Accumulation of heavy metals concentration in contaminated soil before sowing and after harvesting of Rice (Oryza sativa L.) crops as well as vermicompost of different animal dung and in earthworm body were determined. The heavy metal concentration of Co, Cr and Pb were observed significant (P<0.05) % decreased in final vermicompost with respect to initial feed mixture of different animal dung. The earthworm Eisenia fetida is a suitable species for vermicomposting and accumulation of heavy metals from biological wastes and soil. The application of vermicompost and use of Eisenia fetida in rice field soil which remediate the toxic heavy metal from wheat grains and beneficial for human, animal and environment. T maximum amount of Cobalt (Co) was observed to decrease in combination of soil with cow dung vermicompost inoculed with earthworm E. fetida 44.04% wheaeas, the maximum Cromium (Cr) decrease in horse dung with soil 17.20% and lead (Pb) in combination of soil with goat dung 32.72%. The significant heavy metal accumulation of Co, Cr and Pb were observed to decrease in final vermicompost of animal dung and in wheat grain.
