Several studies conducted in US cities report an association between acute exposures to
particulate matter (PM), usually measured as PM10, and mortality. Evidence of high …

Background: Several studies have demonstrated associations between daily mortality and
ambient particulate matter less than 2.5 microns in diameter (fine particles or PM2. 5). Few …

Numerous studies have reported weak but statistically significant acute health effects of
particulate air pollution. The associations are observed at levels below the current US …

We evaluated the association between mortality outcomes in elderly individuals and
particulate matter (PM) of varying aerodynamic diameters (in micrometers)[PM (10), PM …

This study was undertaken to determine whether variations in concentrations of particles in
the ambient air of Montreal, Quebec, during the period 1984 to 1993, were associated with …

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 …

Substantial evidence supports an association of particulate matter (PM) with
cardiorespiratory illnesses, but little is known regarding characteristics of PM that might …

Background Approximately 2.9 million deaths are attributed to ambient fine particle air
pollution around the world each year (PM 2.5). In general, cohort studies of mortality and …

Increased mortality has been observed in association with elevated concentrations of air
pollutants in European cities and in the United States. We reassessed the effects of …

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 …
