Should the production and use of chlorine and all chlorinated organic compounds be halted, in view of their adverse effects on the environment and human health? Those in favour argue that certain chlorinated compounds (PCBs, DDT, CFCs, etc.) have large negative environmental effects. The use of chlorine in disinfectants leads to the production of chloroform, while bulk products (PVC) contribute to the production of chlorinated dibenzo-p-dioxins and dibenzofurans when they are burned. Those against argue that chlorine and many chlorinated compounds are essential in the control of human health (the prevention of disease transmitted through drinking water that has not been disinfected), and that chlorinated compounds are indispensable intermediates in many production processes, representing a vast economic value. But such discussions often ignore the fact that Nature contributes significantly to the production of chlorinated organic compounds. More than 1000 such compounds are known, and their contribution to the biogeochemical cycling of chlorine is underestimated. Chlorine is organically bound in large quantities to humic materials, and natural production mechanisms are known for low molecular weight compounds (methyl chloride, chloroform, chlorinated dibenzo-p-dioxins and dibenzofurans). The role of these compounds in the environment is largely unknown. Naturally-Produced Organohalogens gives a complete overview of the present state of knowledge on the subject, giving a much needed balance to the argument sketched out above.

Learning from Accidents (Hardcover, 3rd edition): Trevor Kletz Learning from Accidents (Hardcover, 3rd edition)
Trevor Kletz
R3,387 Discovery Miles 33 870 Ships in 10 - 15 working days

Review of previous edition:
"Trevor Kletz's book makes an invaluable contribution to the systematic, professional and scientific approach to accident investigation." The Chemical Engineer


Fully revised and updated, the third edition of Learning from Accidents provides more information on accident investigation, including coverage of accidents involving liquefied gases, building collapse and other incidents that have occurred because faults were invisible (e.g. underground pipelines).
By analysing accidents that have occurred Trevor Kletz shows how we can learn and thus be better able to prevent accidents happening again. Looking at a wide range of incidents, covering the process industries, nuclear industry and transportation, he analyses each accident in a practical and non-theoretical fashion and summarises each with a chain of events showing the prevention and mitigation which could have occurred at every stage.
At all times Learning from Accidents, 3rd Edition emphasises cause and prevention rather than human interest or cleaning up the mess. Anyone involved in accident investigation and reporting of whatever sort and all those who work in industry, whether in design, operations or loss prevention will find this book full of invaluable guidance and advice.
Completely up-dated.
Shows, by analysing accidents that have occurred, how we can learn from them, and prevent the same accidents happening again.

Introduction to Environmental Physics - Planet Earth, Life and Climate (Paperback): Peter Hughes, N.J. Mason Introduction to Environmental Physics - Planet Earth, Life and Climate (Paperback)
Peter Hughes, N.J. Mason
R2,688 Discovery Miles 26 880 Ships in 10 - 15 working days

The changing climate and its affect on all of us is becoming increasingly apparent - ozone depletion, hurricanes, floods and extreme weather behaviour. Introduction to Environmental Physics challenges the way we think about how and why environmental change occurs. This authoritative book aims to cover some of the more common and popular topics addressed in "physics of the earth", "physics of the environment" and "environmental physics" courses. It provides an essentially non- mathematical treatment suitable for a first year undergraduate level course. The principle topics covered are the physics of the built environment, the physics of human survival, energy for living, environmental health, revealing the planet, the sun and the atmosphere, the biosphere, the global climate and climate change. With contributions from well-respected experts on the subject, this textbook contains a summary, references and questions at the end of each chapter. This is an ideal textbook for first year undergraduates in a variety of courses, particularly physical geography, physics, environmental and earth science, with worked examples illustrating principles and vignettes from scientists who have made a significant contribution to the field enlightening the student along the way. As the authors say in the preface to this book, "At the outset of the 21st century there are many environmental challenges to be wrestled with, and though the environment is changing, the Physics is not!"

Human-Horse Relations and the Ethics of Knowing (Hardcover): Rosalie Jones McVey Human-Horse Relations and the Ethics of Knowing (Hardcover)
Rosalie Jones McVey
R3,725 Discovery Miles 37 250 Ships in 9 - 17 working days

This book explores how equestrians are highly invested in the idea of profound connection between horse and human and focuses on the ethical problem of knowing horses. In describing how ‘true’ connection with horses matters, Rosalie Jones McVey investigates what sort of thing comes to count as a ‘good relationship’ and how riders work to get there. Drawing on fieldwork in the British horse world, she illuminates the ways in which equestrian culture instils the idea that horse people should know their horses better. Using horsemanship as one exemplary instance where ‘truth’ holds ethical traction, the book demonstrates the importance of epistemology in late modern ethical life. It also raises the question of whether, and how, the concept of truth should matter to multispecies ethnographers in their ethnographic representations of animals.

