ABSTRACT Imperial Valley, California has become increasingly hot, dry, and polluted over
the past decade. Particulate matter (PM) levels are amongst the highest in this State …

Particulate matter (PM) elicits inflammatory and toxic responses in the lung specific to its
constituents, which can vary by region, time, and particle size. To identify the mechanism of …

Epidemiologic studies have shown that airborne particulate matter (PM) with a mass median
aerodynamic diameter< 10 microm (PM10) is associated with an increase in respiratory …

An inhalation exposure study for particulate matter (PM) investigates links between
exposure and observed changes in respiratory function by evaluating the interactions of …

A collaborative research study was conducted in order to improve our understanding of the
source-to-receptor pathway for ambient fine particulate matter (aerodynamic diameter≤ 2.5 …

Background Increases in ambient particulate matter of aerodynamic diameter of 2.5 μm (PM
2.5) are associated with asthma morbidity and mortality. The overall objective of this study …

Coarse and fine particulate matter (PM2. 5–10 and PM2. 5, respectively) are regulated
ambient air pollutants thought to have major adverse health effects in exposed humans. The …

The EPA regulates ambient particulate matter (PM) because substantial associations have
been established between PM and health impacts. Presently, regulatory compliance …

Although significant progress has been made over the past few years, there is still debate on
the causal fractions that are responsible for particulate matter (PM)-associated adverse …

Airborne particulate matter (PM) is hypothesized to play a role in increases in asthma
prevalence, although a causal relationship has yet to be established. To investigate the …
