Chemical substances, physical agents and built structures bear various types of hazard due to their immanent toxic, mutagenic, carcinogenic, reprotoxic and sensitizing character or being destructive for the immune and hormone system. The first step in managing the environment contaminated by chemical substances is to characterize the hazard and quantify their risk manifested when the chemical substances interact with the environment. Chemical models - using only chemical analytical data - are still the most widespread ones for the assessment of adverse effects and the fate and behavior of chemicals in the environment. The chemical models rely on the assumption that the adverse effect is proportional to the concentration, which does not apply in most cases. Other models, such as biological and ecological ones or the regression models are discussed in detail and compared to each other. Environmental risk management has two compartments: risk assessment and risk reduction. Environmental risk comes to a large extent from adverse effects of chemicals and contaminated land; that is why measuring and testing these adverse effects play a key role in risk management.Environmental Toxicology deals with direct measurement of adverse effects of pure chemicals or environmental samples. This book overviews hundreds of standardized and non-standardized, generic and site-specific, conventional and innovative, animal and alternative test methods and demonstrates the utilization of their results for the purposes of regulation and managing environmental risk. The volume gives a general overview on environmental toxicology adapted for engineers. In addition to human, aquatic and terrestrial toxicity measuring methods, new trends in environmental analytics and the integration and complementary use of chemical analyses and the testing of effects are described. Bioavailability and accessibility as key parameters are detailed and the interactive and dynamic testing for their characterization is introduced. Great emphasis is placed on the evaluation and interpretation of environmental fate and adverse effect data as well as the simulation of environmental processes and effects in microcosms and mesocosms.

Chemical substances, physical agents and built structures exhibit various types of hazard due to their inherent toxic, mutagenic, carcinogenic, reprotoxic and sensitizing character or damaging to the immune and hormone system. The first steps in managing an environment contaminated by chemical substances are characterization of hazards and quantification of their risks. Chemical models - using only analytical data - are still the most widely used applications for assessing potential adverse effects and the fate and behavior of chemicals in the environment. Chemical models rely on the assumption that the adverse effect is proportional to the concentration, which in most cases is incorrect. In this volume, other models such as biological and ecological or regression models are discussed in detail and compared. Environmental risk management has two subsections: risk assessment and risk reduction. Environmental risk, to a large extent, arises from the adverse effects of chemicals and contaminated land; that is why measuring and testing these effects plays a key role in risk management. "Environmental Toxicology" deals with direct measurement of adverse effects of pure chemicals or environmental samples. This book has therefore been created specifically for engineers and gives a general overview of environmental toxicology. It provides an overview of hundreds of standardized and nonstandardized, generic and site-specific, conventional and innovative, animal and alternative test methods, and demonstrates how to apply these results to the regulation and management of environmental risk. In addition to human, aquatic and terrestrial methods for measuring toxicity, new trends in environmental analytics and the integration and complementary use of chemical analyses and the testing of effects are described. Bioavailability and accessibility as key parameters are detailed and the interactive and dynamic characterization of contaminants in soil is introduced. Emphasis is placed on the evaluation and interpretation of environmental fate and adverse effect data as well as the simulation of environmental processes and effects in microcosms and mesocosms.

The four volumes of the book series "Engineering Tools for Environmental Risk Management" deal with environmental management, assessment & monitoring tools, environmental toxicology and risk reduction technologies. This last volume focuses on engineering solutions usually needed for industrial contaminated sites, where nature's self-remediation is inefficient or too slow. The success of remediation depends on the selection of an increasing number of conventional and innovative methods. This volume classifies the remedial technologies and describes the reactor approach to understand and manage in situ technologies similarly to reactor-based technologies. Technology types include physicochemical, biological or ecological solutions, where near-natural, sustainable remediation has priority. A special chapter is devoted to natural attenuation, where natural changes can help achieve clean-up objectives. Natural attenuation and biological and ecological remediation establish a serial range of technologies from monitoring only to fully controlled interventions, using ' just' the natural ecosystem or sophisticated artificial living systems. Passive artificial ecosystems and biodegradation-based remediation - in addition to natural attenuation - demonstrate the use of these 'green' technologies and how engineering intervention should be kept at a minimum to limit damage to the environment and create a harmonious ecosystem. Remediation of sites contaminated with organic substances is analyzed in detail including biological and physicochemical methods. Comprehensive management of pollution by inorganic contaminants from the mining industry, leaching and bioleaching and acid mine drainage is studied in general and specifically in the case of an abandoned mine in Hungary where the innovative technology of combined chemical and phytostabilization has been applied. The series of technologies is completed by electrochemical remediation and nanotechnologies. Monitoring, verification and sustainability analysis of remediation provide a comprehensive overview of the management aspect of environmental risk reduction by remediation. This book series focuses on the state of knowledge about the environment and its conscious and structured application in environmental engineering, management and decision making.

