Behaviour of Pesticides in Aquifer Materials: Laboratory Column Experiments

摘要

Sorption of pesticides by aquifer materials was studied by laboratory columnexperiments. Sorption was found but was always very low. Retardation factors ranged from 1 to 1.28 and K(sub om) -values are in the same order of magnitude as found for topsoils, indicating that organic matter is the most important parameter for sorption of pesticides by soils. Column experiments are favorable above batch experiments to study sorption of pesticides on aquifer materials.
