Abstract

The concentrations of organic carbon(OC) and elemental carbon(EC)in total suspended particle (TSP) were investigated at Ny-Ålesund, Svalbard in a two-week campaign. The levels of OC and EC are 0.86 ± 0.27 pgm-3 (mean ± standard deviation) and 0.19 ± 0.10 /igm-3, respectively. Back trajectory analysis of air masses arriving at Ny-Ålesund reveals that long-range transport of polluted air play insignificant role in OC and EC levels, to which the potential influence of the local contamination were ascribed. The average OC/EC ratio is 5.41, suggesting the presence of the secondary organic aerosols. The estimated second' ary organic carbon (SOC) in TSP is 0.59 μg/m3. accounting for 64% Vo of the total organic carbon.
