While numerous studies have demonstrated that shortterm exposure to particulate matter
(PM*) is associated with adverse health effects, the characteristics of PM that cause harm …

Background: Fine particulate matter (PM2. 5) air pollution exposure has been identified as a
global health threat. However, the types and sources of particles most responsible are not …

Background The health effects of particulate air pollution are widely recognized and there is
some evidence that the magnitude of these effects vary by particle component. We studied …

Few studies on size-specific health effects of particulate matter have been conducted in
Asia. We examined the association between both fine and coarse particles (PM 2.5 and PM …

Background Several studies have reported associations between long-term exposure to
ambient fine particulate matter (PM) and cardiovascular mortality. However, the health …

Epidemiologic studies of the link between particulate matter (PM) concentrations and
mortality rates have yielded a range of estimates, leading to disagreement about the …

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 …

BACKGROUND: In recent years, numerous reports demonstrating the relationship between
an increase in the concentration of fine particulate matter (PM2. 5) and daily mortality have …

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 The link between PM 2.5 exposure and adverse health outcomes is well
documented from studies across the world. However, the reported effect estimates vary …
