SOOT-SEA : Impact of Black Carbon in South East Asia

The scientific objectives of the project SOOT-SEA

the objectives of this study in northern Vietnam are to determine:

• (1) the composition of fine particles in order to assess their health, climatic and environmental impacts,
• (2) their origin, both geographical and sectoral,
• (3) atmospheric deposition fluxes,
• (4) fluvial fluxes of black carbon towards the ocean.

Study carried out during a complete annual cycle (weekly frequency). Aerosols were sampled for 24 hours using a large volume PM2.5 collector.

Samples collected on quartz filters were analyzed to determine the concentrations of:

• organic carbon (OC) and
• elemental carbon (EC),
• organic nitrogen (ON),
• metals (Hg, Al, Ti, V, Cr, Mn, Fe, Co , Ni, Cu, Zn, As, Ag, Cd, Sn, Sb, Cs, Ce, Nd, Pb, U),
• Pb isotopes,
• PAHs, sugars, ions, organic acids, humic-like substances (HULIS). The oxidizing potential (OP) of these particles was determined using the DTT (Dithiotreithol) method.
