PM2.5 and its Ion Composition Emitted form Biomass Burning in Open-System Combustion Chamber

Open burning is the main contributor of air pollution in South East Asia. This work aims to determine PM2.5 (particulate matter with a diameter ≤ 2.5 μm) and its ion composition emitted from biomass burning. Biomass samples (rice straw, maize residue and leaf litter) were burned in the open-system combustion chamber. PM2.5 samples were collected and analyzed for its ion composition. Result can be used to estimate emission of air pollutants from open burning. Keywords- Biomass Burning; PM2.5; Ion Composition; Air Pollution; Combustion Chamber
