Short summary
We present a new global model to simulate the atmospheric transport of toxic contaminants (PCBs). We evaluate the model against PCB observations in the northern hemisphere midlatitude and Arctic atmosphere. We then use the model to calculate global budgets of PCBs and to examine the influence of climate- and emissions-driven processes on Arctic atmospheric concentrations. We find that processes occurring outside the Arctic have a greater influence on Arctic PCBs than those occurring within.
