Sampllng Fundamental Aspects 2 Sampling: Fundamental aspects Reimar Leschber Institut fuer Wasser-, Boden- und Lufthygiene des Bundesge- sundheitsamtes, Berlin-Dahlem, Federal Republic of Germany Chairman of Working Party 2, COST 681 Protection of the environment increasingly requires the de- velopment of a recycling society using 'secondary raw ma- terials' instead of natural resources wherever possible. Among the methods of recycling the agricultural use of sludge is a traditional one and a good example with a long history of a meanlngful use of waste material. Increasing demands of water pollution control in the last de- cades leading to intensified and extended sewage treatment processes and thus to an increase of the sludge quantity have caused problems in this field in general. In addition, there were local problems of industrial pollution which have led to an increase of harmful substances in municipal sewage sludges. So, when the Concerted Action COST 68 was set up to study the beneficial and harmful effects of the agricultural use of sludge, investigation of harmful substances in the sludges and their environmental effects was 9ne of the main tasks of work. Although the progress of analytical techniques enabled the environmental authorities and institutions to determine harmful substances in sludges with great accuracy, it became clear that unsatisfactory results and an incomplete reproduc- ibility of analytical findings often were not due to shortcom- ings in the analytical procedure itself but to a preceding in- vestigation step: Improper sampling and sample preparation.
Five billion people, at present the world population, inevitably affect the quality of the environment. The general public in an increasing number of countries is getting more and more concerned about this deterioration in quality. As a result many people cast doubts upon the desirability of the increase in energy consumption, the production of superfluous goods, ever-growing waste flows, harmful emissions of industrial processes, and so on. Actually, no one can simply ignore these issues. For instance, the authorities could introduce more environmental legislation aiming at a healthy environment; industries could change to cleaner production processes; the public at large should assume an even more conservation-minded attitude rather than confine themselves to shaking a finger at 'the industry'. In short, in all sectors of society there are often numerous ways and means of curbing environmental pollution. Clearly, environmental technology - the development and application of techniques to identify, quantify and reduce environmental problems - can make a substantial contribution here in many situations. Until now a large number of such new techniques have been developed. Many of these techniques not only appear to add greatly to reducing the burden on the environment, they sometimes also offer interesting economic advantages (savings in raw material and energy, etc.).
Landfilling of waste has increased dramatically over recent years and there have been many examples of landfills which are unacceptable on environmental and health grounds. This is one of a group of international reference books which address this problem, specifically in this case covering the strongly contaminated wastewater developed from landfills.
Solid waste is a major urban challenge worldwide and decisions over which technologies or methods to apply can have beneficial or detrimental long-term consequences. Inappropriate management of solid waste can lead to damaging environmental impacts, particularly in the megacities of the Global South. Urban Recycling Cooperatives explores the multiple narratives and interdisciplinary nature of waste studies, drawing attention to the pressing social, economic and environmental challenges related to waste management. The book asks questions such as: how do we define waste and our relation to it; who is involved in dealing with waste; and what power interactions become manifest over issues of accessing and managing waste? In recent years informal cooperatives have emerged, devoted to recycling household and business waste before reclassifying it and redirecting it to the authorities. Hence, these workers are able to reclaim significant amounts of natural resources and thus contribute to the saving of resources and lessened waste management expenditures. With particular reference to the Brazilian megalopolis of Sao Paulo, this book describes this paradigm shift in the general understanding of waste as unwanted discard towards the recognition of waste as a resource that must be recovered for reuse or recycling. It would be of interest to students and policy makers working in international development and waste management.
Biofilms represent the natural living style of microbial communities and play a pivotal role in biogeochemical cycles and natural attenuation. Biofilms can be engineered for biodegradation and biotransformation of organic and inorganic contaminants, for both in situ bioremediation and ex situ treatment in bioreactors. This book focuses on microbial biofilms and their potential technological applications for sustainable development. It covers recent advances in biofilm technologies for contaminant remediation coupled to recovery of resources and serves as a complete reference on the science and technology behind biofilm mediated bioremediation and wastewater treatment.
