The purpose of risk assessment is to support science-based decisions about how to solve complex societal problems. The problems we face in the twenty-first century have many social, political, and technical complexities. Environmental risk assessment in particular is of increasing importance as a means of seeking to address the potential effects of chemicals in the environment in both the developed and developing world.

The book is aimed at the next generation of risk assessors and students who need to know more about developing, conducting, and interpreting risk assessments. It delivers a comprehensive view of the field, complete with sufficient background to enable readers to probe for themselves the science underlying the key issues in environmental risk. Written in an engaging and lively style by a highly experienced risk assessment practitioner, the text: Introduces the science of risk assessment-past, present, and future Covers problem formation and the development of exposure factors Explains how human epidemiology and animal testing data are used to determine toxicity criteria Provides environmental sampling data for conducting practice risk assessments Examines the use of in vitro and 'omics methods for toxicity testing Describes the political and social aspects of science-based decisions in the twenty-first century Includes fully worked examples, case studies, discussion questions, and links to legislative hearings Readers of this volume will not only learn how to execute site-specific human health and ecological risk assessments but also gain a greater understanding of how science is used in deciding environmental regulations.
Like Marco Polo or Clare Francis, Ted Simon made a journey that millions dream of. He rode 63,000 miles, four years and fifty-four countries round the world. Spinning through the Sudanese desert, into prison in Brazil, into a Californian commune; through war, revolutions, disasters; into depths of fear, heights of euphoria and a fleeting love affair ... Riding the tightrope across vast continents, meeting their peoples, he is seen as a spy, as a glamorous, astonishing stranger and as a deity. And for Ted Simon, Magellan on a motorbike, it became a journey to the centre of his soul.
Simon rode a motorcycle around the world in the seventies, when such a thing was unheard of. In four years he covered 78,000 miles through 45 countries, living with peasants and presidents, in prisons and palaces, through wars and revolutions. What distinguishes this book is that Simon was already an accomplished writer. In 25 years this book has changed many lives, and inspired many to travel, including Ewan McGregor.
Ted Simon is the author of the classic travel book JUPITER'S TRAVELS. It documents his four-year journey round the world by motorbike, travelling through Europe, Africa, South and North America, and Asia. A number one bestseller in the late 1970s, it is still regarded as one of the greatest motorcycle books - indeed, one of the greatest travel books - ever written. In 2001, at the age of 69, Ted Simon decided to retrace his journey, and DREAMING OF JUPITER is the result. It took him two and a half years - during which time he revisited all the countries he had travelled through in the 1970s. He found much had changed, and he reflects upon the increased poverty, political upheavals, environmental issues and indeed the changes in himself. But ultimately, DREAMING OF JUPITER is a hugely inspiring read with a positive message at its heart - that even at the age of 70 you can still set off on an adventure, and be surprised and excited by what life throws at you along the way.
From the bestselling author of Jupiter's Travels and Dreaming of Jupiter comes an entertaining and inspiring new journey round Britain. Having crisscrossed the globe twice, Ted returns to the British Isles to rediscover the country of his youth. The result is a revealing portrait of modern Britain and a witty and affectionate journey back to the past, when Ted would hitchhike across the country visiting friends (and girlfriends). He returns to the site of his old school with its astonishing war time history and visits familiar haunts where he did his National Service and got his first job in newspapers. He also visits less-familiar places. Some inspire him (Winchester Cathedral). Others defeat him (a tax office in Nottingham). As he rolls through the Isles, he discovers that a great deal has changed: busier roads, bureaucracy and, worst of all, the dreaded 'Sat Nav'. But there is also much to celebrate and enjoy along the way. Packed with fascinating stories, extraordinary encounters and glorious depictions of the British countryside, Rolling through the Isles takes the reader on an unforgettable trip with a celebrated adventurer and writer.
A vivid chapter in the history of the California water wars, this book documents state and federal plans to flood the largest, most fertile valley in Mendocino County to send water south to Los Angeles. The eventual success of Richard Wilson, a rancher in Round Valley, to stop the project is the heart of this story. The book features an afterword by Robert Gottlieb and Ruth Langridge.
