The present project involved extensive studies on the air pollution situation and interactions between organic as well as inorganic air pollutant levels and the vegetation in three east German states. Seven monitoring sites with different emission profiles were selected in Saxony-Anhalt, one typically polluted site in Saxony, and two less polluted ...
The precipitation of heavy metals as hydroxides is the standard technique for the decontamination of waste water streams polluted by these elements. On the other side, progress in research has been made concerning the biosorption onto dead biomass and bioprecipitation supported by physiologically active bacteria. As the aim of this study, a flexibl...

Epidemiological and animal experimental studies of the fibrogenic and carcinogenic properties of natural mineral fibres in human lungs resulted in the development of man-made mineral fibres as substitutes for asbestos containing material. To evaluate the fibrogenic and neoplastic potency of man-made mineral fibres, rockwool fibres were investigated...
This work investigates the effect of ammonium nutrition (as compared to nitrate nutrition) on barley and non-micorrhized beech trees. The following parameters were investigated: growth as daily change in the biomass of shoots and roots; water-soluble constituents in leaf and root extracts; ammonium, alkali and earth alkali elements; essential inorg...
