Epidemiologic research has shown increases in adverse cardiovascular and respiratory
outcomes in relation to mass concentrations of particulate matter (PM)≤ 2.5 or≤ 10 μm in …

Numerous epidemiologic time-series studies have shown generally consistent associations
of cardiovascular hospital admissions and mortality with outdoor air pollution, particularly …

Background: There is growing evidence that exposure to ultrafine particles (UFP; particles
smaller than 100 nm) may play an underexplored role in the etiology of several illnesses …

Background Exposure to fine ambient particulate matter (PM) has consistently been
associated with increased morbidity and mortality. The relationship between exposure to …

At present there is no clear epidemiological evidence linking adverse human health effects
to ultrafine particles (UFP), arguably because there is no universally agreed upon UFP …

Abstract Introduction and Objectives: Recent epidemiological studies have shown an
association between increased particulate urban air pollution and adverse health effects on …

Toxicological studies have provided evidence of the toxicity of ultrafine particles (UFP), but
epidemiological evidence for health effects of ultrafines is limited. No quantitative summary …

Human exposures to ultrafine particles (UFP) are poorly characterized given the potential
associated health risks. Residences are important sites of exposure. To characterize …

Methods to characterize chronic exposure to ultrafine particles (UFP) can help to clarify
potential health effects. Since UFP are not routinely monitored in North America …

Objectives Due to their small size, ultrafine particles (UFP) are believed to exert higher
toxicity than larger particles. As numerous studies on health effects of UFP have been …
