Particulate matter (PM) is a complex, heterogeneous mixture that changes in time and
space. It encompasses many different chemical components and physical characteristics …

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

The aim of this article is to review progress toward integration of toxicological and
epidemiological research results concerning the role of specific physicochemical properties …

There is a general consensus in the scientific community that fine particulate matter (PM2. 5)
composition plays a significant role in the health effects attributed to PM; indeed …

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 …

Researchers and regulators have often considered preferentially regulating the types of
ambient airborne particulate matter (PM) most relevant to human health effects. While few …

Identifying the ambient particulate matter (PM) fractions or constituents, critically involved in
eliciting adverse health effects, is crucial to the implementation of more cost-efficient …

Exposure to particulate matter (PM) is associated with adverse health outcomes. There has
long been a question as to whether some components of the PM mixture are of greater …

Particulate matter (PM) is a key indicator of air pollution brought into the air by a variety of
natural and human activities. As it can be suspended over long time and travel over long …

Ambient air particulate matter (PM) originates as either primary particles emitted directly into
the atmosphere from a specific source or as secondary particles produced from atmospheric …
