Freshwater field tests are an integral part of the process of hazard assessment of pesticides and other chemicals in the environment. This book brings together international experts on microcosms and mesocosms for a critical appraisal of theory and practice on the subject of freshwater field tests for hazard assessment. It is an authoritative and comprehensive summary of knowledge about freshwater field tests, with particular emphasis on their optimization for scientific and regulatory purposes. This valuable reference covers both lotic and lentic outdoor systems and addresses the choice of endpoints and test methodology. Instructive case histories show how to extrapolate test results to the real world.

Examine the Current State of the Science Surface water sampling programs across the globe have shown the presence of many different classes of medicines. The potential risks associated with the release of these medicines into the environment have become an increasingly important issue for environmental regulators. Effects of Veterinary Medicines in the Environment examines the current state of the science in evaluating the potential risks of veterinary medicines to aquatic and terrestrial ecosystems. International Panel Provide Guidance The book brings together more than 30 experts, from eight countries, with expertise in risk assessment, environmental toxicology and chemistry, and environmental policy and regulation. These experts provide guidance, based on standard risk assessment approaches, on how to assess the environmental effects of veterinary medicines. The text discusses pathways to the environment, exposure and effects assessment, and risk assessment and management in terrestrial and aquatic environments. It reviews classes of veterinary medicines and current regulations, identifies the environmental fate of the medicines, and assesses the use of read-across, QSAR, and other modeling approaches. Detailed Coverage of Technical Approaches An examination of the current state of the science, the book provides integrated content in a single source. It provides detailed coverage of technical approaches that helps practitioners better understand the environmental risks of veterinary medicines.

Why make a joke out of a niche and complex scientific problem? That is the question at the heart of this book, which unearths the rich and surprising history of trying to find longitude at sea in the eighteenth century. Not simply a history on water, this is the story of longitude on paper, of the discussions, satires, diagrams, engravings, novels, plays, poems and social anxieties that shaped how people understood longitude in William Hogarth’s London. We start from a figure in one of Hogarth’s prints – a lunatic incarcerated in the madhouse of A Rake’s Progress in 1735 – to unpick the visual, mental and social concerns which entwined around the national concern to find a solution to longitude. Why does longitude appear in novels, smutty stories, political critiques, copyright cases, religious tracts and dictionaries as much as in government papers? This sheds new light on the first government scientific funding body – the Board of Longitude – established to administer vast reward money for anyone who found a means of accurately measuring longitude at sea. Meet the cast of characters involved in the search for longitude, from famous novelists and artists to almost unknown pamphleteers and inventors, and see how their interactions informed the fate of longitude’s most famous pursuer, the clockmaker John Harrison.
