| Research Abstract |
Current pollution status of harmful chlorinated organic compounds and heavy metals in sediments and soils were investigated in the Mekong basin in Vietnam. In the investigation area, several points were polluted locally with those chemicals, but most of them were washed away by annual flooding. Remediation experiments of contaminated sediments and soils by γ-BHC (Linden), which was a representative of the harmful chlorinated organic compounds, were carried out by adding iron powder or pyrite in experimental system. Linden in the soils and sediments were apparently degraded by addition of these materials.
