| Outline of Final Research Achievements |
We analyzed over 80 inorganic and organic components of PM2.5 during a 1-year sampling campaign in Malaysia. Intensive field studies were also conducted at peatland fire sites in Indonesia during the fire episode. These studies demonstrated the different chemical characteristics of PM2.5 at the source and receptor sites. Based on the analytical data, we proposed a new key indicator of Indonesian peatland fire (IPF), and secondary formation of some PAH derivatives was suggested for the haze samples associated with the peatland fire during their atmospheric transport. Furthermore, we firstly revealed that IPF contributed to nearly 30% of the annual average PM2.5 concentration in Malaysia by Positive Matrix Factorization model. In addition, we found significant correlations between biological effects and concentrations of some PAH derivatives of the haze samples. These results suggest that those components have the potential to worsen respiratory diseases.
