Geoökologische Untersuchungen zur Schwermetallbelastung städtischer Kleingärten in Halle/Saale

Abstract

First examinations at the Institute for Geography, University Halle-Wittenberg, show that the soils of gardens in the city of Halle generally are not polluted or "noxious" [DIABY et ZIERDT (1993), FRÜHAUF at al. ( 1993)]). As a result it can be stated that in few cases today's official limits for soils and plants are exceeded. These sites - often single gardens - are located on former most natureous refuse tips. They should be rehabilitate through mixing with unstressed mother earth. This paper special explain and discuss the reasons and mechanism of heavy metal "contents".
