Air particulate matter has been associated with adverse impact on the respiratory system
leading to cytotoxic and proinflammatory effects. The biological mechanisms behind these …

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

Asthma, the most common chronic respiratory disease in children, affects numerous people
worldwide. Accumulating evidence suggests that exposure to high levels of particulate …

Background Proximity to traffic-related pollution has been associated with poor respiratory
health in adults and children. Objectives We wished to test the hypothesis that particulate …

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

Studies into the effects of ultrafine particles in the lung have shown adverse effects
considered to be due in part to the particle size. Air pollution particles (PM10) are associated …

Ambient air pollution is composed of a heterogeneous mixture of gaseous and solid particle
compounds in which primary particles are emitted directly into the atmosphere, such as …

In the lower airways, macrophages are important regulators of inflammation and
indispensable in their antimicrobial activities. Thus, air pollution particles, which modulate …

Epidemiological studies continue to indicate associations between exposure to increased
concentrations of ambient fine and ultrafine particles and adverse health effects in …

Ambient particulate matter (PM) originates from a range of sources and differs in
composition with respect to season, time of day, and particle size. In this study, ambient PM …
