: To evaluate …

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 Air pollution in cities has been linked to increased rates of mortality and
morbidity in developed and developing countries. Although these findings have helped lead …

BACKGROUND Epidemiologic time-series studies conducted in a number of cities have
identified, in general, an association between daily changes in concentration of ambient …

Rationale: The associations between ambient coarse particulate matter (PM2. 5–10) and
daily mortality are not fully understood on a global scale. Objectives: To evaluate the short …

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

Rationale: There are unexplained geographical and seasonal differences in the short-term
effects of fine particulate matter (PM2. 5) on human health. The hypothesis has been …

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 …
