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 …

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 …

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 …

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 …

Particulate matter (PM*), an ambient air criteria pollutant, is a complex mixture of chemical
components; particle sizes range from nanometer-sized molecular clusters to dust particles …

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

In 1998 Congress mandated expanded US Environmental Protection Agency (US EPA)
health effects research on ambient air particulate matter (PM) and a National Research …

Recent epidemiological studies have consistently shown that the acute mortality effects of
high concentrations of ambient particulate matter (PM), documented in historic air pollution …

Background: Although the association between PM2. 5 mass and mortality has been
extensively studied, few national-level analyses have estimated mortality effects of PM2. 5 …

Background Several studies have reported associations between long-term exposure to
ambient fine particulate matter (PM) and cardiovascular mortality. However, the health …
