Environmental threat due to toxic heavy metals is of prime concern worldwide. Rapid urbanization, industrialization and other developmental activities including anthropogenic activities (e.g. mining, fossil fuel burning) are the major contributors of heavy metals above the prescribed permissible limit. High concentration of heavy metals has detrimental impact on soil, water and air as well as human and animal health. Heavy metals exert toxic effects on soil microorganism hence results in the change of the diversity, population size and overall activity of the soil microbial communities. Heavy metal toxicity influences all soil microbial activity that involves change in the microbial population, diversity, their size and growth. Loss of soil fertility results in reduced crop yield and imbalance nutrition due to presence of excess amount of metals. Lead is non-biodegradable highly toxic heavy metal present in the …
