Persistence, bioaccumulation, toxicity and transfer to surface and ground waters are key issues when pollutants enter the soil environment. Their fate is influenced by the dynamics of sorption, binding and remobilization processes in function of time and space. These processes are influenced by changing soil management systems e.g. till, no till, mulch systems, and organic amendments like biochar. Contributions to explain the changing capacity of the soil microflora to degrade pollutant molecules are as well most welcome.
The session will promote a better understanding of the disparity between persistence values of compounds tested at laboratory and field scales and tackle the elucidation of processes resulting in persistence or mobilization within the soil matrix. Biological, chemical as well as physicochemical process understanding addressed integratetively are of particular interest.
