In its present condition, the dam of the tailings pond is less stable than is recommended by international practice. A surveillance system has been established to observe both vertical and horizontal soil movement and the buildup of stresses in the soil. The stability of the dam depends primarily on erosion by shore processes and the consequent reduction of the counterbalance, as well as the reduction in strength of the Cambrian clay underlying the dam caused by creep and by water percolating to the bottom of the pond. The most critical need is to enlarge the counterbalance and to stop erosion. The surveillance system should be supplemented with a system of inclinometers. Monitoring of coastal processes should be continued. At present, the hydrodynamic stress on the dam is minimal because the pebble layer allows drainage of water out of the tailings pond and into the sea. The regulatory requirement to end emissions into the Baltic Sea must be met without causing undesirable hydrodynamic stresses on the dam. This could be done by covering the pond and diverting precipitation water. 9. References I. Report on Topographic-Geodetic Studies at the Tailings Pond. 1965, No. A-4-01187 (in Russian). 2.

Liberal use of figures and tables allows readers to visualize complex scientific phenomena and to understand their effects on every aspect of the environment from cells to entire ecosystems. Authored by two of the foremost educators, investigators, and practitioners in this increasingly important discipline, the new edition of Environmental Health Science is an essential resource for students and practitioners in public health; civil, environmental, and chemical engineers; policy makers; science journalists; and anyone else committed to promoting human health and the health of our environment.
Environmental remediation technologies to control or prevent pollution from hazardous waste material is a growing research area in academia and industry, and is a matter of utmost concern to public health, to improve ecology and to facilitate the redevelopment of a contaminated site. Recently, in situ and ex situ remediation technologies have been developed to rectify the contaminated sites, utilizing various tools and devices through physical, chemical, biological, electrical, and thermal processes to restrain, remove, extract, and immobilize mechanisms to minimize the contamination effects. This handbook brings altogether classical and emerging techniques for hazardous wastes, municipal solid wastes and contaminated water sites, combining chemical, biological and engineering control methods to provide a one-stop reference. This handbook presents a comprehensive and thorough description of several remediation techniques for contaminated sites resulting from both natural processes and anthropogenic activities. Providing critical insights into a range of treatments from chemical oxidation, thermal treatment, air sparging, electrokinetic remediation, stabilization/solidification, permeable reactive barriers, thermal desorption and incineration, phytoremediation, biostimulation and bioaugmentation, bioventing and biosparging through ultrasound-assisted remediation methods, electrochemical remediation methods, and nanoremediation, this handbook provides the reader an inclusive and detailed overview and then discusses future research directions. Closing chapters on green sustainable remediation, economics, health and safety issues, and environmental regulations around site remediation will make this a must-have handbook for those working in the field.
Whether considered a threat to the health of humans in particular or of the ecosystem in general, the problem of air pollution affects us all. In addition to the 189 chemicals listed in the air toxins category of the 1990 Clean Air Act Amendments, smog, acid rain, ozone depletion, and global warming all arise from air pollution. You can debate the prime causes óacid rain, excessive lumbering or changes in the weather ó but the diminishing rainforest and the spreading desert speak for themselves.

Vor 10000 Jahren, zu Beginn des Neolithikums begann der Mensch sesshaft zu werden. Er leitete damit einen neuen Prozess in das erdge- schichtliche Geschehen ein, namlich Wachstum und Expansion der eigenen Spezies uber die naturgegebene Umweltkapazitat hinaus. Er- kauft wird diese Entwicklung mit der starken Inanspruchnahme der endlichen Ressourcen Materialien und Raum sowie der Belastung von Natur und Umwelt auf eine unseren Planeten nachhaltig bedrohende Art und Weise. Bis zur agrarischen Revolution in der Jungsteinzeit war der Mensch als Jager und Sammler Teil naturlicher OEkosysteme und da- mit vergleichbar den tierischen Organismen den naturgegebenen Ge- setzmassigkeiten unterworfen. Dann rodete er den Wald, bearbeitete den Boden, kultivierte ausgewahlte Pflanzen, entwickelte die Haustier- haltung und schuf mit festem Wohnsitz in seinen doerflichen Sied- lungsgemeinschaften die Voraussetzung fur eine systematische Vor- ratshaltung. Die Tragfahigkeit eines Gebietes war jetzt nicht mehr aus- schliesslich durch die in Raum und Zeit begrenzten Naturressourcen bestimmt. Der Mensch hatte einen Weg gefunden, sie durch zielge- richtete Massnahmen systematisch zu erweitern. Mit dieser Befreiung aus der strengen Abhangigkeit von der Natur scherte der Mensch aus den regelnden Zwangen der Evolution aus und begann, sich uber die populationserhaltende Reproduktion hinaus nachhaltig zu vermehren. Seit 1850 hat sich die Weltbevoelkerung verfunffacht auf 6 Mrd. ge- gen Ende des 20. Jahrhunderts. Gleichzeitig wuchs der Verbrauch an Primarenergie, gegenwartig zu 75% durch fossile Energietrager ge- deckt, um mehr als das Dreissigfache. Spatestens jetzt wurde das be- sonders verschwenderische Verhalten des Menschen offenbar.

