Interaction And Fate Of Pharmaceuticals In Soil Crop Systems

This book provides a comprehensive overview of the current knowledge on the fate and interaction of pharmaceuticals in soil-crop systems. It addresses the principles of their transport, uptake and metabolism and reviews methodologies for their analytical determination. It also discusses ecotoxicological effects arising from their presence and highlights bioremediation approaches for their removal. The use of treated wastewater to irrigate crops is becoming more widespread in regions where freshwater is limited. This practice conserves freshwater resources and contributes to nutrient recycling. However, concerns remain regarding the safety of irrigation with treated wastewater since it contains residues of pharmaceuticals that have survived treatment, which means that soil and fauna are potentially exposed to these xenobiotics. Various pathways govern the fate of pharmaceuticals in crop-soil systems, including soil degradation; formation of non-extractable residues; uptake by soil-dwelling organisms (e.g. earthworms); and uptake, transport, and metabolism in agricultural crops. Investigations into these aspects have only recently been initiated, and there is still a long way to go before a meaningful assessment of the impact of wastewater has been completed.

This book covers the various aspects of MXenes nanomaterials and its composites from the fabrication to the potential applications in energy devices, sensors, and environmental remediation. MXenes are two-dimensional (2D) transition metal carbides and nitrides which contains novel combination of properties including great conductivity and mechanical, thermal features of transition metal carbide and nitrides. In addition, MXenes nanomaterials possess high surface area, novel morphology, and layered structure and the functionalized of its surfaces gives it excellent hydrophilic characteristics and high absorption of electromagnetic radiations making them versatile materials for various applications. The beginning part of the book gives an in-depth literature covering the fundamental principles, fabrication, self-assembling strategies of nano-engineered MXenes, and their composites materials. The later chapters describe the chemical functionalization of MXenes nanomaterials for diversified applications such as electromagnetic shielding, energy storage devices (super capacitors, lithium ion batteries, CO2 capture, optical switching, transistors), photo catalysis, drug delivery, implants, tissue engineering, water purification, and sensing applications. It demonstrates that MXene-based advanced architectures promote continuous innovations and provide driving force in different fields particularly in environmental remediation and energy storage devices. This book is essential reading for all chemists, biologists, physicists, and environmental scientists working in the field of nanotechnology, energy, and environmental chemistry. It helps academics and professionals to polish their knowledge with the latest described data. It also helps professionals in developing innovative technologies by keeping in mind the applications of functionalized nanostructured MXenes.

This book covers topics that addresses the global environmental issues, their challenges, and mitigation strategies for sustainable development. Some of the major challenges global environment is facing currently are global warming induced climate change because of which various extreme weather events such as flood, drought, cyclone, forest fires have increased. Industrialization with urbanization and human anthropogenic activities have caused detrimental effect on the environment resulting in environmental pollution (air and water pollution), deforestation, degradation of ecosystems, soil erosion, ground water depletion, drinking water scarcity, biodiversity loss, depletion of fossil fuels, etc. Therefore, it has become utmost necessary to switch to significant lifestyle stages along with conservation of natural resources for a sustainable environment. Sustainable environment may be defined as the practice of responsibly managing natural resources and protect overall ecosystem to support health and well-being of present and future generations. One of the major environment sustainability is the use of renewable sources of energy such as solar, wind, hydroelectric, and biomass which will reduce environmental pollution and also minimize resource misuse. At the same time, crop rotation, solid waste management, water treatment, wastewater treatment are some of the sustainable practices we must carry out for a sustainable environment. Hope, the content of the book gives an overview of recent developments, knowledge gaps related to new research areas related to environment and their future prospects.

Ecological Significance of Riparian Ecosystems: Challenges and Management Strategies examines the current issues related to river ecosystems, their environmental importance, pollution issues and potential management strategies. The book is divided into 4 key themes: Basics of river ecosystem, Natural phenomenon of river ecosystem, Human-induced problems of river ecosystem, and Management measures for the river ecosystem. Through these four themes, the contributors present both practical and theoretical aspects of river ecosystem in changing climate. An emphasis has been made on the recent research of climate change and its impact on the river ecosystem. River ecosystems have tremendous potential to store CO2, however, with changing climatic and anthropogenic activities, these habitats are under threat, and river ecosystems are losing the very vital service of storing carbon. Unlike well documented terrestrial biodiversity, the biodiversity in aquatic ecosystems is still unrecognized to some extent. Presents an understanding of the biogeochemical processes of river ecosystems achieved by food webs and diverse biogeochemical processes Covers sediment dynamics and nutrient chemistry - hot topics in river ecosystems Includes environmental pollution issues in river ecosystems from various anthropogenic activities

This document presents key messages and the state-of-the-art of soil pollution, its implications on food safety and human health. It aims to set the basis for further discussion during the forthcoming Global Symposium on Soil Pollution (GSOP18), to be held at FAO HQ from May 2nd to 4th 2018. The publication has been reviewed by the Intergovernmental Technical Panel on Soil (ITPS) and contributing authors. It addresses scientific evidences on soil pollution and highlights the need to assess the extent of soil pollution globally in order to achieve food safety and sustainable development. This is linked to FAO’s strategic objectives, especially SO1, SO2, SO4 and SO5 because of the crucial role of soils to ensure effective nutrient cycling to produce nutritious and safe food, reduce atmospheric CO2 and N2O concentrations and thus mitigate climate change, develop sustainable soil management practices that enhance agricultural resilience to extreme climate events by reducing soil degradation processes. This document will be a reference material for those interested in learning more about sources and effects of soil pollution.
