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 …

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

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

Whilst epidemiological studies have consistently demonstrated adverse effects of particulate
matter exposure on human health, the mechanism of effect is currently unclear. One of the …

The fine size mode of ambient particulates, designated as PM-10, is a heterogeneous
mixture that can vary in particle size and chemical composition, depending on geographical …

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 …

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

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

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 …

While numerous studies have demonstrated that shortterm exposure to particulate matter
(PM*) is associated with adverse health effects, the characteristics of PM that cause harm …
