CANMET's Environmental and Process Research on Uranium


Book Description

ABSTRACT: Tailings effluents cause major environmental problems for uranium mill tailings storage. Research is directed at rehabilitating pyritic tailings through revegetation and at reducing the overall radioactive load in the tailings through process innovation.




Strategic Science in the Public Interest


Book Description

The past twenty years have seen considerable shifts and struggles in government science that is, in the way the state funds, supports, regulates, conducts and uses scientific and technological activity. Focusing on federal labs and agencies, Strategic Science in the Public Interest explores how these labs have been located within, and often buried by, the larger commercially-focussed federal innovation agenda. G. Bruce Doern and Jeffrey S. Kinder examine four labs whose mandates deal with the Alberta oil sands, environmental technologies, wildlife research, and mining and metals, respectively. The authors use these cases to explain why a better middle-level approach to analysis is needed for strategic public interest-centred government science. They illustrate the importance of understanding the variety, as well as the similarity, of federal science and technology labs and agencies, and of instituting policies that reflect this diversity. The growing importance of Related Science Activities (RSA) is also explored, as well as the core trade-offs between commercial and public goods science in their mandates and their internal capacities.













Small-scale Freshwater Toxicity Investigations


Book Description

This broad review is the first to gather comprehensive information on the complete contemporary range of toxicity testing procedures and hazard assessment procedures, which is normally scattered and difficult to find. The two-volume set provides a consistent, template-based approach, linking relevant information on background, theory and practice to each bioassay. Volume 2 examines hazard assessment schemes. Includes extensive glossary.

Hard Rock Mine Reclamation


Book Description

Hard rock mines have significant effects on the territories where they operate, through both infrastructure construction as well as resource use. Due to their extractive activities, these mines store large quantities of wastes at the surface, which can be both physically and chemically unstable. Reclamation aims to return a mine site to a satisfactory state, meaning that the site should not threaten human health or security, should not generate in the long term any contaminant that could significantly affect the surrounding environment, and should be aesthetically acceptable to communities. This book focuses on the reclamation of waste storage areas, which constitute the main source of pollution during and after mine operations, and especially issues with acid mine drainage and neutral contaminated drainage. Features: Provides fundamental information and describes practical methods to reclaim mine-waste facilities Compares the different methods and illustrates their application at sites through case studies Identifies new reclamation issues and proposes solutions to address them Presents existing and new technologies to reclaim mine waste disposal areas from hard rock mines in different climatic conditions Integrates reclamation into mine operations and long term performance of techniques used through an interdisciplinary approach With mine site reclamation a young and still emerging science, the training needs for professionals and students working in this field are huge. This book is written from an engineering point of view and in it the authors identify new reclamation issues and propose well-tested as well as innovative approaches to addressing them. Students in graduate programs focused on mines and the environment as well as professionals already working in departments related to mine site reclamation will find this book to be a valuable and essential resource.




Concrete and Sustainability


Book Description

Concrete is by far the most common building material— accounting for twice the volume of all other such materials combined. With such a huge global economic impact, the industry has a correspondingly considerable responsibility to use it sustainably. Written by experts who pioneered research into environmental issues and concrete, Concrete and Sustainability examines the sustainability issues of the world’s main construction material and proposes attainable solutions. It provides a complete overview of the topic and tackles the complexity of the challenges from different angles. This book offers new data regarding the social and economic importance of concrete and proposes a discussion centered on a holistic approach in terms of resource availability, technical viability, economic feasibility, and environmental compatibility. The authors attribute a growing worldwide concern and understanding of sustainability issues, and an increased focus on climate change as the catalyst in this process. Instead of offering detailed technical advice or recommendations on sustainable issues, they provide examples showcasing sustainability efforts taking place in the concrete environment worldwide. The book includes examples and ideas for solutions from a large number of countries from across the globe. It presents a holistic and more complete overview of the emission and absorption topic, takes a look at the challenges from a combined old and new world viewing platform and offers an exploration of issues from a social and economic perspective. Concrete and Sustainability details the various rules and regulations that the industry is facing, discusses the various environmental challenges, and explores its impact. As emission, absorptions, and recycling have been the most central elements of discussion in the cement and concrete environment so far, these topics each receive their own chapters. This book also discusses other issues of concern within the various platforms in the industry, as well as future developments, and provides a comprehensive reference list.
