ABSTRACT
The positive matrix factorization (PMF) and the chemical mass balance (CMB) models were applied to the source apportionment of ambient PM study for a coastal industrial area. The PMF result for coarse fraction was similar to that of the CMB model. As for coarse fraction, correlation coefficients for the calculated contributions by the PMF and CMB models for individual samples were larger than 0.6 for the source categories of sea salt, soil and steel mill. As for the fine fraction, the PMF could also identify the following emission sources: steel mill, soil, Cl and NO3 rich secondary particle, aged sea salt, SO4 rich secondary particle, and refuse burning. However the CMB result for fine fraction was not satisfactory due to higher ratio of secondary particles.
