Environmental contaminants are chemicals that accidentally or deliberately enter the environment, often, but not always, as a result of human activities. Some of these contaminants may have been manufactured for industrial use, and because they are very stable, they do not break down easily. If released to the environment, these contaminants may enter the food chain. Other environmental contaminants are naturally occurring chemicals, but industrial activity may increase their mobility or increase the amount available to circulate in the environment, allowing them to enter the food chain at higher levels than would otherwise occur. Environmental contaminants influence the physiological cell reactions at different and heterogeneous basics and lead to altering in normal cell function primarily at the molecular and biochemical level. Molecular responses to such common environmental stresses have been studied intensively over the last few years, in which there is an intricate network of signaling pathways controlling perception of these environmental stress signals, the generation of second messengers and signal transduction. Recent advances in many areas of plant and microbial research, including genotyping, make scientists optimistic that valuable solutions will be found to allow deployment/commercialization of strategies better able to tolerate these environmental stresses.

Environmental remediation was historically viewed as an inherently sustainable activity, as it restores contamination; however, researchers and practitioners are increasingly recognizing that there can be substantial environmental footprints and socioeconomic costs associated with remediation. Sustainability is an imperative in the emerging green and sustainable remediation movement, which is reshaping the entire remediation industry.

Understanding the significant roles of sustainable or eco-friendly approaches in mitigating environmental contaminants, the current subject has recently attracted the attention of scientists from across the globe. This comprehensive volume ¿Sustainable Management of Environmental Contaminants: Eco-friendly Remediation Approaches" highlights the various prospects involved in current scenario. The current volume comprises the chapters from diverse areas dealing with biotechnology, microbial technology, nanotechnology, molecular biology, green and sustainable remediation, etc. I am hopeful that this volume will furnish the requisite of all those who are working or have interest in the current topic.
