Abstract

|
Objectives: Pine needles are used as passive air samplers (PAS) of atmospheric persistent organic pollutants (POPs). This study was carried out in order to investigate whether pine needles can also be used as a PAS of polybrominated diphenyl ethers (PBDEs).
Methods: PBDEs in one to three year-old pine needles were analyzed with HRGC/HRMS.
Results: PBDEs in the atmosphere were accumulated in the pine needles. The rate of increase in concentration of lower substituted PBDEs (tri- through hepta-) in pine needles was linear. The rate of increase of the higher substituted PBDEs (octa- through deca-) was also liner, but only up to two year-old pine needles. The concentration did not increase further in older pine needles.
Conclusion: Therefore, it can be concluded that young pine needles, those that are two years old or less, are recommended for use as PAS of atmospheric PBDEs.
