The objectives of this study were to determine whether differences in the size and
composition of coarse (2.5-10 micro m), fine (< 2.5 microm), and ultrafine (< 0.1 microm) …

Particulate pollutants cause adverse health effects through the generation of oxidative
stress. A key question is whether these effects are mediated by the particles or their …

Adverse health effects of urban air pollution particulates may be attributable to particle
mediated oxidant stress and inflammation. Intracellular oxidant production in normal …

Background Although the mechanisms of airborne particulate matter (PM) related health
effects remain incompletely understood, one emerging hypothesis is that these adverse …

Epidemiological studies demonstrated an association between increased levels of ambient
air pollution particles and human morbidity and mortality. Production of oxidants, either …

Epidemiological and toxicological studies have suggested that the health effects associated
with exposure to particulate matter (PM) are related to the different physicochemical …

The mechanisms for increased cardiopulmonary disease in individuals exposed to
particulate air pollution are associated with fine and ultrafine particles that have a high …

Epidemiological studies demonstrate associations between increasing levels of ambient
particles and morbidity in the elderly with cardiopulmonary disease. Such findings have …

Exposure to ambient air pollution particles (PM) has been associated with increased
cardiopulmonary morbidity and mortality, particularly in individuals with pre-existing disease …

In ambient aerosols, ultrafine particles (UFP) and their agglomerates are considered to be
major factors contributing to adverse health effects. Reactivity of agglomerated UFP of …