A successful modern heavy metal control program for any industry will include not only traditional water pollution control, but also air pollution control, soil conservation, site remediation, groundwater protection, public health management, solid waste disposal, and combined industrial-municipal heavy metal waste management. In fact, it should be a total environmental control program. Comprehensive in scope, Heavy Metals in the Environment provides technical and economical information on the development of a feasible total heavy metal control program that can benefit industry and local municipalities. The book discusses the importance and contamination of metals such as lead, chromium, cadmium, zinc, copper, nickel, iron, and mercury. It covers important research of metals in the environment, the processes and mechanisms for metals control and removal, the environmental behavior and effects of engineered metal and metal oxide nanoparticles, environmental geochemistry of high arsenic aquifer systems, nano-technology applications in metal ion adsorption, biosorption of metals, and heavy metal removal by expopolysaccharide-producing cyanobacteria. The authors delineate technologies for metals treatment and management, metal bearing effluents, metal-contaminated solid wastes, metal finishing industry wastes and brownfield sites, and arsenic-contaminated groundwater streams. They also discuss control, treatment, and management of metal emissions from motor vehicles. The authors reflect the breadth of the field and draw on personal experiences to provide an in-depth presentation of environmental pollution sources, waste characteristics, control technologies, management strategies, facility innovations, process alternatives, costs, case histories, effluent standards, and future trends for each industrial or commercial operation. The methodologies and technologies discussed are directly applicable to the waste management problems that must be met in all industries.
This book examines the very current issue of wood waste treatment to a solid biofuel for energy recovery. The book is dedicated to research in the densification processes of wood waste and its mathematical description for uniaxial densification into compact biofuels - briquettes. This monograph, derived from an experimental research of densification process in laboratory conditions and also in real technologies in practice, provides a thorough understanding of the influencing parameters impact during densification of wood waste into solid biofuel. The book shows the experimental strategy to determine the effects of individual parameters and specifies their impact on the resulting density of the briquettes. The publication also defines the level of importance of the results in terms of optimization of the densification machine's pressing chamber. Using a designed mathematical model, which was a result of experimental research and which can serve to predict the density of briquettes for some predefined densification conditions and can aid in the design of densification machines, the author has made this topic accessible beyond his discipline, biofuels producers and the academic community.

Electronic waste, which includes everything from refrigerators to smartphones, is one of the world's fastest growing waste streams. Often these items are simply discarded as new technology becomes available. A huge amount of electronic waste is generated globally and currently only around 20% of it is recycled. The complex mixture of materials and components within electronic waste makes it difficult to manage and many of these components can pose hazards to human health or the environment if not disposed of carefully. There have been significant changes in the global approach to electronic waste management and the legislation around it since the publication of the first edition of Electronic Waste Management. This new edition provides an updated overview across the world as well as presenting new chapters on current issues in recycling and management of this waste. This is an essential reference not only for those working in recycling and waste management, but also for those working in manufacturing and product development who wish to consider the full lifecycle of their products. It also provides valuable insights for policymakers developing more environmentally sound and sustainable systems and strategies for the management of electronic waste.

Biotechnology for Treatment of Wastes Containing Metals addresses various aspects related to different wastes that have a metallic content and represent a serious risk for the environment and human health. These wastes, due to their physical and chemical characteristics, have been the object of studies which have led to the development of different technologies in recycling, reuse or adequate disposal, biotechnology being one of these alternatives. Biotechnology offers a range of options for the treatment of types of waste using microorganisms, biomass and their by-products. The mechanisms involved in these waste treatment processes are diverse and complex, and its optimization and efficiency is multifactorial. This text contains nine chapters related to the problem of the metal contamination in the environment as well as some of the different biotechnological alternatives that have been applied for the reduction and/or recovery of metal contamination.
A practical, systems-based approach for a more sustainable farming operation To many people today, using the words "factory" and "farm" in the same sentence is nothing short of sacrilege. In many cases, though, the same sound business practices apply whether you are producing cars or carrots. Author Ben Hartman and other young farmers are increasingly finding that incorporating the best new ideas from business into their farming can drastically cut their wastes and increase their profits, making their farms more environmentally and economically sustainable. By explaining the lean system for identifying and eliminating waste and introducing efficiency in every aspect of the farm operation, The Lean Farm makes the case that small-scale farming can be an attractive career option for young people who are interested in growing food for their community. Working smarter, not harder, also prevents the kind of burnout that start-up farmers often encounter in the face of long, hard, backbreaking labor. Lean principles grew out of the Japanese automotive industry, but they are now being followed on progressive farms around the world. Using examples from his own family's one-acre community-supported farm in Indiana, Hartman clearly instructs other small farmers in how to incorporate lean practices in each step of their production chain, from starting a farm and harvesting crops to training employees and selling goods. While the intended audience for this book is small-scale farmers who are part of the growing local food movement, Hartman's prescriptions for high-value, low-cost production apply to farms and businesses of almost any size or scale that hope to harness the power of lean in their production processes.
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.