The past fifty years have seen rapid development of public and governmental awareness of environmental issues. Engineers and scientists have made tangible contributions to environmental protection. However, further theoretical and practical developments are necessary to address mankind 's growing demands on the environment. Construction for a Sustainable Environment includes recent developments relating to construction and the environment, including: (1) engineered disposal of wastes; (2) treatment of contaminated and derelict land; (3) sustainable construction and infrastructure; (4) supporting the natural environment. Construction for a Sustainable Environment presents clear evidence that common sustainability issues are encountered throughout the world and that only a concerted, international and interdisciplinary approach can tackle these issues.

The theory and practice of reducing the environmental risk of chemicals is a key issue in environmental protection. This volume deals with remediation technologies and introduces their functional classification, applicability and relation to natural risk reduction processes. We demonstrate how the proper characterization and understanding of the environmental technologies helps decision making and finding the problem-suited engineering tools. The reactor approach is an important model for "in situ "remediation which supports professionals in applying well-controlled bioengineering or eco-engineering tools combined with conventional physical or chemical technologies and processes. The first task is finding the best catalyst which may be a chemical agent, a living organism or the soil community. The second task is ensuring optimal conditions for the operation of the catalyst by environmental parameter control; redox-potential manipulation; optimal nutrient supply, etc. The final engineering task is the verification of the applied technology feedbacks to the complex environmental risk management. The risk management and decision-making procedure relies to a great extent on innovation, problem-specific solutions, evaluation and verification of remedial technologies, as well as their integration into a risk reduction strategy.
The comprehensive overview on the approaches, concepts and technologies is followed by the analysis of natural attenuation, biological and ecological engineering tools, artificial ecosystems and living machines, biodegradation-based remediation, including those based on co-metabolism, bioleaching, phytoremediation, physical, chemical, electrochemical and thermal remediation. The book deals with nanotechnologies, reactive barriers and zones, soil amelioration and remediation using wastes. General technology descriptions and concrete applications are discussed. Risk reduction strategies and options, decision making, fitting the strategies and technologies to the problem or the contaminated site are also dealt with in detail.
The evaluation of a technology in advance in aid of decision making and planning, during technology application for the validation of the plan, and after the application for verifying the technology are differentiated and explained in detail. The methodologies of risk assessment, socio-economic assessment, eco-efficiency and life-cycle assessment as well as multicriteria-analysis as an aggregating tool are presented and demonstrated by examples.

Industrial, agricultural, residential land uses and the connected discharge of chemical substances cause environmental problems world-wide: contaminated air, water and soil, dead rivers, polluted sites, abandoned areas, derelict land, degraded soil, and endangered ecosystem and humans. This volume provides an overview on the behavior and function of the healthy environment, the capacity of the ecosystem to serve humanity and compensate for adverse changes. The prime contributors to these changes such as production and use of chemical substances, abandoned and contaminated land, chemical agriculture, mining and the complex waste problem are introduced. Medication for environmental health problems is environmental risk management, which has two compartments: risk assessment and risk reduction. The target is an acceptable risk level. Environmental risk management can be structured horizontally and vertically. The horizontal structure of the management includes environmental compartments such as air, surface water, groundwater, soil and sediments; contaminating chemical substances or wastes as well as the land uses and the exposed receptors.The vertical structure includes the management tools, the environmental assessment and monitoring tools; preventive, protective and remedial technologies; evaluation and interpretation and decision making. The horizontal and vertical structures result in several combinations, most of which are reviewed in the book. Knowledge is the basis of decision making. Good management practice should be based on high-quality information. Information comes from proper data evaluation and interpretation. Data collection, structuring and selection and their conversion to information provide an information system which is vital for the management of environment. The sustainable future requires from us to adopt a humble attitude toward nature by integrating ethics with scientific and engineering knowledge. Otherwise humans will put themselves in jeopardy by inflicting damage to the environment. In addition to the right attitude, efficient and innovative engineering tools are necessary for the long-term management of the environment.Even current best management practices are insufficient to achieve the goals of holistic environmental protection and land use - we need innovative technologies, integrated evaluation and a holistic approach. The focus of this book is environmental knowledge and its conscious and structured application in environmental management and decision making.

Deponieabdichtungssysteme sollen ihre Funktionsfahigkeit uber einen weitaus langeren Zeitraum als konventionelle Bauwerke erhalten. Bei Basisabdichtungen kommt erschwerend hinzu, dass sie praktisch nicht zu reparieren sind, keiner Wartung unterzogen werden konnen und Schadensfalle, d. h. Grundwasserkontaminationen erst mit grosser zeitlicher Verzogerung registriert werden konnen. Daher ist die Optimierung von Deponieabdichtungen besonders im Hinblick auf das Langzeitverhalten der zum Einsatz kommenden Baumaterialien von grossem Interesse. Neueste Erkenntnisse erlauben einen aktuellen Einblick in die Eigenschaften von Materialien und deren Langzeitverhalten, vor allem in ihrer Funktion zur Erfullung des Vorsorgeprinzips fur Deponien als Bauwerke mit hoher sicherheitstechnischer Relevanz.

The co-disposal of domestic waste with industrial waste can represent a serious hazard to prime sources of drinking water throughout the world.
