Abstract

Accumulation of heavy metals concentration in contaminated soil before sowing and after harvesting of wheat (Triticum aestivum) crops as well as vermicompost of different animal dung and in earthworm body were observed. 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 animal dung. The earthworm Eisenia fetida is a suitable species for vermicomposting and accumulation of heavy metals from biological wastes and soil. The significant heavy metal accumulation of Co, Cr and Pb were observed to decrease in final vermicompost of animal dung and in wheat grain. There was observed that the application of vermicompost and use of Eisenia fetida in wheat field soil which remediate the toxic heavy metal from wheat grains and beneficial for human, animal and environment. Maximum cobalt70.85%,Cromium 64.11% and lead 72.29% significant decrease was observed in buffalo dung in final vermicompost with respect to initial feed mixture. The accumulation of heavy metals from soil and wheat grains by earthworm protect the human health.
