The TROICA-9 expedition (Trans-Siberian Observations Into the Chemistry of the Atmosphere) was carried out at the Trans-Siberian railway between Moscow and Vladivostok in October 2005. Measurements of aerosol physical and chemical properties were made from an observatory carriage connected to a passenger train. Black carbon (BC) concentrations in fine(More)
BACKGROUND A newly designed electrostatic precipitator (ESP) in tandem with Versatile Aerosol Concentration Enrichment System (VACES) was developed by the University of Southern California to collect ambient aerosols on substrates appropriate for chemical and toxicological analysis. The laboratory evaluation of this sampler is described in a previous paper.(More)
We studied the sources, compositions and size distributions of aerosol particles during long-range transport (LRT) PM 2.5 episodes occurred on 12–15 August, 26–28 August and 5–6 September 2002 in Finland. Backward air mass trajectories, satellite detections of fire areas, and dispersion modelling results indicate that emissions from 5 wildfires in Russia(More)
The summer of 2006 was exceptionally dry in the areas surrounding the Gulf of Finland; this resulted in frequently occurring wild land fires, especially in Russia and Estonia. The regionally transported smokes emitted by biomass burning had a strong impact on the PM 2.5 mass concentrations in The concentrations of PM 2.5 were substantially also elevated at(More)
A series of 7-week sampling campaigns were conducted in urban background sites in (summer). The campaigns were scheduled to include seasons of local public health concern due to high PM concentrations or findings in previously conducted epidemiological studies. Aerosol samples were collected in parallel with two identical virtual impactors (VI), which(More)
