Removal of Decachlorobiphenyl in Vermicomposting Process Amended with Rabbit Manure and Peat Moss

摘要: This study aimed to evaluate the removal of polychlorinated biphenyls, with a vermicomposting system, using following as components: earthworm Eisenia fetida, peat moss and rabbit excrement compound called decachlorobiphenyl, for period 91 days under non-sterile conditions. The results obtained were decachlorobiphenyl 79.6 % an initial concentration 100 mg L−1, 89.7 150 L−1 95.38 200 L−1; earthworms bioaccumulated less than 5 in all concentrations analysed without apparent toxic effect. Weight gain was observed that assimilated contaminant during vermicomposting, number cocoons produced contrast control which both weight lower. To our knowledge, this is first suggests may be suitable mechanism high recalcitrance from contaminated sediment or soils.
