Sampling location
Research frame • Carbon based particulate emissions are an important anthropogenic pollutant source in Arctic settlements and towns associated with PAH pollution. • Emission profiles and distribution properties of atmospheric particles poorly understood. • Particle associated pollutants (e.g. PAHs, soot, Dioxins, etc.) are emitted. • Research on particles as efficient transport vehicles for transport of semi-volatiles needs priority. • The particle fraction associated with PAH emissions is poorly investigated for Arctic sources.

UNIS is funding the PAH project of Tatiana Drotikova. The UNIS logistical department as as well as the Arctic technology department were instrumental in the organisation of the field work. The support of the engineers and personal of the Russian and Norwegian Power plants in Svalbard is highly appreciated
Discussion Emission properties (e.g. temperature, water content etc) are governing particle characterisation and PAH distribution. PAH patterns are obviously associated with coarse fraction (aerodynamic diameter > 0.5 µm), GFF cut-off 10 µm. Indication for fly ashes and carbon association for PAH emissions are found. Method coordination and adoptions is required for a more quantitative approach
