  2. Introduction POPs monitoring by Japanese Ministry of the Environment (former Environment Agency) had continued from 1978 in the biological samples and from 1986 in the water and sediment samples until 2001. To cope with the Stockholm Convention, changing pollution levels, and the technological innovations, the activity was reframed into "POPs pollution investigation (POPs monitoring survey)" in 2002 taking into consideration the data accumulation and continuity.

  3. Methods and Materials POPs monitoring survey fiscal year 2002, -102 air samples from 34 sites, -114 water samples from 38 sites, -189 sediment samples from 63 sites, -118 biological samples from 24 sites were analyzed using HRGC/HRMS for PCBs, HCB, aldrin, endrin, DDTs, chlordanes, heptachlor, and HCHs.

  4. Acknowledgements This study was supported by POPs monitoring survey from the Ministry of Environment.
