Book Description
Understand the fundamentals of human risk assessment with this introduction and reference Human risk assessments are a precondition for virtually all industrial action or environmental regulation, all the more essential in a world where chemical and environmental hazards are becoming more abundant. These documents catalog potential environmental, toxicological, ecological, or other harms resulting from a particular hazard, from chemical spills to construction projects to dangerous workplaces. They turn on a number of variables, of which the most significant is the degree of human exposure to the hazardous agent or process. Human and Ecological Risk Assessment combines the virtues of a textbook and reference work to introduce and analyze these vital documents. Beginning with the foundational theory of human health risk assessment, it then supplies case studies and detailed analysis illustrating the practice of producing risk assessment documents. Fully updated and authored by leading authorities in the field, the result is an indispensable work. Readers of the second edition of Human and Ecological Risk Assessment will also find: Over 40 entirely new case studies reflecting the latest in risk assessment practice Detailed discussion of hazards including air emissions, contaminated food and soil, hazardous waste sites, and many more Case studies from multiple countries to reflect diverse international standards Human and Ecological Risk Assessment is ideal for professionals and advanced graduate students in toxicology, industrial hygiene, occupational medicine, environmental science, and all related subjects.

Book Description
Nanotechnologies in Food provides an overview of the products and applications of nanotechnologies in agri-food and related sectors. Following on from the success of the first edition, this new edition has been revised and updated to bring the reader fully up to date on the emerging technological, societal, and policy and regulatory aspects in relation to nanotechnologies in food. This book contains new chapters discussing some of the aspects that have attracted a lot of debate and research in recent years, such as how the regulatory definition of ‘nanomaterial’ is shaping up in Europe and whether it will result in a number of exciting food additives being regarded as nanomaterials, how the new analytical challenges posed by manufactured nanoparticles in food are being addressed and whether the emerging field of nano delivery systems for food ingredients and supplements, made of food materials or other soft/degradable polymers, can raise any consumer safety concerns. The edition concludes by discussing the future trends of the technological developments in the area of nanotechnologies and potential future ‘fusion’ with other fields, such as biotechnology and synthetic biology. This book provides a source of much needed and up-to-date information on the products and applications of nanotechnology for the food sector - for scientists, regulators, and consumers alike. It also gives an independent, balanced, and impartial view of the potential benefits as well as risks that nanotechnology applications may bring to the food sector. Whilst providing an overview of the state-of-the-art and foreseeable applications to highlight opportunities for innovation, the book also discusses areas of uncertainty in relation to public perception of the new technological developments, and potential implications for consumer safety and current regulatory controls. The book also discusses the likely public perceptions of nanotechnologies in the light of past technological developments in the food sector, and how the new technology will possibly be regulated under the existing regulatory frameworks.

Book Description
"Biochar is the carbon-rich product when biomass (such as wood, manure, or crop residues) is heated in a closed container with little or no available air. It can be used to improve agriculture and the environment in several ways, and its stability in soil and superior nutrient-retention properties make it an ideal soil amendment to increase crop yields. In addition to this, biochar sequestration, in combination with sustainable biomass production, can be carbon-negative and therefore used to actively remove carbon dioxide from the atmosphere, with major implications for mitigation of climate change. Biochar production can also be combined with bioenergy production through the use of the gases that are given off in the pyrolysis process.This book is the first to synthesize the expanding research literature on this topic. The book's interdisciplinary approach, which covers engineering, environmental sciences, agricultural sciences, economics and policy, is a vital tool at this stage of biochar technology development. This comprehensive overview of current knowledge will be of interest to advanced students, researchers and professionals in a wide range of disciplines"--Provided by publisher.

Book Description
Hazardous pollutants are a growing concern in treatment engineering. In the past, biological treatment was mainly used for the removal of bulk organic matter and the nutrients nitrogen and phosphorous. However, relatively recently the issue of hazardous pollutants, which are present at very low concentrations in wastewaters and waters but are very harmful to both ecosystems and humans, is becoming increasingly important. Today, treatment of hazardous pollutants in the water environment becomes a challenge as the water quality standards become stricter. Hazardous Pollutants in Biological Treatment Systems focuses entirely on hazardous pollutants in biological treatment and gives an elaborate insight into their fate and effects during biological treatment of wastewater and water. Currently, in commercial and industrial products and processes, thousands of chemicals are used that reach water. Many of those chemicals are carcinogens, mutagens, endocrine disruptors and toxicants. Therefore, water containing hazardous pollutants should be treated before discharged to the environment or consumed by humans. This book first addresses the characteristics, occurrence and origin of hazardous organic and inorganic pollutants. Then, it concentrates on the fate and effects of these pollutants in biological wastewater and drinking water treatment units. It also provides details about analysis of hazardous pollutants, experimental methodologies, computational tools used to assist experiments, evaluation of experimental data and examination of microbial ecology by molecular microbiology and genetic tools. Hazardous Pollutants in Biological Treatment Systems is an essential resource to the researcher or the practitioner who is already involved with hazardous pollutants and biological processes or intending to do so. The text will also be useful for professionals working in the field of water and wastewater treatment.

Book Description
This is the 2nd edition of the original “Nanostructures and Nanomaterials” written by Guozhong Cao and published by Imperial College Press in 2004.This important book focuses not only on the synthesis and fabrication of nanostructures and nanomaterials, but also includes properties and applications of nanostructures and nanomaterials, particularly inorganic nanomaterials. It provides balanced and comprehensive coverage of the fundamentals and processing techniques with regard to synthesis, characterization, properties, and applications of nanostructures and nanomaterials. Both chemical processing and lithographic techniques are presented in a systematic and coherent manner for the synthesis and fabrication of 0-D, 1-D, and 2-D nanostructures, as well as special nanomaterials such as carbon nanotubes and ordered mesoporous oxides. The book will serve as a general introduction to nanomaterials and nanotechnology for teaching and self-study purposes.
