Prozesse der industriellen Produktion und der Energieumwandlung basieren auf linearen Stoffstromen, d. h. Rohstoffe werden aus der N atur entnommen, zu Wertstoffen und Reststoffen/ AbfaIlen transformiert und anschlieBend in die Natur zuriickgeflihrt. Vor allem in den letzten 10 Jahren hat der Wissenszu wachs iiber derartige Immissionen und ihre Wirkungen in Boden und Wasser jedoch verdeutlicht, daB die Erde nur ein begrenztes Aufnahme- und Abbaupo tentia fUr Reststoffe/ AbfaIle hat. Zur LOsung dieses Problems wurde dabei lange iibersehen, daB die N atur selbst die besten Beispiele vorgibt. Dazu geho ren u. a. Stoftkreislaufe mit geochemischen Prozessen der Stoffumwandlung und -differenzierung wie z. B. der Kohlendioxid-, Stickstoff- oder Schwefel kreislauf. Die Ubertragung des Prinzips geschlossener Materialstrome auf Reststoffe/ Ab faIle, umschreibbar mit den bekannten Worten Recycling und Verwertung, ist jedoch nicht ohne weiteres moglich. Notwendige Konzepte und fortschrittliche Techniken miissen in den meisten Hillen erst noch entwickelt werden. Dariiber hinaus sind auch wirtschaftliche und politische Schwierigkeiten beachtlich und die Akzeptanz ist in groBen Teilen der Offentlichkeit noch gering. In der vorliegenden Arbeit wird eine optimierte LOsung zu dieser Problematik aufgezeigt, speziell flir eine Reststoffgruppe. Dabei handelt es sich um feste Riickstiinde aus der Rauchgasreinigung industrieller und offentlicher Feuerun gen, die fossile Energietrager einsetzen. Fiir diese Materialien werden neuartige Entsorgungswege mit verwertungsorientierten Autbereitungen auf regionaler Ebene konzipiert und unter technischen, okologischen und okonomischen Ge sichtspunkten bewertet."

Die sachgerechte Prasentation von umweltbezogenen Daten gewinnt aufgrund der steigenden Komplexitat der Umweltprobleme eine immer grossere Bedeutung. Aufgrund der Unterschiede in den Benutzerkreisen werden die Anforderungen an Visualisierungstechniken breiter. Das Buch gibt einen Uberblick uber den derzeitigen Stand in Forschung und Praxis. Dabei werden Querbezuge zu Simulation und Modellbildung, Umweltinformationssystemen und Schnittstellenproblematik hergestellt.

Okologie und Okonomie: Ihre Integration stellt eine wichtige Aufgabe fur Ingenieure heute und in der Zukunft dar. Das Buch liefert eine zusammenfassende Darstellung der Analyse, Bewertung und Nutzung okologischer Systeme durch den Menschen und seine Technik. Die Notwendigkeit der Einpassung okonomischer Nutzung in die okologischen Potentiale und die Grenzen dieser Nutzung werden deutlich gemacht. Der Leser erkennt sehr schnell, dass alle Systeme, auch Okosysteme, nach relativ einfachen gemeinsamen Grundprinzipien arbeiten, dass jedes aber doch seine besondere Struktur hat, seine eigenen Schwachstellen und Nutzungsoptionen. Der Autor hat das Buch in einer Weise verfasst, die auch dem Nichtfachmann die Problematik der Nutzung von okologischen Systemen aufzeigt.

Etwa 70 Fachleute aus Wissenschaft, Wirtschaft und Politik diskutierten im Dezember 1989 auf einem Seminar der WE Heraeus-Stiftung die "Optionen und Prioritaten kunftiger Forschungs- und Technologiepolitik". Angesichts der drohenden globalen Klimaveranderungen und anderer Umweltprobleme ging es vor allem um eine okologisch orientierte Forschungs- und Technikpolitik, die unsere Zukunft langfristig sichert. Diese Politik muss folgende Kriterien erfullen: - Weite Zeithorizonte (100 Jahre), - Weltsolidaritat (Nord/Sud-Lander), - moglichst kleine Risiken fur die Bevolkerung (z.B. Radioaktivitat), - Wohlfahrts- statt Wirtschaftswachstum. In dem hier vorgelegten Tagungsbericht hat Prof.Dr. Helmar Krupp als wissenschaftlicher Leiter des Seminars die Referate und Diskussionsergebnisse zusammengestellt. Der Bericht gibt einen reprasentativen Uberblick uber den internationalen Stand der Forschungs- und Technikpolitik und skizziert anhand konkreter Beispiele die kunftigen Anforderungen an diese Politik.

A new weapon is emerging to help us fight climate change. It is becoming feasible to take carbon dioxide from power stations and industry, and lock it away safely before it can enter the atmosphere. In the next few years, major demonstration programmes will start up in the USA, EU and elsewhere. But can carbon capture compete with other low-carbon technologies, is it safe and environmentally-friendly, and will people and governments accept it? "Capturing Carbon" examines the need for carbon capture, and the technologies, existing and emerging, that make it work. It describes geological storage and, uniquely, compares it to biological carbon sequestration in soils and forests. It looks at the costs, the economics, and how big a contribution carbon capture can make to avoiding dangerous climate change. It covers the policies that need to be in place, the public reaction, and the opportunities for business. Finally, it gives a hard-headed description of the risks of carbon capture projects. The book is the first comprehensive yet accessible study of the subject. It is a vital resource for environmentalists, policy-makers, investors, academics, industry specialists and anyone else wishing to understand this fast-moving field.

