Abstract
For characterization of different horizons and aquifer sediments of a podsolic soil, investigations were carried out to estimate the sorption and percolation behaviour of selected pesticides (atrazine, simazine, bromacil and lindane) and a tracer (KC1) in a fluent system with a special apparatus of glass. The aim of these experiments was to estimate the retardation (convection, dispersion, diffusion and sorption) in different substrates on the distribution of pesticides to get criteria for the assessment of pesticides in groundwater added in points or continuously into the waterflow. By this it is possible to divide pesticides with different sorption and potential degradation behaviour into endangering groups. The results showed that bromacil was the less retarded compound followed by atrazine and lindane / Available from TIB Hannover: RN 8908(93-007) / FIZ - Fachinformationszzentrum Karlsruhe / TIB - Technische Informationsbibliothek / SIGLE / Bundesministerium des Innern, Bonn (Germany) / DE / Germany
