영문 초록

Results for the concentrations of total polychlorinated biphenyls (total PCBs) and the PCB profile with different types of leaves from four coniferous trees (pine needles) at the same sampling site are presented. Concentrations of total PCBs detected in pine needles were very similar among them regardless of their different types of leaves, which means a possibility for bio-monitoring regional contamination of PCBs. Correlation coefficients(r) of PCB congeners between pine needles were very significant (r>0.97, p<0.001), which showed that PCB congener s patterns of each pine needle were similar. Profiles of PCBs detected in pine needles showed correlation with gaseous phase PCBs in air, otherwise not with particle phase PCBs in air. Therefore, it was estimated that dry gaseous deposition was a principal pathway of PCBs accumulation in pine needles. In addition, although we analyse a different types of leaves in pine needles at the same region, they can be used to identify regional contamination patterns of PCBs for larger regions.
