PARTICLE-BOUND DECHLORANE PLUS IN THE ATMOSPHERE OF HARBIN,CHINA
Seventeen air samples were collected using a high-volume air sampler during May to August, 2008 in Harbin, China for measuring Dechlorane plus (DP) concentrations in air. Both particulate and gaseous phase air were collected, however only particulate phase DP was detected. The average total concentrations of DP (syn plus anti) was 0.35 ± 0.21 pg m-3, which is lower than that of the Great Lakes region. The anti-DP was consistently greater than that of the syn isomer. The average fractional abundance (fsyn) was very close to the technical DP composition according other studies in the Great Lakes region, which indicates that there may be some new sources in this study region and further research is needed to better understand the behavior of DP in China. As we know, this study is the first attempt to measure exact atmospheric DP concentrations in China.
