To determine the size distribution and chemical composition of
particles directly emitted from selected sources: agricultural burning,
soils, crude oil combustion, diesel trucks, paved and unpaved roads,
residential wood combustion, sand and cinder storage dust, and unpaved
Findings: Chemical profiles were developed for each of the sources in
seven particle size categories and total suspended particulate.
Chemical analyses were conducted for 43 different chemical species.
Importance to ARB’s Program:
The results of this study were used to relate source contributions to
measured particulate concentrations in the atmosphere to provide
insight into the environmental and human health impacts of specific
sources, and for attainment of the State and Federal ambient air
quality standards for particulate pollution (PM10).
