Abstract

Polychlorinated biphenyls(PCBs) and polybrominated diphenyl ethers (PBDEs) were measured in pine needles of Seoul, and Ansung(GyeongGi-do) to investigate composition, source, and regional concentration of PBDEs. Concentration of total PCBs in Seoul and Ansung showed 608, 945 pg/g DW (mean: 777 pg/g DW), respectively, also concentration of total PBDEs(pg/g DW) in Seoul and Ansung showed 7944, 14,255 pg/g DW(mean 11,100 pg/g DW). Tetrachlorinated biphenyls(Tetra-CBs) and Decabromodiphenyl ethers (Deca-BDE) were detected in relatively high concentration compared to other PBDE congeners in Seoul and Ansung. Correlation coefficients(r) of between PCB congeners in pine needles detected of Seoul and Ansung were significant (r=0.85, p<0.01). It suggested that PCBs concentration in pine needles may originate from secondary sources such as air-plant partition. The similarity of between PBDE congeners profile to those of the technical mixture formulation (Bromkal 70-5DE) suggests a source of this product in these sites.
