Book Description
This book helps the readers get a holistic understanding of the emergence of biochar-nanocomposite research. The low and long-term exposure of persistent hazardous pollutants in environment is well known for damaging the water, soil, sediments, and living biota. Thus, it is a crucial step to eliminate these pollutants from environment regimes to prevent the on-site destruction or the transfer into the food chain. Biochar is a carbon-rich solid material generated through pyrolysis of biomass, and currently, it is covering the hotspot in environmental management of pollutants. It is being utilized for the efficient immobilization and sorption of organic pollutants, heavy metals, dyes, improvement of soil redox conditions, aggregate stabilization, photocatalytic degradation, and for carbon sequestration. The fascinating properties like surface area, porous structures, functional groups, and mineral components turn it into suitable candidate for the removal of various class of pollutants from environmental matrices. Different reactions like sorption, reduction, precipitation, solidification, and degradation are mainly responsible for the effective cleaning of xenobiotics from environment through biochar application. However, rapidly evolving contaminants in the environment have made the remediation more complex, expensive, and challenging. In view of these aspects, the modification of biochar through the doping of nanometals/metal oxides/surfactants/ or chemical entities will result in modified biochar with high surface area, more functional entities, improved physical, chemical, thermal, and mechanical characteristics with more adsorptive sites. Inclusion of these exclusive properties can be done through magnetic modification, impregnation of nanometals/ metal oxides/surfactants, amination, acid/base reactions, steam activation, etc. The resulted biochar-based nanocomposites have demonstrated a vital role in remediation of persistent organic pollutants, radionuclei, and heavy metals through the various interaction mechanisms like surface complexation, π–π interaction, electrostatic interaction, hydrogen bonding, Fenton process, and photocatalytic degradation. Currently, advanced research work has been carried out for the designing of modified composites of biochar to achieve maximum removal efficiency, reusability, biotoxicity, and sustainability. Hence, for selective removal of pollutants through designed biochar surface with the focused experimentation toward optimization of feedstocks, process variables, appropriate impregnation of nanomaterials, interaction with secondary pollutants, physical environment, longevity, and regeneration will definitely pave the way for safe and commercial application of biochar-based nanocomposites.

Book Description
Nanocomposites present outstanding mechanical properties and compatibility owing to their composite matrix and unique physical and chemical composition provided by large surface-area-to-volume ratios and high interfacial reactivity. Freedom to functionalize nanocomposites with various chemical groups increases their affinity toward target pollutants, which is highly desirable for the selective extraction of target analytes in complex environmental matrixes. This book presents the recent progress in the field of nanocomposites and their properties, fabrication methods, and applications for pollution control and sensing. It discusses the advances in pollution control techniques made possible because of nanocomposites and focuses on environment-friendly and efficient approaches. The text also covers economic, toxicological, and regulatory issues and research trends.

Book Description
Pollutants, Human Health and the Environment is a comprehensive, up-to-date overview of environmental pollutants that are of current concern to human health. Clearly structured throughout, the main body of the book is divided by pollutant type with a chapter devoted to each group of pollutants. Each chapter follows a similar format to facilitate comparison and discussion. For each pollutant, the authors describe the sources, pathways, environmental fate and sinks as well as known toxicological effects. Importantly, the second chapter on heavy metals and other inorganic substances deals with trace element deficiencies which can have serious problems for human health. Some rocks and soils are naturally low in some trace elements and intensive agriculture over the past half century has effectively mined many trace elements reducing their levels in soils and crops. The final chapter is a discussion about the various risk assessment frameworks and regulations covering the main pollutants. Comprehensive, up-to-date coverage of environmental pollutants of concern to human health Clearly divided into pollutant type with each chapter devoted to a different pollutant group Clearly structured throughout with the same format for each chapter to help facilitate comparison and discussion and enable readers to prioritise chemicals of concern Description of the sources, pathways, environmental fate and known toxicological effect Includes contributions from leading researchers and edited by a team of experts in the field
