title: Dechlorane Plus and decabromodiphenyl ether in atmospheric particles of northeast Asian cities.
abstract: Atmospheric particles were collected in several cities in Japan (Sapporo, Sagamihara, Kanazawa, and Kitakyushu), Korea (Busan), and China (Beijing) using a high-volume air sampler equipped with a quartz fiber filter. The summer and winter samples were analyzed using gas chromatography-high-resolution mass spectrometry for Dechlorane Plus (DP). Decabromodiphenyl ether (BDE-209) was also analyzed for the samples from Kanazawa and Beijing. DP was detected in all samples. The mean total DP (ΣDP) concentration was highest (6.7 pg/m(3)) and lowest (0.87 pg/m(3)) in the winter samples from Sagamihara and Busan, respectively. The seasonal variation of DP concentrations varied by sampling site in this study. BDE-209 was detected in all the analyzed samples except for one of the Kanazawa winter samples. BDE-209 concentration was considerably higher in Beijing than in Kanazawa. Significant correlations were found between the concentrations of ΣDP and BDE-209 in the winter samples from Kanazawa and in both summer and winter samples from Beijing. This similarity in the atmospheric behavior of DP and BDE-209, especially in winter, is assumed to reflect a common end usage and release mechanism.
