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.

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.
