Dual carbon isotope and optical properties of black and brown carbon aerosols in E and SE Asia

Reference number
Coordinator Stockholms universitet - Institutionen för Miljövetenskap och Analytisk kemi
Funding from Vinnova SEK 600 954
Project duration April 2017 - June 2018
Status Completed

Purpose and goal

1) Mastered the experimental skills required in this project including isolation of BC and BrC, graphitization of CO2 and the determination of optical properties; 2) Determinations of levoglucosan and water-soluble ions, and the radiocarbon signals of BC aerosols; 3) Discussions of the manuscript writing with co-authors from China, Sweden, and Malaysia

Expected effects and result

1) A year-round dataset for the biomass burning tracer (levoglucosan, mannosan, galactosan), water-soluble ions, organic carbon, and BC in the PM2.5 aerosol samples collected in the regional site of SE Asia was obtained; 2) The radiocarbon signals and optical properties of BC aerosols were successfully measured; 3) The authors now are preparing the the manuscript on the source apportionment of BC in the regional site in SE Asia.

Planned approach and implementation

Determinations of dual carbon isotopes and optical properties of BC and BrC, levoglucosan, mannosan, galactosan, water-soluble ions.
