Heavy Metal Remediation: Sustainable Nexus Approach (Earth and Environmental Sciences Library)

by Nitish Kumar

Heavy metals, in general trace elements, are one of the major environmental problems. Nowadays, increasing environmental and global public health concerns related with environmental contamination by heavy metals are well known. Moreover, human exposure has risen dramatically because of an exponential increase of their use in several activities such as agricultural, industrial, technological and urban applications. They are presented in soils, water and atmosphere and they are a serious risk for the food chain.Approximately 10 million contaminated sites have been reported globally, occupying approximately 49.42 million acres of land, of which >50% is contaminated with toxic heavy metals. This situation warrants immediate attention to limit the introduction of heavy metals into soil systems and to remove the prevailing heavy metals from polluted soils. However, the majorities of existing heavy-metal-removal technologies are expensive, inefficient, or generate secondary pollutants. Therefore, it is of great importance to develop cheaper, environmentally friendly and sustainable approaches (including the development of new immobilizing agents) to manage and rehabilitate heavy-metal-contaminated soils. In the light of the aforementioned facts, this book sheds light on this global environmental issue, and proposes solutions to contamination through multi-disciplinary approaches and case studies from different parts of the world. It addresses sustainable heavy metal contamination remediation strategies using the potential applications of recent biological technology such as biotechnology, bioremediation, phytoremediation, biochar, absorbent, genetic engineering, and nanotechnology approaches. This book is of interest to researchers, teachers, environmental scientists, environmental engineers, environmentalists, and policy makers. Also, the book serves as additional reading material for undergraduate and graduate students of environmental microbiology, biotechnology, eco-toxicology, environmental remediation, waste management, and environmental sciences as well as the general audience.

Heavy Metal Toxicity: Human Health Impact and Mitigation Strategies (Environmental Science and Engineering)

by Nitish Kumar

This edited book brings together a diverse group of environmental science, sustainability, and health researchers to address the challenges posed by global mass poisoning caused by heavy metals contamination of soil and plants. In recent years, contamination of the environment by heavy metals has become a major concern. Their multiple industrial, domestic, agricultural, medical, and technological applications have led to their wide distribution in the environment, raising concerns over their potential effects on human health and the environment. Owing to their toxic, non-degradable, and bio-accumulative nature, the health burden on the population has increased significantly. Heavy metals such as arsenic, lead, mercury, cadmium, and uranium do not play a significant role in metabolism in the human body and are thus toxic. Their exposure in high concentration can cause acute toxicity resulting in acute health conditions, which is easy to observe and regulate, while similar is not visible for immediate action when their exposure is in trace amounts over the years. Heavy metals enter in the food chain through consumption of plant material. A high concentration of heavy metals has been found to be harmful to vegetation. As the heavy metals concentration in plants increases, it adversely affects several biological parameters and eventually renders the soil barren.The book sheds light on this global environmental issue and proposes solutions to contamination through multi-disciplinary approaches and case studies from different parts of the world. This book is a valuable resource to students, academicians, researchers, and environmental professionals who are doing field work on heavy metals contamination throughout the world.

Heavy Metals in the Marine Environment

by Robert W. Furness

The aim of this volume is to draw together state-of-the-art reviews of knowledge onlevels of heavy metals in marine environments (particularly in marine animals), the dynamicprocesses in these systems, toxic effects, and threats presented by heavy metals in foods ofmarine origin.All heavy metals, whether biologically essential or not, have the potential to be toxicto organisms at a threshold bioavailability. Such threshold concentrations vary betweenmetals, between species and with the physicochemical characteristics of the medium, somelike copper being particularly toxic even though essential in trace amounts. Responses ofanimals to metals in their medium or food depend to a large extent on the ability of speciesto regulate levels attained in their tissues. Higher animals have the capacity to regulate levelsof many metals, while marine invertebrates can regulate some within certain limits. Whereanimals cannot regulate physiological levels of metals, an alternative strategy is to detoxifyand store metals in relatively harmless forms. Knowledge of the manner in which animals deal with potentially toxic concentrations of heavy metals is of fundamental importance in the assessment of metal pollution by analysis of metal levels in biological samples. The interaction of heavy metals with biological materials is a key theme running through this volume. Toxic effects may be reflected at the individual, population, or ecosystem level, affecting species composition and production levels, or may be of direct dietary significance to man. The global cycling of metals through the marine environment is crucially affected by biological processes.

Hedgelands [US Edition]: A wild wander around Britain’s greatest habitat

by Christopher Hart

On this joyous journey around the wild edges of Britain, celebrated author Christopher Hart takes us through the life, ecology and history of the humble countryside hedge and how it is inextricably woven into our language, landscape and culture. Hedges – or hedgerows – have long been an integral part of the British landscape. An ancient, human-made boundary, hedgerows have become a critically important haven for wildlife and are now being recognised as one of the greatest ‘edge’ habitats on Earth. Britain boasts 400,000 kilometres of hedgerows, but has lost 50 per cent of them since the Second World War and their slow deterioration today is becoming a huge threat to the ecosystem. In Hedgelands, Christopher Hart shares the history of the hedge, highlighting the hawthorn and hazel of ancient hedgerows, and reveals its abundance of wildlife, from the elusive dunnock to the iconic nightingale, the industrious hedgehog to the miniscule harvest mouse. He demonstrates how this true environmental hero and powerful climate ally can help rebuild species-rich, resilient havens for birds, mammals and insects. Hedges play a vital role in mature woodland, grassland and even wetland, all of which can offer us much-needed ecological diversity and carbon sequestration. Through rewilding a patch of land in southwest England, Christopher shows us how easy, joyful and rewarding it is to restore even the smallest stretch of hedge. Whether you live in the country or the city, Hedgelands shares how simple actions can make a huge difference to the future of our precious hedges – and environment. “What’s good for us is good for nature, and what’s good for nature is good for us. And nowhere is this more true than in the bustling, flourishing, flowering, fruiting and altogether glorious native British hedge.”—Christopher Hart

