Background Health effects associated with air pollution are typically evaluated using a
single pollutant approach, yet people are exposed to mixtures consisting of multiple …

Polycyclic aromatic hydrocarbons (PAHs) are widely present in the environment. The coking
industry is an important industrial source of PAHs. Coke production in China accounts for …

Two commonly used receptor models, positive matrix factorization (PMF) and chemical mass
balance (CMB), are applied to 3-year PM2. 5 data at two urban sites (Atlanta, GA and …

Elemental potassium has been extensively used as an indicator of biomass burning in the
source apportionment of PM 2.5. We present a method to estimate the fraction of potassium …

Abstract Heavy metals (Cr, Co, Ni, As, Cd, and Pb) can be bound to PM adversely affecting
human health. Quantifying the source impacts on heavy metals can provide source-specific …

Source apportionment of particulate matter (PM) has been carried out for the city of
Hyderabad using the chemical mass balance model (CMB8, Ver. 8.0) in PM10 and PM2. 5 …

Abstract In 1998, the US Environmental Protection Agency (EPA) initiated a major air quality
program known as the Particulate Matter (PM) Supersites Program. The Supersites Program …

Wind erosion of soil is one of the most important sources of atmospheric particulate matter
(PM). Determining the contribution of wind erosion of soil to the concentration of atmospheric …

The instability of a receptor model due to nearly collinear sources is often worsened by a
large number of unknown sources, which usually results in unacceptable source …

Estimating the relative contributions from multiple potential sources of a specific component
in a mixed environmental matrix is a general challenge in diverse fields such as …
