Abstract: | The impacts of contact time on the extractability, the availability of hexachlorobenzene (HCB) in dierent soils (paddy soil, red soil, and uvo-aquic soil) and bioaccumulation in earthworm Eisenia foetida were investigated under controlled conditions in laboratory. Results indicated that the aging rate of HCB displaying a biphasic character in dierent soils: a rapid aging in the first 60 d followed by a slow aging in the next 120 d incubation time. Moreover, most of extractable HCB (about 90%) decline occurr... |
