- Cooking oil fumes can increase the chances of developing lung cancer
- Cooking organic aerosol (COA) is one of the highest contributing factors of pollution in metropolitan environments
A new method which can help trace the cooking pollution found. This method could help developing countries to keep unstable levels at check.
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.
"Considering that ACSM has been increasingly deployed worldwide for routine measurements of aerosol particle composition, our study might have significant implications for better source apportionment of OA and exposure studies in the future." Said Prof. Sun.
