  • 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.

  • There are two main reasons why the chemical process industry should be motivated to reduce energy consumption and CO 2 emissions: rising concerns in companies, the public and scientifi c community about climate change or global warming, and the increasing fraction of energy in manufacturing costs. ‘ Climate change ’ [1] in this context, means a change of climate, which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods....

  • Concentrated animal feeding operations (CAFOs) are part of a recent agricultural trend toward large-scale, corporate-owned and managed livestock production. A far cry from the traditional family farm, CAFOs have lowered prices and increased production—but at a cost. While some of the problems CAFOs can cause are economic and related to small farm and farming community culture, or societal with a focus of the animal rights activism groups, other problems are ecological and environmental and will only be solved by intelligently crafted and enforced legislation....

  • 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’.

  • 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.

  • 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.

  • Honey bees (Apis mellifera L.) are the main pollinating agents for numerous plants and fruit trees and, hence, play a key role in agriculture and more generally in the maintenance of ecological biodiversity. Although these social insects are not the targets of all the different agrochemical treatments used in crop protection, they are widely affected by pesticides.

  • Marine birds are equally at home on land, in the air, and in the water. While many organisms can go from land to water (amphibians, some reptiles, some insects), others generally live in only one medium during their lives. Marine birds switch from one to the other, often daily. Such flexibility requires unique physiological and morphological adaptations to the environment, a medium that has also exerted selective forces on the behavior, ecology, and demography of these birds.

  • The environment is key to sustaining human economic activity and well-being, for without a healthy environment, human quality of life is reduced. Most people would agree that there are also many reasons to protect the environment for its own inherent worth, and especially to leave a legacy of fully functioning natural resources. Sustainable land management refers to the activities of humans and implies that activity will continue in perpetuity. It is a term that attempts to balance the often conflicting ideals of economic growth and maintaining environmental quality and viability....
