GEM/POPs: a global 3-D dynamic model for semi-volatile persistent organic pollutants ? Part 2: Global transports and budgets of PCBs
International audience Global transports and budgets of three PCBs were investigated with a 3-D dynamic model for semi-volatile persistent organic pollutants ? GEM/POPs. Dominant pathways were identified for PCB transports in the atmosphere with a peak transport flux below 8 km and 14 km for gaseous...
