Modeling incorporation and post-depositional processes of PCB in Alpine glaciers

A model describing (1) the transport from source areas in the lowlands to Alpine areas (2) the deposition to the glacier surface by dry deposition and wet deposition in form of snow or rain and (3) the incorporation and storage at the glacier surface including the partitioning between the solid ice matrix pore air organic particles and liquid water is presented. The model is validated with the concentration records measured in an ice core from a cold glacier (Fiescherhorn CH) and from a temperate glacier (Silvretta CH).
