First Published in 1991, this book conducts a systematic analysis of existing information regarding the toxicological effects of pesticides on humans. The book identifies the negative health effects related to exposure to pesticides and the biological changes required to undertake biological monitoring. The book also discusses the importance and magnitude of the problem for different kinds of pesticide applications in different parts of the world, explains the toxicodynamics and clinical picture of acute and chronic intoxications resulting from exposure to different groups of pesticides and selected individual substances, and evaluates existing methods and limitations for assessing human exposure to pesticides. Pesticide manufacturers, occupational health professionals, epidemiologists, environmentalists, government agencies and others concerned with the effects of pesticides on human populations should consider this book essential reading.

Many of the pesticides applied to food crops in this country are present in foods and may pose risks to human health. Current regulations are intended to protect the health of the general population by controlling pesticide use. This book explores whether the present regulatory approaches adequately protect infants and children, who may differ from adults in susceptibility and in dietary exposures to pesticide residues. The committee focuses on four major areas: Susceptibility: Are children more susceptible or less susceptible than adults to the effects of dietary exposure to pesticides? Exposure: What foods do infants and children eat, and which pesticides and how much of them are present in those foods? Is the current information on consumption and residues adequate to estimate exposure? Toxicity: Are toxicity tests in laboratory animals adequate to predict toxicity in human infants and children? Do the extent and type of toxicity of some chemicals vary by species and by age? Assessing risk: How is dietary exposure to pesticide residues associated with response? How can laboratory data on lifetime exposures of animals be used to derive meaningful estimates of risk to children? Does risk accumulate more rapidly during the early years of life? This book will be of interest to policymakers, administrators of research in the public and private sectors, toxicologists, pediatricians and other health professionals, and the pesticide industry.

This detailed volume explores practical procedures on the identification and quantification of pesticides in a variety of samples. Chapters guide the reader through methods and protocols for the extraction of pesticides from biological and non-biological samples, pitfalls in dosing techniques and structures identification, and also provide an overview of the problems that these pesticides cause in human populations. As part of the Methods in Pharmacology and Toxicology series, chapters include introductions to their respective topics, lists of reagents and materials, step-by-step guides and reproducible lab protocols, as well as valuable tips on addressing common problems and avoiding known pitfalls. Authoritative and practical, Pesticide Toxicology is an ideal reference for academia, analysts, toxicologists, environmentalists, and health and industry professionals aiming to understand the associated risks and to limit the use of these substances and minimize their potential damage to human health and the environment.

The EPA commissioned The National Academies to provide advice on the vexing question of whether and, if so, under what circumstances EPA should accept and consider intentional human dosing studies conducted by companies or other sources outside the agency (so-called third parties) to gather evidence relating to the risks of a chemical or the conditions under which exposure to it could be judged safe. This report recommends that such studies be conducted and used for regulatory purposes only if all of several strict conditions are met, including the following: The study is necessary and scientifically valid, meaning that it addresses an important regulatory question that can't be answered with animal studies or nondosing human studies; The societal benefits of the study outweigh any anticipated risks to participants. At no time, even when benefits beyond improved regulation exist, can a human dosing study be justified that is anticipated to cause lasting harm to study participants; and All recognized ethical standards and procedures for protecting the interests of study participants are observed. In addition, EPA should establish a Human Studies Review Board (HSRB) to evaluate all human dosing studiesâ€"both at the beginning and upon completion of the experimentsâ€"if they are carried out with the intent of affecting the agency's policy-making.

The impetus for this book came from numerous requests by public and private agencies and citizens for information regarding the human health effects of pes ticide exposures. We have tried to compile a relatively complete, concise sum mary of the acute and chronic health effects and the toxicology of pesticides in a format that provides quick and easy access. This book was written to address the needs of the following groups: medical and public health professionals, tox icologists, environmentalists, industrial hygienists, regulators, producers and users of pesticides, public interest advocates, and the legal profession. Acknowledgments We are indebted to Mr. Christopher J. Wiant, Chief of the Environmental Chemistry Section of the Illinois Department of Public Health. The financial support provided by his office was essential in producing this book. We are also indebted to Dr. Charles Benbrook, former staff member, and Representative George E. Brown, Chairman of the Subcommittee on Depart ment Operations, Research and Foreign Agriculture of the Committee on Agri culture, United States House of Representatives, for their guidance in obtain ing pesticide toxicity data. In the Freedom of Information Office, Office of Pesticide Programs of the United States Environmental Protection Agency, the patience and assistance of Therese Murtagh and Virginia Salzman in obtaining documents are appreciated. Of the numerous individuals who participated in the production of this book, the following merit special recognition for the quality of their research, editing, and critical skills: Mark Loafman, Sue Ramirez, Steve Smith, Sally Burns, and Denise Steurer.

