Greenpeace Southeast Asia ranked Chiang Mai as the most polluted city in 2016 in terms of PM2.5 pollution[1]. PM2.5 contains various pollutants, including Polycyclic Aromatic Hydrocarbons (PAHs), leading to adverse human health effects [2], [3].
This PhD project aims to identify the source and processes of PAHs during the local agricultural burning periods (March to April), and non-burning period (May to June) in 2019 at an urban background site, which is 10 km away from the Chiang Mai city centre.