We know certain chemicals cause problems in the workplace. The issues now are: Where do they occur in the workplace? How can we best evaluate them? What are the procedures for dealing with them safely? Many books simply define the problem and tell you that you need a program. Air Sampling and Industrial Hygiene gives you a guide to air sampling protocols from start to finish.
The book presents sampling technology updated with today's tools - such as microcircuitry and remote sensing. The authors emphasize an interdisciplinary approach to understanding how air monitoring can adequately report current environmental conditions associated with outdoor media, indoor remediation efforts, proximal equipment, interior line monitoring, and the interrelationship of ventilation parameters.
In addition to providing the how-tos of sampling, this guide covers the basics of chemical risk assessment, biological assessment, engineering evaluation of mechanical system design criteria, and chemical or process engineering hazard assessments. It presents the information using text, text outlines, graphics, and pictures - including cross sections of instrumentation and side bars to elaborate on complex concepts.
Faulty readings caused by poor sampling techniques can be very costly. This book provides the how-tos for making design engineering and on-site decisions as to instrumentation selection and scheduled usage. Air Sampling and Industrial Hygiene Engineering will allow you to complete the sampling process systematically and correctly from initial suspicions to the use of obtained results.

Environment and Development in the Straits of Malacca (Hardcover): Goh Kim Chuan, Mark Cleary Environment and Development in the Straits of Malacca (Hardcover)
Goh Kim Chuan, Mark Cleary
R1,166 Discovery Miles 11 660 Ships in 10 - 15 working days

The Straits of Malacca is one of the most important stretches of water in the world. Through its sea lanes have passed the ships of the major trading nations of the world. European colonialism from the 17th century onwards in the form of sailing ships gave it and the surrounding region significant geostrategic importance. Throughout the 20th century, the economic growth of South East Asia, built on trade and economic development, has continued to reinforce the importance of the Straits. This book is a study of the environment and development of the Straits. Taking an integrative approach, the book argues that the region has an underlying unity which political divisions (between Malaysia, Indonesia and Singapore) disguise. It emphasizes three major elements: first, the historical geography of the region highlights its role as a sea-corridor which both connected the markets of India and China. Secondly, contemporary patterns of economic development and trade have continued to build the importance of the region. Thirdly, major environmental problems now threaten the sea and the coast: from pollution to traffic to tourism.

R6,972 Discovery Miles 69 720 Ships in 10 - 15 working days

The 20th century's automobile-inspired land use changes brought about tremendous transformations in how stormwater moves across the modern urban land-scape. Streets and parking areas in the average urban family's neighborhood now exceed the amount of land devoted to living space. Add parking, office and commercial space, and it's easy to understand how modern cities have experienced a three-fold increase in impervious areas. Traditional wet weather collection systems removed stormwater from urban areas as quickly as possible, often transferring problems downstream. Innovative Urban WetWeather Flow Management Systems does two things: It considers the physical, chemical, and biological characteristics of urban runoff; then describes innovative methods for improving wet weather flow (WWF) management systems. The result of extensive research, Innovative Urban Wet-Weather Flow Manage-ment Systems looks most at how to handle runoff in developments of the 21st century: the confl icting objectives of providing drainage while decreasing stormwater pollutant discharges; the impact of urban WWF on surface and groundwater, such as smaller urban stream channels scoured by high peak flows; sediment transport and the toxic effects of WWF on aquatic organisms; the effectiveness of WWF controls-including design guidelines and source and downstream controls-are an important issue. Innovative Urban Wet-Weather Flow Management Systems looks at how source controls like biofi ltration, created through simple grading, may work in newly developing areas, while critical source areas like an auto service facilities, may need more extensive treatment strategies. Focusing WWF treatment on intensively used areas, such as the 20 percent of streets that handle the bulk of the traffic, and under utilized parking areas is also considered. Developing a more integrated water supply system-collecting, treating, and disposing of wastewater, and handling urban WWF-requires innovative methods, such as a neighborhood-scale system that would recycle treated wastewater and storm water for lawn watering and toilet flushing, or use treated roof runoff for potable purposes.
