TLDR
Inventory procedures for fine-particle trace-metals emissions are developed that assist aerosol source apportionment by receptor modeling techniques and it is shown how sparse routine air monitoring data sets on a very few trace elements can be used in chemical element balance calculations once emission inventory data have shown that avery few source signatures do complete a mass balance on those chemical elements that were measured.Abstract:
Inventory procedures for fine-particle trace-metals
emissions are developed that assist aerosol source apportionment by receptor modeling techniques. It is shown
how sparse routine air monitoring data sets on a very few
trace elements can be used in chemical element balance
calculations once emission inventory data have shown that
a very few source signatures do complete a mass balance
on those chemical elements that were measured. Methods
developed are tested in the South Coast Air Basin of
California for the year 1976, where it is shown that over
80% of the fine lead emissions comes from highway traffic,
81% of the nickel arises from fuel oil fly ash, and more
than 90% of the iron and manganese comes from soil-like
materials. With use of readily available trace element data
from local and Federal monitoring networks, it is found
that most monitoring sites are exposed to aerosol containing
about 20% highway vehicle exhaust, 1-2% fuel oil fly ash, 20-50% soil dust or road dust, with sulfates and nitrates each present at about 15% of total mass.read more

Biomass burning — a review of organic tracers for smoke from incomplete combustion
TL;DR: In this paper, a brief review of the organic matter composition in aerosols derived from the major sources is also given, with emphasis on the detection of biomass burning components, and a long range transport of smoke particulate matter with the associated organic compounds is also discussed.

PM2.5 chemical source profiles for vehicle exhaust, vegetative burning, geological material, and coal burning in Northwestern Colorado during 1995.
TL;DR: PM2.5 chemical source profiles applicable to speciated emissions inventories and receptor model source apportionment are reported for geological material, motor vehicle exhaust, residential coal (RCC) and wood combustion (RWC), forest fires, geothermal hot springs; and coal-fired power generation units from northwestern Colorado during 1995.

Source apportionment and health risk assessment of heavy metals in soil for a township in Jiangsu Province, China
TL;DR: The results indicated that Cr, Cu, Cd, Pb, Ni, and Co accumulated in the soil, attaining a mild pollution level, and both non-carcinogenic and carcinogenic risks posed by soil metals were above acceptable levels.