This new edition of a bestselling textbook continues to emphasize principles rather than practice, providing the interdisciplinary perspective and grounding required for research.
Every person on our home planet is affected by a worldwide deluge of man-made chemicals and pollutants - most of which have never been tested for safety. Our chemical emissions are six times larger than our total greenhouse gas emissions. They are in our food, our water, the air we breathe, our homes and workplaces, the things we use each day. This universal poisoning affects our minds, our bodies, our genes, our grandkids, and all life on Earth. Julian Cribb describes the full scale of the chemical catastrophe we have unleashed. He proposes a new Human Right - not to be poisoned. He maps an empowering and hopeful way forward: to rid our planet of these toxins and return Earth to the clean, healthy condition which our forebears enjoyed, and our grandchildren should too.

"Trash is a bit like birds. Both have their favourite habitats. I thought it might be worth taking a closer look at what we throw away and what it says about us. To follow the journey of the items we buy and discard. I wanted to find out more about what they're made of and what fate the future has in store for them." It starts with a day at the beach. A single white sock in the sand that somehow seems to spoil everything. It's enough to send Polish reporter and ornithologist Stanislaw Lubienski on a quest to understand what we throw away, where it goes and whether it will be our lasting legacy. By analysing items he unearths on his trips into nature - a plastic bottle, a tube of Russian penis-enlargement cream, a cigarette butt, an empty aerosol can - tracing their origins, their destination and the harm they can do, he shows how our consumer society has developed out of our control, to the point of environmental catastrophe. He also looks with a birdwatcher's eye at how various animals have come to adapt to and even rely on the rubbish we pollute their environment with, and at the cultural significance of trash and rubbish and the origins of our throw-away society. And in the finest Gonzo traditions, he inserts himself into his narrative by exmaning his own "environmental neurosis" and by going out with refuse crews to watch them work. Translated from the Polish by Zosia Krasodomska-Jones
Die Reduktion von Treibhausgasemissionen ist ein zentraler Bestandteil der Umweltpolitik. Die dominierenden Emissionen sind in Deutschland mit der Nutzung von Energie verbunden. Zur Unterst tzung von Politik, Wirtschaft, Wissenschaft und anderen interessierten Gruppierungen bei der Erarbeitung m glichst rationeller Emissionsminderungsstrategien haben acht f hrende wissenschaftliche Institutionen im IKARUS-Projekt energiewirtschaftliche Modelle und eine umfassende Technik- und Rahmendatenbank entwickelt. Deren Inhalte, Potential, aber auch Grenzen werden hier beschrieben und anhand von Beispielen verdeutlicht.
Particle samplers are widely used in workplaces in order to determine the concentration of airborne particles in the atmosphere. They generally operate by drawing air, with the aid of a pump, through one or more orifices in the sampler body and housed within the sampler is a filter through which the air is subsequently drawn. The airborne particles are collected on the filter and their concentration is determined. Various samplers have been designed for this purpose including "static" samplers, which are located in a fixed position in a working environment and determine the dust concentration averaged over a prescribed period of time at that one point, and "personal" samplers which are mounted on a working person near to the breathing zone. The ORB sampler, a static sampler designed by Ogden and Birkett (1978) to have approximately the same entry efficiency, for particles with aerodynamical diameter up to at least 25 m, as a human head equally exposed to all wind directions for wind speeds between 0 and 2. 75m1s, is shown in Fig. l. l and examples of personal samplers are shown in Fig. 1. 2a, b and c and represent a single 4mm hole sampler, a seven hole sampler and a 25mm open face filter holder respectively. These three samplers are some of the most commonly used personal samplers for sampling the total airborne concentrations of workplace dusts in Britain.
