Vietnam biomass burning - Application of Comprehensive Time of Flight gas chromatography for chemical characterization of environmentally and health -dangerous emissions in urban and biomass burning regions in Vietnam

Southeast Asia is well-known for emission-intense and recurring wildfires and after-harvest crop residue burning during the pre-monsoon season from February to April. This project seeks to monitor biomass burning (BB) plumes arriving at remote Pha Din meteorological station (Northwest Vietnam), outline its carbonaceous particulate matter (PM) constituents based on a molecular marker approach and discuss possible BB sources to adds valuable information on chemical PM composition for a region with scarce data availability. Furthermore, laboratory-burning of rice and wheat straw and smog chamber-based ageing of the combustion emissions is performed to investigate their photochemistry and secondary organic aerosol formation potential under different NOx regimes.
