Abstract

This research investigated the ability of compost in which microbes augmented lead removal from soil. Various levels of lead polluted soil, ranging from 10 to 70 mg-Pb/Kg-soil were amended with compost. Microbial species in compost and polluted soil were identified. Criteria for effective removal of lead were half time for 50% lead removal and 50% microbial elimination (t-50). Initial concentration of lead in soil for the half time, the so called initial concentration time fifty (ICT-50) was a novel criterion to assess the maximum lead concentration initially present in soil. ICT-50 of 35 mg-Pb/Kg-soil could be treated by compost addition of more than the weight of polluted soil.
