Cooking organic aerosol (COA) is one of the most important primary sources of pollution in urban environments. There is growing evidence that exposure to cooking oil fumes is linked to lung cancer. Currently, the most effective method to identify and quantify COA is through positive matrix factorization of OA mass spectra from aerosol mass spectrometer measurements. However, for the widely used low mass resolution aerosol chemical speciation monitor (ACSM), it is often challenging to separate COA from traffic-related organic aerosol (HOA) due to the similarity of their unit mass resolution spectra.
