Data on water quality and other environmental issues are being collected at an ever-increasing rate. In the past, however, the techniques used by scientists to interpret this data have not progressed as quickly. This is a book of modern statistical methods for analysis of practical problems in water quality and water resources.The last fifteen years have seen major advances in the fields of exploratory data analysis (EDA) and robust statistical methods. The 'real-life' characteristics of environmental data tend to drive analysis towards the use of these methods. These advances are presented in a practical and relevant format. Alternate methods are compared, highlighting the strengths and weaknesses of each as applied to environmental data. Techniques for trend analysis and dealing with water below the detection limit are topics covered, which are of great interest to consultants in water-quality and hydrology, scientists in state, provincial and federal water resources, and geological survey agencies.The practising water resources scientist will find the worked examples using actual field data from case studies of environmental problems, of real value. Exercises at the end of each chapter enable the mechanics of the methodological process to be fully understood, with data sets included on diskette for easy use. The result is a book that is both up-to-date and immediately relevant to ongoing work in the environmental and water sciences.

The aim of this book is to summarize our understanding on the insect nicotinic acetylcholine receptors. This area of research received great impetus from the identification of the first subunit sequences to be used as neonicotinoid insecticide target sites. Although a book of this nature can provide the details only of commonly published results, it is hoped that it may provide a useful guide to the newcomer to the field as well as to point out some of the future challenges. For example, we need to determine the precise subunit nomenclature of insect nicotinic receptors. This nomenclature varies amongst species and this led to some of the early confusion that persists. We need to be precise in identifying the subunit composition of native insect nicotinic receptor subtypes, their functional properties and physiological roles.

This book brings together over 30 contributors with expertise in a variety of disciplines related to the topic. Although efforts continue toward reduction or elimination of pesticide chemicals in the management of pests in agriculture, public health and the urban arena, chemicals will continue to be one of the main weapons in control of insects, weeds, nematodes, plant diseases, etc. for some time to come. While considerable information is known about the acute toxicity of these compounds, information on the chronic effects from exposure to minute amounts of pesticide residues in food, water, air and soil is often very limited. This book approaches the topic from several different vantage points including pesticide epidemiology, new modes of action to minimize nontarget exposure, bioremediation of contaminated areas, molecular biology of the modes of action and detoxication of pesticides, and the dynamics of pesticide movement in the environment. As world leaders in the manufacture and use of pesticides, countries must cooperate in the search for safer pesticides with minimum chronic effects on humans and the environment. This book helps to remove the barriers of distance and language and should lead to new cooperative research efforts across country lines and discipline lines.

Praise for the First Edition " . . . an excellent addition to an upper-level undergraduate course on environmental statistics, and . . . a 'must-have' desk reference for environmental practitioners dealing with censored datasets." —Vadose Zone Journal Statistics for Censored Environmental Data Using Minitab® and R, Second Edition introduces and explains methods for analyzing and interpreting censored data in the environmental sciences. Adapting survival analysis techniques from other fields, the book translates well-established methods from other disciplines into new solutions for environmental studies. This new edition applies methods of survival analysis, including methods for interval-censored data to the interpretation of low-level contaminants in environmental sciences and occupational health. Now incorporating the freely available R software as well as Minitab® into the discussed analyses, the book features newly developed and updated material including: A new chapter on multivariate methods for censored data Use of interval-censored methods for treating true nondetects as lower than and separate from values between the detection and quantitation limits ("remarked data") A section on summing data with nondetects A newly written introduction that discusses invasive data, showing why substitution methods fail Expanded coverage of graphical methods for censored data The author writes in a style that focuses on applications rather than derivations, with chapters organized by key objectives such as computing intervals, comparing groups, and correlation. Examples accompany each procedure, utilizing real-world data that can be analyzed using the Minitab® and R software macros available on the book's related website, and extensive references direct readers to authoritative literature from the environmental sciences. Statistics for Censored Environmental Data Using Minitab® and R, Second Edition is an excellent book for courses on environmental statistics at the upper-undergraduate and graduate levels. The book also serves as a valuable reference for??environmental professionals, biologists, and ecologists who focus on the water sciences, air quality, and soil science.

This book, which is the result of contributions from a team of international authors, presents a collection of materials that can be categorized into two groups. The first group of papers deals with clinical toxicology topics including poisoning by anticoagulant rodenticides, food toxins, carbon monoxide, the toxicity of beta-lactam antibiotics, acute neonicotinoid poisoning, occupational risk factors for acute pesticide poisoning, activating carbon fibers, and date pits for use in liver toxin adsorption. The second group of papers deals with forensic or analytical toxicology topics such as simplified methods for the analysis of gaseous toxic agents, rapid methods for the analysis and monitoring of pathogens in drinking water and water-based solutions, as well as the linkages between clinical and forensic toxicology. Each chapter presents new information on the topic discussed based on authors' experience while summarizing existing knowledge. As such, this book will be a good teaching aid and can be a prescribed or recommended reading for postgraduate students and professionals in the fields of public health, medicine, pharmacy, nursing, biology, toxicology, and forensic sciences.

This edited book, Toxicity and Hazard of Agrochemicals, is intended to provide an overview of toxicology that examines the hazardous effects of common agrochemicals employed every day in our agricultural practices. Furthermore, it is hoped that the information in the present book will be of value to those directly engaged in the handling and use of agrochemicals and that this book will continue to meet the expectations and needs of all interested in the different aspects of human and environmental risk toxicities.
