Total Potential Source Contribution Function Analysis of Trace Elements Determined in Aerosol Samples Collected near Lake Huron
journal contribution
posted on 2004-08-15, 00:00 authored by S. R. Biegalski, P. K. HopkeAerosol samples were collected at the rural Burnt Island
Ontario Integrated Air Deposition Network air sampling station
on the northern shore of Lake Huron from 1992 through
1994. The samples were analyzed for trace elements by
neutron activation analysis, and the air concentrations of
over 30 elements were determined. Total potential
source contribution function analysis (TPSCF) was used
to determine the most probable geographical location of
these aerosols' origin. The TPSCF results for As, In, Sb, Se,
Sn, and Zn are highlighted in this paper. Source regions
for these elements ranged from Alma, Quebec, Canada to
Carrollton, GA. Because of large seasonal variations in
the concentrations of the atmospheric concentrations of
these elements, TPSCF values were calculated for the summer
and winter halves of the year as well as the entire year.
