  • This work inevitably sprang out of our environmental biotechnology modules at the University of Durham, but it is not intended to be just another ‘book of the course’. Though it is clearly rooted in these origins, it reflects our wider, and rather varied, experiences of the field. In many respects, we have been fortunate; teaching has undoubtedly drawn on the ‘theory’, while our own consultancy has tended to focus us on the ‘application’.

  • How are pollutants transformed after their release into the environment? How are organisms exposed, and how do physiological alterations impact population dynamics and community structure? What direct or indirect impacts occur? As early as the 50s and 60s people living near industrial plants began to recognize undesirable changes in their environment - and to ask these very questions. The discipline of environmental toxicology addresses these questions.

  • An environmental impact statement (EIS), under United States environmental law, is a document required by the National Environmental Policy Act (NEPA) for certain actions "significantly affecting the quality of the human environment".[1] An EIS is a tool for decision making. It describes the positive and negative environmental effects of a proposed action, and it usually also lists one or more alternative actions that may be chosen instead of the action described in the EIS. Several US state governments require that a document similar to an EIS be submitted to the state for certain actions.

  • The detection of pharmaceutical residues remained elusive until instruments such as liquid chromatography and mass spectrometry became commonplace in environmental laboratories. The documentation of the occurrence of pharmaceutical residues and endocrine disrupting chemicals in water resources has raused questions about their long-term effects in the ecosystem and their potential effects on human health.

  • A compilation of the most important aerosol chemical processes involved in known scientific and technological disciplines, Aerosol Chemical Processes in the Environment serves as a handbook for aerosol chemistry. Aerosol science is interdisciplinary, interfacing with many environmental, biological and technological research fields. Aerosols and aerosol research play an important role in both basic and applied scientific and technological fields. Interdisciplinary cooperation is useful and necessary.

  • Much of the convenience of modern life resides in sheet metal, the cowling shield of most machines and appliances. However, the load that this takes off human shoulders has to be carried elsewhere, and the Earth has borne the burden. Many of us woke up to the environmental cost when over a century of industrialization finally surpassed the capacity of nature to assimilate it. International in scope, Heavy Metals in the Environment: Using Wetlands for Their Removal discusses wetland functions and heavy metal contamination.

  • Contaminated bottom sediments and their negative impacts on water quality are a major problem in surface waters throughout the United States as well as in many other parts of the world. Even after elimination of the primary contaminant sources, these bottom sediments will be a main source of contaminants for many years to come. In order to determine environmentally-effective and cost-effective remedial actions, the transport and fate of these sediments and associated contaminants must be understood and quantified.

  • This text has been written primarily for the specialist market of second and third year undergraduate and post-graduate students of economics. The clear explanations and basic principles that underpin the text, however, make it readily accessible to non-economists coming to environmental economics from diverse programmes of study. Natural Resource and Environmental Economics is among the leading textbooks in its field.

  • Environmental toxicology is the study of the impacts of pollutants upon the structure and function of ecological systems. For the purposes of this text, the emphasis will be upon ecological structures, from the molecular to the individual organism to the community and the ecosystem. The broad scope of environmental toxicology requires a multidisciplinary approach of a variety of specialists.

  • The guidelines are targeted at public health professionals involved in prevent- ing health risks of environmental exposures as well as specialists and authorities involved in the design and use of buildings, indoor materials and products. The guidelines are based on the accumulated scientific knowledge available at the time of their development. They have the character of recommendations. Nev- ertheless, countries may wish to use the guidelines as a scientific basis for legally enforceable standards.

  • There is now a body of evidence suggesting that the occurrence and course of schizophrenia are affected by a variety of environmental factors. The Environment of Schizophrenia draws upon our knowledge of these factors in order to design innovations that will decrease its incidence and severity, while enhancing the quality of life for sufferers and their relatives. Examining environmental forces operating at the individual, domestic and broad societal levels, Richard Warner proposes feasible interventions such as...

  • Organic carbon concentrations can be reduced by enhanced coagulation, granular activated carbon or membrane filtration, but this fact can also lead to increased in brominated THMs (Black et al, 1996.). A combination of coagulation, ozonation, and biofiltration can effectively reduce trihalomethane and haloacetic acid formation potential (Chaiket et al, 2002.). Natural organic matter (NOM), the main precursor of DBPs, can also be removed by media filters coated with iron oxide

  • A newcomer to the scene, aerobic granulation is on its way to becoming the hot new technology for high-efficiency wastewater treatment. Thus far, intensive research has been conducted with regard to the understanding of the mechanism of aerobic granulation in sequencing batch reactors (SBR) and its application in treating a wide variety of municipal and industrial wastewater. This basic research has promoted the technology from laboratory-study all the way to the present pilot- and full-scale application.

  • The specific problems associated with concrete and concreting in hot environments have been recognised for some decades. This recognition has manifested itself over the years at a few symposia and in hundreds of papers where relevant research results and field observations were presented and discussed. In other publications the practical conclusions from these available data and experiences have been summarised in the form of guidelines for hot climate concreting.
