Background The systematic evaluation of the results of time-series studies of air pollution is
challenged by differences in model specification and publication bias. Methods We …

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 …

China is one of the few countries with some of the highest particulate matter levels in the
world. However, only a small number of particulate matter health studies have been …

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 …

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 …

Objectives To estimate the short term effect of particulate air pollution (particle diameter< 10
μm, or PM 10) on mortality and explore the heterogeneity of particulate air pollution effects in …

Background: Coarse particulate matter with aerodynamic diameter between 2.5 and 10 μ m
(PM 2.5–10) air pollution is a severe environmental problem in developing countries, but its …

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

Few prior cohort studies exist in developing countries examining the association of ambient
particulate matter (PM) with mortality. We examined the association of particulate air …
