Dechlorane Plus is a highly chlorinated flame retardant, which was developed as an alternative of Mirex (Dechlorane), banned in the 1970s. Investigation reports are increasing rapidly recently in the United States, Canada and China. However, to our knowledge, no data for levels of Dechlorane Plus in the environment are available in Japan. Therefore, we measured Dechlorane Plus by using the GC/high-resolution MS in El mode, and identified this compound in environment samples collected from Japanese urban areas. This paper represents the first report of Dechlorane Plus in the Japanese environment. Dechlorane Plus was detected in house dust, deposits of window frames, road sediment, garden soil and sediment samples at concentrations ranging over 2.9-42 ng g(-1)-dry, 240-270 ng g(-1)-dry, 74-150 ng 1.7 ng g(-1)-dry, 17-140 ng(-1)-dry, respectively. Further we showed the mean of anti-Dechlorane Plus fractional abundance (f(anti)) values in these Japanese samples to be 0.65, 0.83, 0.80, 0.81, 0.81, respectively. The levels of Dechlorane Plus and the f(anti) values in Japan were similar to those from studies in China and Canada. Also, we noticed that care must be taken to temperature and dilution solvent to stock a high concentration of the anti-Dechlorane Plus standard solution. More research is required to elucidate the environment levels and the sources of Dechlorane Plus in Japan.
