Identification of individual aerosol particles containing Cr, Pb, and Zn above the North Sea

摘要: Aerosol samples have been collected over the southern bight of North Sea from an aircraft. In this way, 96 were taken for single-particle analysis during 16 flights. Almost 45 000 individual particles analyzed with electron probe X-ray microanalysis. More than 5000 these found to contain significant concentrations one or more heavy metals Cr, Pb, and Zn. With help hierarchical, nonhierarchical, fuzzy clustering techniques, various metal-containing particle types could be identified. Significant differences in abundances detected metal aerosol, depending on origin air masses. continental influence 50 times Zn- Pb-containing a marine history. For other hand, we sector that one-third values sectors. This might point rather undefined source, which recycling ...
