영문 초록

Objective: This study was carried out to use pine needles as a passive air sampler (PAS) for atmospheric polychlorinared dibenzo-p-dioxins/furans (PCDD/Fs). Methods: PCDD/Fs concentrations in ambient air (C a , pg/m 3 ) and deposited pine needles (C p , pg/g dry) were analyzed simultaneously from June 1 to December 31. Air samples were taken using two low volume PUF active air samplers with an overall average air volume of approximately 1,200 Sm 3 . Pine needles were collected the end of December near the air sampler. PCDD/Fs was analyzed by HRGC/HRMs. Results: A good correlation was shown (R 2 =0.6357, p=0.0001) between C a and C p , but a better correlation (R 2 =0.7372, p<0.0001) existed between the logarithm of octanol-air partitioning coefficient (LogK oa ) and Log(C p /C a ). The average PCDD/Fs sampling rates from air to pine needles were 0.045(0.018-0.185 m 3 /day-g dry). Conclusion: It was found that pine needles can be used as PAS for atmospheric PCDD/Fs, and they are especially suitable for long time PAS compared to PUF disk PAS.