Enough plastic is thrown away every year to circle the world 4 times More than 8 million tonnes of plastic enter the oceans each year 300 million tonnes of new plastic is produced every year An estimated 15-51 trillion pieces of plastic now litter the world's oceans 38.5 million plastic bottles are used every day in the UK A million plastic bottles are used per minute around the world 500 million plastic straws are used per year Without big action, at the current rate, pieces of plastic will outnumber fish in the ocean by 2050. That is the legacy we are leaving our children and grandchildren. Plastic flows into our lives from every direction and most of it is not recycled. Instead it is incinerated or ends up in landfill, where it will sit for hundreds of years, or enters the world's seas where it fragments into tiny pieces to become microplastics - the environmental scourge of our times. Many of us had assumed that governments, brands and waste authorities were dealing with plastic on our behalf. But the impact of shows such as Blue Planet along with national beach cleans and high-profile campaigns have resulted in a collective wake-up call. If there were plans and strategies, they have not worked as we imagined. It would be easy to feel despondent but instead we need to turn our anger and emotion into action, starting by making a big dent in our own enormous consumption. Turning the tide on Plastic is here just in time. Journalist, broadcaster and eco lifestyle expert Lucy Siegle provides a powerful call to arms to end the plastic pandemic along with the tools we need to make decisive change. It is a clear-eyed, authoritative and accessible guide to help us to take decisive and effective personal action. Because this matters. When it comes to single-use plastics, we are habitual users, reaching out for plastic water bottles, disposable coffee cups, plastic straws and carrier bags multiple times a day. If only 12 of us adopt Lucy's 'reduce, rethink, refill, refuse' approach, we could potentially ditch 3K-15K single items of plastic in a year. When we consider our power as influencers - whether at school, the hairdressers, at work or on the bus - we suddenly become part of something significant. So now is the time to speak up, take action and demand the change you want to see in the ocean, in the supermarket aisles and on the streets. It's time to turn the tide on plastic, and this book will show you how.
Bringing together the research of 62 distinguished scientists in one volume, Environmental Contamination: Health Risks and Ecological Restoration offers a comprehensive view of the remediation of contaminated land. A one-stop resource, it covers historical and emerging contaminants, the issues of bioavailability of chemicals and their associated human health risks, and the latest remediation technologies. The book also contains numerous case studies, many of them drawn from the Asia-Pacific region, that look at the effects of rapid industrialization. The chapters are inspired by presentations and discussions held during the 2010 Croucher Advanced Study Institute workshop, entitled Remediation of Contaminated Land-Bioavailability and Health Risk. With the speed and scale of recent socioeconomic development, particularly in regions with less stringent environmental regulations, it is evident that various industrial activities have given rise to tremendous environmental degradation and severe health problems. The book begins with a description of current problems and future trends of pollutants, as well as their impact on the environment and human health. It then focuses on emerging contaminants, such as flame retardants and electronic waste. The book also examines research on environmentally friendly and sustainable solutions to remediate contaminated lands, exploring cutting-edge bioremediation and phytoremediation technologies. Chapters discuss arsenic biomethylation, copper homeostasis, microbial transformation of phthalate esters, the potential function of paddy fields in phytoremediation, the use of constructed wetlands for pollution control, phytostabilization of arsenic-contaminated sites, and more. This timely book provides readers with a highly focused reference on some of the most urgent environmental and health issues and research topics. These include e-waste recycling and arsenic and heavy met
This book describes the environmental problems associated with agriculture, particularly the use of pesticides and chemical fertilizers and the disposal of animal waste. These have become major policy issues in many countries, with the main polluting effect being on water quality. As with other types of pollution, significant reductions in agriculture's contribution to water pollution requires the application of either enforceable regulatory approaches or changes in the economic environment, so that farmers adopt environmentally-friendly production practices. Providing a review and guide to the policy options and their economic administrative and political merits, the reader can develop an understanding of these options and their merits in the emerging policy context. The principal focus is on the developed world, particularly North America and Europe. The book is aimed at advanced students, researchers and professionals in agricultural economics and policy, and environmental and pollution sciences.
Initially marketed as a life-saving advancement, flame retardants are now mired in controversy. Some argue that data show the chemicals are unsafe while others continue to support their use. The tactics of each side have far-reaching consequences for how we interpret new scientific discoveries. An experienced environmental sociologist, Alissa Cordner conducts more than a hundred interviews with activists, scientists, regulators, and industry professionals to isolate the social, scientific, economic, and political forces influencing environmental health policy today. Introducing "strategic science translation," she describes how stakeholders use scientific evidence to support nonscientific goals and construct "conceptual risk formulas" to shape risk assessment and the interpretation of empirical evidence. A revelatory text for public-health advocates, Toxic Safety demonstrates that while all parties interested in health issues use science to support their claims, they do not compete on a level playing field and even good intentions can have deleterious effects. |
