Chemical characterization of individual aerosol particles in central Siberia
Article Abstract:
Over 120 samples of Siberian aerosol collected at two sampling stations in central Siberia in Feb. and Aug. 1992 were subjected to single-particle analysis for chemical characterization. Four hundred particles for each sample were analyzed and nine major particle types were determined. Differences in aerosol composition were larger between the winter and summer campaigns than between the two sampling locations. Significant differences in abundances for the major particle types for different source sectors were noted. Results show proof that industrial complexes in the former Soviet Union contribute to Arctic pollution.

Use of an iridium tracer to determine the size distribution of aerosol emitted from a fleet of diesel sanitation trucks
Article Abstract:
Motor vehicles, particularly those with diesel engines, are the largest contributors of soot which lead to to mutagenicity and carcinogenicity of urban aerosol particles. An iridium tracer was employed to assess the size distribution of soot discharged by a fleet of diesel sanitation trucks used by Baltimore city. Iridium was shown to be an efficient indicator of soot and stressed the need for the development of a unique tracer in order to substantiate research on urban soot aerosol.

Characterization of antarctic aerosol particles using laser microprobe mass spectrometry
Article Abstract:
Aerosol particles collected from the Antarctic with a multi-stage high volume sampler were analyzed using reflection-type laser microprobe mass spectrometry. It was shown that aerosol particles in the Antarctic region were subject to seasonal variations in solar radiation and that they underwent an abnormal increase during the March-April period. The results suggested the possibility of soil particle transport from outside the Antarctic during winter.