In this important reference work, Zeliger catalogs the known effects of chemical mixtures on the human body and also proposes a framework for understanding and predicting their actions in terms of lipophile (fat soluble) / hydrophile (water soluble) interactions. The author's focus is on illnesses that ensue following exposures to mixtures of chemicals that cannot be attributed to any one component of the mixture. In the first part the mechanisms of chemical absorption at a molecular and macromolecular level are explained, as well as the body's methods of defending itself against xenobiotic intrusion. Part II examines the sources of the chemicals discusssed, looking at air and water pollution, food additives, pharmaceuticals, etc. Part III, which includes numerous case studies, examines specific effects of particular mixtures on particular body systems and organs and presents a theoretical framework for predicting what the effects of uncharacterized mixtures might be. Part IV covers regulatory requirements and the need to adjust recommended exposure levels for products containing mixtures. It also contains recommendations on how to limit exposure to mixtures in the products we use and on how to limit release of mixtures into the environment. Providing brief summaries of each mixture and its effects, Zeliger provides a comprehensive reference, a jumping off point for professionals (with extensive chapter bibliographies) and an introduction to the topic for those studying traditional toxicology. Addressing many inadequately understood illnesses and conditions such as asthma, infertility and cancer, it will also be of interest to health professionals, environmental scientists and lawyers. - Presents a theoretical framework for predicting the effects of chemical mixtures for which no specific data exists (this predictive aspect is important due to the vast number of different potential chemical combinations – far too many to comprehensively catalog) - A quick and convenient source of hard to come by data on the rapidly developing field of chemical mixtures, for groups including chemists and engineers, toxicologists, health professionals and environmental scientists - New and updated material comprises over 30% of this timely new edition, which includes the latest research data alongside an expanded introduction to the science and art of predicting the toxicological properties of chemical mixtures

Hayes, Jr., co-Editor of the first edition. - Presents a comprehensive look at all aspects of pesticide toxicology in one reference work. - Clear exposition of hazard identification and dose response relationships in each chapter featuring pesticide agents and actions - All major classes of pesticide considered - Different routes of exposure critically evaluated

This volume of the IARC Monographs provides evaluations of the carcinogenicity of some organophosphate insecticides and herbicides, including diazinon, glyphosate, malathion, parathion, and tetrachlorvinphos. Diazinon acts on a wide range of insects on crops, gardens, livestock, and pets, but most uses have been restricted in the USA, Canada, and the European Union since the 1980s. Glyphosate is the most heavily used agricultural and residential herbicide in the world, and has been detected in soil, air, surface water, and groundwater, as well as in food. Malathion is one of the oldest and most widely used organophosphate insecticides, and has a broad spectrum of applications in agriculture and public health, notably mosquito control. The insecticide parathion has been largely banned or restricted throughout the world due to toxicity to wildlife and humans. Tetrachlorvinphos is banned in the European Union, but continues to be used in the USA and elsewhere as an insecticide on animals, including in pet flea collars. The IARC Monographs Working Group reviewed epidemiological evidence, animal bioassays, and mechanistic and other relevant data to reach conclusions as to the carcinogenic hazard to humans of these agents.

Environmental Toxicology of Pesticides provides an overview of the state of knowledge in the major pesticidal subject areas and describes the efforts and approaches underway in solving or understanding these problems. The book emerged from the United States-Japan seminar on ""Environmental Toxicology of Pesticides"" held in Oiso, Japan, in October 1971. The purpose of the seminar was to discuss and exchange ideas and technology on the problems associated with pesticidal contamination in these two countries. The book is organized into eight parts. Part I reviews pesticide use and contamination levels in Japan, the United States, and Britain. Part II examines the environmental impact of mercury. Part III presents studies on chlorinated hydrocarbon pesticides. Part IV examines the effects of fungicides, herbicides, organophosphates, and carbamates. Part V deals with the microbial degradation of pesticides. Part VI examines the photodecomposition of pesticides. Part VII investigates the biological effects of pesticides on wildlife. Part VIII deals with the development of new pesticides.
