A new method which can help trace the cooking pollution found. This method could help developing countries to keep unstable levels at check.
highlights
- 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

Recently, Prof. Yele Sun and his team at the Institute of Atmospheric Physics, Chinese Academy of Sciences, found that black carbon (BC) is a good tracer to separate HOA and COA. By applying the BC tracer method to several datasets in megacities of Beijing and Nanjing, they found that COA contributed 15-27% to total organic aerosol in summer and even more than 10% during heating period with a significant enhancement of coal combustion emissions. COA is also an important contribution of OA in urban areas globally, on average contributing 15-20%. Their studies suggest that air quality improvements in developing countries could benefit substantially from the reduction of cooking emissions.
"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.
