Epidemiological studies have consistently shown associations of exposure to ambient
particulate matter (PM) with severe health effects, including mortality and hospitalization, in …

Many epidemiologic reports associate ambient levels of particulate matter (PM) with human
mortality and morbidity, particularly in people with preexisting cardiopulmonary disease (eg …

We review literature that provides insights on health-related effects observed in laboratory-
based inhalation studies in humans and laboratory animals using concentrated ambient air …

Results from epidemiology studies have shown statistical associations between ambient air
particulate matter (PM) concentrations and mortality/morbidity, particularly among …

Background: Data from a previous study conducted in Baltimore, MD, showed that ambient
fine particulate matter less than 2.5 μm in diameter (PM 2.5) concentrations were strongly …

Air pollution epidemiologic studies use ambient pollutant concentrations as surrogates of
personal exposure. Strong correlations among numerous ambient pollutant concentrations …

While most in the scientific community are of the opinion that the composition of fine
particulate matter (PM2. 5) is an important driver of resultant health effects, there is still some …

Results of recent research show that particulate matter (PM) composition and size vary
widely with both space and time. Despite the variability in PM characteristics, which are …

Recent epidemiological studies have shown an association between daily morbidity and
mortality and ambient particulate matter (PM) air pollution. It has been proposed that …

To provide additional insight into factors affecting exposure to airborne particulate matter
and the resultant health effects, we developed a method to estimate the ambient and …
