The authors address the many negative impacts on regional economies and the environment of poorly planned and inadequate winter road operations, and they make a strong case for the myriad benefits of environmentally sustainable concepts and practices. Best practice applications of materials, processes, equipment, and associated technologies and how they can improve the effectiveness and efficiency of winter operations, optimize materials usage, and minimize cost, corrosion, and environmental impacts are all covered in depth. Provides the first up-to-date, authoritative and comprehensive overview of best practices in sustainable winter road operations currently in use around the world Covers materials, processes, equipment, and associated technologies for sustainable winter road operations Brings together contributions by an international all-star team of experts with extensive experience in designing, implementing, and managing sustainable winter road operations Designed to bring professionals involved in transportation and highway maintenance and control up to speed with current best practice Sustainable Winter Road Operations is essential reading for maintenance professionals dealing with snow and ice control operations on highways, motorways and local roads. It is a valuable source of information and guidance for decision makers, researchers, and engineers in transportation engineering involved in transportation and highway maintenance. And it is an ideal textbook for advanced-level courses in transportation engineering.




Environmental Issues in Chemical Perspective


Book Description

An in-depth presentation of the chemistry required to evaluate the choices we must make regarding our environment, this study has four parts: energy, the atmosphere, the hydrosphere, and the biosphere. Each part is followed by problem sets that require the application of chemical principles to such issues as dwindling natural gas and petroleum resources; fission and fusion as energy sources; CO2 build-up and the greenhouse effect; automobile emission control; acid rain; eutrophication of lakes; lead, mercury, and cadmium poisoning; and environmental links to cancer. An answer manual for the problems is included. Social, political, and economic concerns are also covered. The authors show how chemists and non-chemist decision-makers can take account of each other's perspectives.




Strategies to Mitigate the Impacts of Chloride Roadway Deicers on the Natural Environment


Book Description

"TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 449 : Strategies to Mitigate the Impacts of Chloride Roadway Deicers on the Natural Environment documents the range of methods, tools, and techniques used by transportation agencies to minimize the environmental impact of chloride-based roadway deicers"--Publisher's description.




Regulating Chemical Accumulation in the Environment


Book Description

The environment has become exposed to a range of damaging contaminants from a wide variety of sources. Regulation of and legislation against offending parties has frequently been hampered because of the difficulty of co-operation between disparate disciplines in the natural, social and political sciences. This volume forms the conclusion of five years' collaboration between toxicologists, economists and lawyers in the understanding and solution of the problem of accumulative chemicals. As well as a case study of the accumulation of pesticides in groundwater in one particular region (the European Union), the book forms a general study of the value of interdisciplinary approaches in environmental policy making. The volume will be a valuable resource for a broad group of academics and researchers in the area of environmental science and environmental policy. It will also form a useful supplementary reference text for courses in environmental policy, science, economics and toxicology.




Transport and Fate of Chemicals in the Environment


Book Description

What happens when a chemical is released into the environment? It diffuses, disperses, adsorbs, reacts, and/or changes state. To predict and analyze this process, the mathematics of diffusion is applied to lakes, rivers, groundwater, the atmosphere, the oceans, and transport between these media. A sustainable world requires a deep understanding of the transport of chemicals through the environment and how to address and harness this process. This volume presents a succinct and in-depth introduction to this critical topic. Featuring authoritative, peer-reviewed articles from the Encyclopedia of Sustainability Science and Technology, Transport and Fate of Chemicals in the Environment represents an essential one-stop reference for an audience of researchers, undergraduate and graduate students, and industry professionals.




Residues


Book Description

Residues offers readers a new approach for conceptualizing the environmental impacts of chemicals production, consumption, disposal, and regulation. Environmental protection regimes tend to be highly segmented according to place, media, substance, and effect; academic scholarship often reflects this same segmented approach. Yet, in chemical substances we encounter phenomena that are at once voluminous and miniscule, singular and ubiquitous, regulated yet unruly. Inspired by recent studies of materiality and infrastructures, we introduce “residual materialism” as a framework for attending to the socio-material properties of chemicals and their world-making powers. Tracking residues through time, space, and understanding helps us see how the past has been built into our present chemical environments and future-oriented regulatory systems, why contaminants seem to always evade control, and why the Anthropocene is as inextricably harnessed to the synthesis of carbon into new molecules as it is driven by carbon’s combustion.







Highway Deicing


Book Description

Examines the total cost of salt and calcium magnesium acetate (CMA), including the indirect cost of application and indirect costs to the environment, infrastructure, and motor vehicles. This report focuses on defining the true cost of salt, which is the most popular deicer and the standard of comparison for most other deicing products.




Chemicals in the Environment


Book Description

The teaching of Chemistry at the introductory stage becomes each day a more challenging task as the subject matter becomes more diverse and more complex. These challenges have evoked a series of responses the present set of introductory chemistry monographs is one such. The teaching of chemistry recognises a number of problems, that confront those who select text books. In order to overcome these problems, this volume Chemicals in the Environment one of about fifty in the Chemistry Monograph Series is introduced. Each volume is independent of the others deals with one of Chemistry topics and constitutes a complete entity. Each volume is more comprehensive than can be possible in a single volume text. It is intended to provide a range, of topics to cover most undergraduate and chemistry main courses of study. These volumes can be used to enrich the more conventional courses of study.
