Bioremediation of lead and nickel contaminated soil by Eudrilus eugeniae and the characterization of synthesized nanoparticles
Abstract
Bionanotechnology has emerged for developing a green and ecofriendly technology for recycling the non-destructive waste materials and cleaning the environment .the present study focuses on the bioremediation of heavy metal contaminated soil and safe disposal of heavy metals and minerals with the help of earthworms , namely Eudrilus eugeniae as an ecofriendly technique. The characterization studies were conducted on these heavy metal nanoparticle in soil by Dynamic Light Scattering to determine the particle size; Atomic Absorption Spectroscopy to analyze the free elements present and X-ray Diffraction study to determine the toxic chemical compounds and minerals present in the soil. Bioremediation of lead and nickel contaminated study using Eudrilus eugeniae was found very efficient. The study shows that the lead and nickel levels have reduced to the safety standard levels. Eudrilus eugeniae were able to accumulate lead and nickel contaminants in their tissue and reduce them to nano-sized particles.
