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

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 …

This article briefly reviews evidence of health effects associated with exposure to particulate
matter (PM) air pollution from five common outdoor emission sources: traffic, coal-fired …

Exposure to ambient air particulate matter (PM) causes more mortality and morbidity than
any other regulated environmental pollutant, but PM is ill defined (US Environmental …

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

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 …

While most in the scientific community are of the opinion that the composition of fine
particulate matter (PM2. 5) is an important driver of resultant health effects, there is still some …

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

The public has long been aware that particulate matter (PM) can be deleterious to health,
between inhalation of (tobacco) smoke and “dusty” roadways. Yet establishing what PM …

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 …
