| Abstract: | Since its being developed in 1993, great progress has been made in the application of positive matrix factorization (PMF) in source apportionment of persistent toxic substances (PTS), especially in that of polycyclic aromatic hydrocarbons (PAHs). In this article, the basic principle of PMF was introduced first, and then its applications in source apportionment of PAHs distributed in soil/sediment, atmosphere and water were reviewed. In addition, the prospects of PMF in source apportionment of PAHs distributed in different environmental media were described based on our recent experimental results. |