During the past years, it has been shown that the results of many reactions in the environment have led to the degradation or detoxification of environmental pollutants. The chemical aspects of environmental pollutants have therefore begun to take on great significance. The Chemistry of Pollution provides an excellent overview of the important chemical aspects of pollution occurring in the atmosphere, in water and in soil. Presented in the book are:

• commonly known harmful substances, such as carbon monoxide, heavy metals, and sulfur dioxide
• toxins in food and basic consumer goods
• radioisotopes, such as plutonium and uranium.

In Toxic Matters, Monica Seger considers two Italian environmental disasters: an isolated factory explosion in Seveso, just north of Milan, in 1976 and the ongoing daily toxic emissions from the Ilva steelworks in the Apulian city of Taranto. Both have exposed residents to high concentrations of the persistent organic pollutant known as dioxin. Although different in terms of geography and temporality, Seveso and Taranto are deeply united by this nearly imperceptible substance, and by the representational complexities it poses. They are also united by creative narrative expressions, in literary, cinematic, and other forms, that push back against dominant contexts and representations perpetuated by state and industrial actors.Seger traces a dialogue between Seveso and Taranto, exploring an interplay between bodies, soil, industrial emissions, and the wealth of dynamic particulate matter that passes in between. At the same time, she emphasizes the crucial function of narrative expression for making sense of this modern-day reality and for shifting existing power dynamics as exposed communities exercise their voices. While Toxic Matters, is grounded in Italian cases and texts, it looks outward to the pressing questions of toxicity, embodiment, and storytelling faced by communities worldwide.

Plastic pollution has been a growing concern globally, especially under the COVID-19 pandemic due to the use of personal protective equipment. While many engineers and environmental scientists have been addressing global plastic pollution, special attention must also be paid to smaller plastics such as micro- and nano-plastics. These smaller plastics pollute and affect the health of the public, environment, and marine life. Risk assessment of plastics is required to evaluate currently available treatment technologies and identify the significance of plastic pollution. Assessing the Effects of Emerging Plastics on the Environment and Public Health assesses the harmful effects of plastics on the environment and public health. It evaluates the potential risks of micro- and nano-plastics and reviews applications of modeling tools and prevention approaches using technologies to minimize plastic pollution through the development of biodegradable plastics or recycling and reusing plastics in environmentally friendly ways. Covering topics such as agroecosystems, preventive measures, and bioplastics, this book is an indispensable resource for environmentalists, environmental engineers, government officials, libraries, business leaders, students and educators of higher education, academicians, and researchers.

Drinking water availability and safety is a major challenge faced globally and is highly pronounced in developing countries worldwide. Lack of safe potable water across the globe can be attributed to industrial pollution, climate change and other human activities that result in a spectrum of chemical, physical and biological pollutants entering a water body. Although efforts to solve this problem are well underway worldwide, challenges still exist. This book shines a light on drinking water treatment methods and scale of operation specifically for the developing countries. Covering both conventional and emerging treatment technologies, the authors discuss the removal of chemical, physical and biological pollutants from drinking water, with a focus on developing countries. Conservation by rainwater harvesting, wastewater reuse, and selection criteria of feasible methods are considered in the context of issues relevant to Africa, Asia, Latin America and the Caribbean. With case studies connecting theory to real world matters, showcasing efficiencies and drawbacks, this book is ideal for graduate and postgraduate level course use in engineering departments or for self-study and research.

According to the Global Burden of Disease 2019 study, air pollution from fine particulate matter caused 6.4 million premature deaths and 93 billion days lived with illness in 2019. Over the past decade, the toll of ambient air pollution has continued to rise. Air pollution's significant health, social, and economic effects compel the World Bank to support client countries in addressing air pollution as a core development challenge. This publication estimates that the global cost of health damages associated with exposure to air pollution is $8.1 trillion, equivalent to 6.1 percent of global GDP. People in low- and middle-income countries are most affected by mortality and morbidity from air pollution. The death rate associated with air pollution is significantly higher in low-and lower-middle income countries than in high-income countries. This publication further develops the evidence base for air-quality management through up-to-date estimates of air pollution's global economic costs. The analyses presented here build on previous cost estimates by the Bank and its partners, as well as on more comprehensive air-quality data from monitoring stations in many cities across the world. By providing monetary estimates of air pollution's health damages, this publication aims to support policy makers and decision-makers in client countries in prioritizing air pollution amid competing development challenges. Its findings build a robust economic case to invest scarce budgetary resources in the design and implementation of policies and interventions for improving air quality. Such investments will deliver benefits for societies at large, and particularly for vulnerable groups. This publication builds a strong case for scaling up investments for air pollution control in low-and middle-income countries.

The Anthropocene has arrived riding a wave of pollution. From "forever chemicals" to oceanic garbage patches, human-made chemical compounds are seemingly everywhere. Concerned about how these compounds disrupt multiple lives and ecologies, environmental scholars, activists, and affected communities have sought to curb the causes of pollution, focusing especially on the extractive industries. In Worlds of Gray and Green, authors Sebastian Ureta and Patricio Flores challenge us to rethink extraction as ecological practice. Adopting an environmental humanities analytic lens, Ureta and Flores offer a rich ethnographic exploration of the waste produced by Chile's El Teniente, the world's largest underground mine. Deposited in a massive dam, the waste-known as tailings-engages with human and non-human entities in multiple ways through a process the authors call geosymbiosis. Some of these geosymbioses result in toxicity and damage, while others become the basis of lively novel ecologies. A particular kind of power emerges in the process, one that is radically indifferent to human beings but that affects them in many ways. Learning to live with geosymbioses offers a tentative path forward amid ongoing environmental devastation.
