Revealing how long-lived oil droplets could affect air pollution

The way that molecules can organise themselves into nanoscale structures may have an impact on how long pollution can stay in our cities.




Researchers from the Universities of Birmingham and Bath have used instruments at the Diamond Light Source and the Central Laser Facility to probe the behaviour of thin films of oleic acid – a material commonly released when cooking. They have used a theoretical model in combination with experimental data to predict that aerosols generated from cooking may hang around in the environment for 10 days. That's a long time for pollution to collect and disperse further afield.

The results are published in the Atmospheric Chemistry and Physics journal at acp-2021-919.pdf (
