title: [The emission of heavy metals with dust suspensions at 33 selected measuring points in the former East Germany (time period 1983-1988)].
abstract: 2200 weekly samples of airborne particulate matter from 33 measuring sites have been obtained by 12 district institutes of hygiene (Gera, Chemnitz, Leipzig, Dresden, Erfurt, Frankfurt, Magdeburg, Neubrandenburg, Rostock, Cottbus, and Berlin). After pressure digestion of the impacted membrane filters the concentrations of 15 elements (Ca, Mg, Sr, Ba, Be, Fe, Al, Ti, Cr, Mn, V, Zn, Cu, Pb, and Cd) were analysed by ICP-Spectrometry. The Immissions were calculated using the air sample volumes. Measuring points with very high immissions are: steel plant Riesa, district Dresden (nonferrous and ferrous metals), Drübeck, near to the copper plant Ilsenburg (nonferrous metals), Lead paint plant Ohrdruf, district Erfurt (highest Pb-Immission: 3137 ng/m3), Special glass plant Weisswasser, district Cottbus (Ba, Pb and Cd), Leipzig (dust and all other elements). Four groups of measuring site with different characteristic types of immissions could be distinguished by means of factor and cluster analysis. The separation of these groups by discriminant analysis was significant (P greater than 0.95). The seasonal trends showed maximal values in winter and minimal values in summer.