Hedonizing Technologies: Paths to Pleasure in Hobbies and Leisure

by Rachel P. Maines

Rachel P. Maines’s latest work examines the rise of hobbies and leisure activities in Western culture from antiquity to the present day. As technologies are "hedonized," consumers find increasing pleasure in the hobbies’ associated tools, methods, and instructional literature.Work once essential to survival and comfort—gardening, hunting, cooking, needlework, home mechanics, and brewing—have gradually evolved into hobbies and recreational activities. As a result, the technologies associated with these pursuits have become less efficient but more appealing to the new class of leisure artisans. Maines interprets the growth and economic significance of hobbies in terms of broad consumer demand for the technologies associated with them. Hedonizing Technologies uses bibliometric and retail census data to show the growth in world markets for hobby craft tools, books, periodicals, and materials from the late 18th century to today. The book addresses basic issues in the history of labor and industry and makes an original contribution to the discussion of how technology and people interact.

Hedy's Folly: The Life and Breakthrough Inventions of Hedy Lamarr, the Most Beautiful Woman in the World

by Richard Rhodes

What do Hedy Lamarr, avant-garde composer George Antheil, and your cell phone have in common? The answer is spread-spectrum radio: a revolutionary inven­tion based on the rapid switching of communications sig­nals among a spread of different frequencies. Without this technology, we would not have the digital comforts that we take for granted today. Only a writer of Richard Rhodes's caliber could do justice to this remarkable story. Unhappily married to a Nazi arms dealer, Lamarr fled to America at the start of World War II; she brought with her not only her theatrical talent but also a gift for technical innovation. An introduction to Antheil at a Hollywood dinner table culminated in a U.S. patent for a jam- proof radio guidance system for torpedoes--the unlikely duo's gift to the U.S. war effort. What other book brings together 1920s Paris, player pianos, Nazi weaponry, and digital wireless into one satisfying whole? In its juxtaposition of Hollywood glamour with the reality of a brutal war, Hedy's Folly is a riveting book about unlikely amateur inventors collaborating to change the world.From the Hardcover edition.

Helicopter Flight Dynamics: Including a Treatment of Tiltrotor Aircraft (Aerospace Series)

by Gareth D. Padfield

The Book The behaviour of helicopters and tiltrotor aircraft is so complex that understanding the physical mechanisms at work in trim, stability and response, and thus the prediction of Flying Qualities, requires a framework of analytical and numerical modelling and simulation. Good Flying Qualities are vital for ensuring that mission performance is achievable with safety and, in the first and second editions of Helicopter Flight Dynamics, a comprehensive treatment of design criteria was presented, relating to both normal and degraded Flying Qualities. Fully embracing the consequences of Degraded Flying Qualities during the design phase will contribute positively to safety. In this third edition, two new Chapters are included. Chapter 9 takes the reader on a journey from the origins of the story of Flying Qualities, tracing key contributions to the developing maturity and to the current position. Chapter 10 provides a comprehensive treatment of the Flight Dynamics of tiltrotor aircraft; informed by research activities and the limited data on operational aircraft. Many of the unique behavioural characteristics of tiltrotors are revealed for the first time in this book. The accurate prediction and assessment of Flying Qualities draws on the modelling and simulation discipline on the one hand and testing practice on the other. Checking predictions in flight requires clearly defined mission tasks, derived from realistic performance requirements. High fidelity simulations also form the basis for the design of stability and control augmentation systems, essential for conferring Level 1 Flying Qualities. The integrated description of flight dynamic modelling, simulation and flying qualities of rotorcraft forms the subject of this book, which will be of interest to engineers practising and honing their skills in research laboratories, academia and manufacturing industries, test pilots and flight test engineers, and as a reference for graduate and postgraduate students in aerospace engineering.

Helicopter Theory

by Wayne Johnson

The history of the helicopter may be traced back to the Chinese flying top (c. 400 BC) and to the work of Leonardo da Vinci, who sketched designs for a vertical flight machine utilizing a screw-type propeller. In the late 19th-century, Thomas Edison experimented with helicopter models, realizing that no such machine would be able to fly until the development of a sufficiently lightweight engine. When the internal combustion gasoline engine came on the scene around 1900, the stage was set for the real development of helicopter technology.While this text provides a concise history of helicopter development, its true purpose is to provide the engineering analysis required to design a highly successful rotorcraft. Toward that end the book offers thorough, comprehensive coverage of the theory of helicopter flight: the elements of vertical flight, forward flight, performance, design, mathematics of rotating systems, rotary wing dynamics and aerodynamics, aeroelasticity, stability and control, stall, noise and more.Wayne Johnson has worked for the U.S. Army and NASA at the Ames Research Center in California. Through his company Johnson Aeronautics, he is engaged in the development of software that is used throughout the world for the analysis of rotorcraft. In this book, Dr. Johnson has compiled a monumental resource that is essential reading for any student or aeronautical engineer interested in the design and development of vertical-flight aircraft.
