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.

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.

Pesticide Chemistry: Human Welfare and the Environment, Volume 3: Mode of Action, Metabolism and Toxicology covers the proceeding of the Fifth International Congress of Pesticide Chemistry. This book is organized into three parts that tackle relevant issues regarding the use of pesticide. The opening part tackles topics relevant to the biochemistry of pests and mode of action of pesticides, such as influence of chlorinated and parathyroid insecticide on cellular calcium regulatory mechanisms; behavioral and lethal actions of amidines on invertebrates; and insect chitin synthetase as biochemical probe for insecticidal compounds. The second part encompasses metabolism and degradation of pesticides and xenobiotics and includes topics on propesticides; selective toxicity conferred by activation; and comparative biochemistry of animal, plant, and microorganism oxidases. The last part covers the toxicology of pesticides and xenobiotics, including the role of biochemical studies in modern toxicological assessment of pesticides; neurophysiological and behavioral assessment of pesticide toxicity; and genetic toxicology applied to the assessment of mutagenic, carcinogenic, and teratogenic action of pesticides and related compounds. This book will be of great interest to chemists, biologists, botanists, and entomologists or professionals whose line of work involves the use of pesticides and who are concerned with pesticide side-effects to the users and the environment.

Pesticide control involves killing pest organisms or otherwise preventing them from destructive behavior. Pesticides are either natural or synthetic and are applied to target pests in a myriad of formulations (EC,WP, SP, FP, G etc.) and application technology systems (sprays, baits, slow-release diffusion, dust, etc.). In recent years, the bacterial genes coding for insecticidal proteins have been incorporated into various crops that dealt with the mortality of the pests feeding on them. Many other eco-friendly methods for insect pest control such as Integrated Pest Management (IPM), use of bio-pesticides etc., are becoming popular. Bio-pesticides and IPM should show good growth in the future, as there is growing concern for the eco-friendly organic agriculture and could be achieved through Good Agriculture Practices (GAP). Use of pesticides requires a proper understanding of the chemistry, their handling and their use in crop protection or hygiene. These are toxic chemicals and require a good understanding of therapy and antidotes at the time of poisoning. This e-book covers pesticide chemistry, metabolic/degradation pathways, biochemical toxicology, therapy and antidotes, nano-pesticides and terminologies associated with pesticide toxicology. the book should serve as a text book for academia, or as a reference work for agriculturists, environmentalists and industry professionals.

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.
