This book covers broader application of biotechnology for the protection of environment through different bioremediation and biodegradation techniques developed for removal of environmental contaminants including the recently discovered contaminants. The book offers a comprehensive overview of environmental pollutants including their fate, behavior, environmental and associated health risks. It is useful reading material for postgraduate and graduate students of environmental biotechnology, environmental microbiology and ecology. Young researchers also find the chapters useful understanding the latest developments.

This book provides a comprehensive overview of innovative remediation techniques and strategies for soils contaminated by heavy metals or organic compounds (e.g. petroleum hydrocarbons, NAPLs and chlorinated organic compounds). It discusses various novel chemical remediation approaches (in-situ and ex-situ) used alone and in combination with physical and/or thermal treatment. Further, it addresses the recovery of NAPLs, reuse of leaching solutions, and in-situ chemical reduction and oxidation, and explores the chemical enhancement of physical NAPLs recovery from both practical and theoretical perspectives. Also presenting the state-of-the-art in waste-assisted bioremediation to improve soil quality and the remediation of petroleum hydrocarbons, the book is a valuable resource for students, researchers and R&D professionals in industry engaged in the treatment of contaminated soils.
