This book presents recent developments involving the role of nanoparticles on plant physiology and growth. Nanotechnology applications include improvement of agricultural production using bio-conjugated NPs (encapsulation), transfer of DNA in plants for development of insect pest-resistant varieties, nanoformulations of agrochemicals such as pesticides and fertilizers for crop improvement, and nanosensors/nanobiosensors in crop protection for identification of diseases and residues of agrochemicals. Recent findings on the increased use of nanotechnology in agriculture by densely populated countries such as China and India indicate that this technology may impart a substantial impact on reducing hunger, malnutrition, and child mortality.

This book focuses on successful application of microbial biotechnology in areas such as medicine, agriculture, environment and human health.

Waste Management Practices: Municipal, Hazardous, and Industrial, Second Edition addresses the three main categories of wastes (hazardous, municipal, and "special" wastes) covered under federal regulation outlined in the Resource Conservation and Recovery Act (RCRA), an established framework for managing the generation, transportation, treatment, storage, and disposal of several forms of waste. Focusing on integrating the technical and regulatory complexities of waste management, this book covers the historical and regulatory development of waste management and the management of municipal solid wastes. It also addresses hazardous wastes and their management, from the perspectives of identification, transportation, and requirements for generators as well as the treatment, storage, and disposal facilities. Features: Covers the three main categories of wastes under regulation in the United States Incorporates an extensive set of problems, presented at the end of several chapters as appendices Includes numerous review/homework questions at the end of each chapter Highlights special categories of waste that may not fit precisely into either RCRA Subtitle D (Solid Wastes) or Subtitle C (Hazardous Wastes) In addition to the end-of-chapter problems provided in all chapters of this book, the text also contains practical exercises using data from field situations. Waste Management Practices: Municipal, Hazardous, and Industrial, Second Edition is an ideal textbook or reference guide for students and professionals involved in the management of all three categories of wastes.

This introductory manual addresses environmental site restoration practices that both ensure compliance with federal statutes and prevent further contamination or expense. It also includes up-to-date information and several new features to enhance the process. Emphasizing environmental chemistry, soil science, microbiology, plant science, and the underlying chemical processes, author John Pichtel discusses relevant chemical principles as they apply to the cleanup and removal of hazardous chemicals from soil, geological strata, and groundwater. The first part of this book provides an overview of the recent history of environmental contamination and the formulation of relevant regulations, leading to regulations for hazardous waste site remediation. This part also provides a background for several salient aspects of site remediation. The second part of the book closely examines field remediation technologies, including phytoremediation, bioremediation, and electrokinetic remediation. Theory of operation, practical considerations, and possible environmental impacts and other consequences of use are also discussed. Readers of the first edition will discover two new chapters in this Second Edition covering permeable reactive walls and technology selection. This updated edition now also includes end-of-chapter questions and instructions for completing two web-based exercises, one for the chapter on environmental site assessments and one for the chapter on technology selection.

This new edition discusses chemical and engineering principles as they apply to the cleanup and removal of hazardous chemicals from soil and groundwater. There is emphasis on environmental chemistry, soil science, microbiology, and plant science. The first part of the book provides an overview of the recent history of environmental contamination and the formulation of relevant regulations for hazardous waste site remediation. This part also provides a background for several salient aspects of site remediation (e.g., soil science, the site assessment process). The second part of the book examines field remediation technologies, including phytoremediation, bioremediation, and several chemical and physical technologies. Theory of operation, practical considerations, and possible environmental impacts and other consequences of their use are discussed. *Covers both metal- and hydrocarbon-based contamination and remediation *Many competitors only address one industry, or source, of contamination-this title provides an overview of all of the sources. *Presents both the assessment of contaminated sites and the technologies currently available for environmental cleanup *Effective for use in field situations and for academic (i.e., university course) use. *Two new chapters: (i) the use of nanomaterials for remediation of contaminated soil and water; and (ii) revegetation of severely disturbed sites.

An in-depth look at what microplastics are, how prevalent they are, and what can be done about them for a professional and academic audience. The first part of the book provides an overview of plastics types, how they are released to the environment, and how they interact with organisms. This part also provides a background for several salient aspects of microplastics hazards (e.g., attachment of toxic chemicals, toxicity to organisms). Special attention will be paid to how microplastics decompose in the environment (which is significant in terms of mobility of toxicity). Subsequent chapters address how to sample and identify microplastics. The second part of the book examines technologies for removal of microplastics from water, wastewater and from soil. Biological, chemical and physical technologies are presented. Theory of operation, practical considerations, and possible environmental impacts of their use are discussed. Key aspects include: * technologies available for removal of microplastics from wastewater and surface water; * how various toxins which are sorbed to microplastics adversely affect wastewater treatment processes; * technologies at the pilot- and field stage for removal of microplastics from sediment; * industrial practices for preventing microplastic losses from manufacturing facilities; and * the distribution of microplastics in the atmosphere. Written by John Pichtel, author of the acclaimed Fundamentals of Site Remediation, and Mathew Simpson.
