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.

일본 관동지역을 대상으로 PCBs의 대기 중 거동을 해석하기 위해 단일 구획상자모델을 사용하였으며, 대기 중 기온과 PCBs의 각 동족체의 거동사이의 관계를 시뮬레이션하였다. 또한 모델을 이용하여 대상 지역에 있어서의 PCBs의 년간 배출량과 침적량을 추산하였으며, 년간 배출량은 3,320 kg, 년간 침적량은 1,480 kg으로 예측되었다. 대기 중 PCBs의 제거기작(이류, 건성-습성 침적 및 반응) 중 이류의 기여는 전체의 약 $20{\sim}38%$로 나타났으며, OH라디칼 반응에 의한 감소는 무시할 정도로 작았다. 본 연구에서 사용한 단일 구획상자모델이 대기 중 PCBs의 거동을 이해하는데 활용될 수 있을 것으로 생각된다.
