[Study of heavy metal immission with dust sedimentation in various regions of the GDR. Results of a nationwide study of 144 measuring points (1983-1988)].
Dust sediment samples had been taken continuously from 1983 to 1988 in the environment of trace element emitting industrial plants, in industrial centers, in urban regions without specific deposits, and in background regions of the GDR. After wet digestion the concentrations of 17 elements (Ca, Fe, Al, Mg, Na, P, Zn, Mn, Ti, Ba, Pb, Sr, Cu, Cr, Cd, V, Be) have been determined by atomic emission spectrometry (ICP) and calculated as element fallout (mg/m2 x 30 d). More than 60,000 data underlie statistical analysis. Measuring points with geometrical averaged immissions of significant elements (Zn, Cu, Pb, Cd, Be, Cr, V) above the 84-percentile of all measuring points are listed separately. Very heavy sources of all analysed elements are steel plants more than nonferrous metal plants. The northern territories of the GDR are comparatively slightly impacted.
