This book explains the holistic knowledge of xenobiotics and their mode of action, as well as their toxic impact on living organisms at the cellular level. It also enlightens readers about various mitigation approaches against xenobiotics, especially phytoremediation-based technology. In addition, this book provides a critical overview of xenobiotic contamination in both abiotic and biotic components of the environment. Recent trends in various molecular remedial strategies, such as nanotechnology and microbe-assisted approaches, have also been discussed. Omics approaches in xenobiotics are also discussed. Key features discussed in this book include:Biomonitoring of xenobiotics, deteriorating quality of aquatic bodies due to xenobiotics, and current approaches for remediation of xenobiotics. Moreover, transgenic approaches for combating xenobiotic toxicity are also one of the landmarksA burning issue over persistent organic pollutants (POPs), sources of POPs and their contamination in food products, types of persistent organic pollutants, and impact of persistent organic pollutants on the Arctic region are among the major key featuresThe latest mitigation technology, including the role of nanotechnology, is very interesting. Another important feature of this book is the inclusion of defense system mechanisms of tolerant plants to combat xenobiotics and biotransformation of xenobioticsGenetic alteration in living organisms to combat toxicity exerted by xenobiotics has also been highlightedThis book is a timely addition to the field and will act as a landmark. This book is ideal for those who are looking to deepen their knowledge about the xenobiotics spectrum in the environment, their augmentation, and green technology to combat it. This book is suitable for students, researchers, academicians, and policy makers.
