Abstract
To analyze atmospheric fate of PCBs in the Kanto region, Japan, an one-compartment box model was used and the relationship between behavior of each PCB homologue and air temperature was simulated. In addition, the emission rates and the deposition fluxes in the overall Kanto region were estimated by the model. The total emission rate and deposition flux was 3,320 kg/yr and 1,480 kg/yr, respectively. The contribution of advection was ranged from 22 to 38% among elimination processes(advection, dry & wet deposition and degradation) of PCBs from atmosphere. The rates of degradation(OH radical process) for PCBs in the Kanto region would be negligible. This study showed that one-compartment box model can be available to understand the overall atmospheric behavior of PCBs.
