Methods Of Pesticide Exposure Assessment

This book is a summary of the presentations and discussions at the Workshop on Methods of Pesticide Exposure Assessment held in Ottawa, Canada, on October 5-8, 1993. The event was a joint effort of Health Canada and the North Atlantic Treaty Organisation and was officially supported by the United States Environmental Agency and the Organisation for Economic Co-operation and Development (OECD). The goal of the workshop was to examine current issues in the field of pesticide exposure assessment with the aim of reaching an internationally harmonized approach to methods of exposure assessment. With regulatory agencies of OECD Member countries moving towards the harmonization of data requirements, it was timely and beneficial to bring together international experts in the field of pesticide exposure assessment to discuss current issues. Approximately 60 delegates and 20 observers participated, including individuals from 15 different countries representing academia, government, industry and international organizations. A guidance document on methods of pesticide exposure assessment was presented as a means to achieving the goal of international for critique and discussion harmonization. After extensive discussion, the workshop delegates agreed in principle to procedures for revising the guidance document. Following revision and further review by a designated peer review group, the revised document will be submitted to the OECD for consideration as a draft OECD Guidance Document on pesticide exposure assessment methods. Both the revised and original documents are included in these proceedings.

This timely publication concentrates on the exposure to pesticides by agricultural workers and residential users of pesticides through inhalation and physical contact. The book discusses more recently discovered risks such as pesticides on indoor carpets and includes new trends in data interpretation. Occupational & Residential Exposure Assessment for Pesticides complements the other title on pesticide exposure in the series - Pesticide Residues in Drinking Water, by Hamilton/Crossley and is a must for all professionals in the Pesticide Industry as well as academics.

Exposure and Risk Assessment of Pesticide Use in Agriculture: Approaches, Tools and Advances offers an overview of the different methods available in toxicology for pesticide exposure and risk assessment, ranging from the regulatory field, to in-field research studies. The book provides technical background on each method, describing known and grounded tools, new uses of tools and development prospects. This book is ideal for researchers in pesticide toxicology, exposure toxicology, toxicologic risk assessment, occupational hygiene and medicine, and pesticide toxicology as well as occupational health and industrial hygiene practitioners, regulatory experts of corporate and public bodies, and advanced students. Covers pesticide exposure and risk assessment, ranging from fundamentals to advanced theory Explains methods that are useful for both experts and non-experts Details the use of each method for exposure and risk assessment, also including links to additional resources and further reading

Based on discussions at the 2007 SETAC Europe PERAS Workshop in Coimbra, Semi-Field Methods for the Environmental Risk Assessment of Pesticides in Soil presents a timely summary of state-of-the-art higher-tier terrestrial risk assessment of plant protection products (PPPs). Influential regulators, academics, and industry scientists provide a compre

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.

Methods for determining exposure of pesticides to agricultural workers have been developing for over thirty years. You may ask: what more do we need to know? Worker Exposure to Agrochemicals provides the answer. It contains a compilation of research papers that examine this issue from every angle. Even with all the information available, there still remains an intense debate over what method - dermal deposition or biological monitoring - provides better results when measuring worker exposure. Researchers almost never realize the same results in concurrent experiments using both methods. The question is: which process is more accurate? Worker Exposure to Agrochemicals examines the effectiveness of both procedures. Two chapters describe the simultaneous use of both methods and their outcome. The remaining chapters cover risk assessment, protective clothing, Canadian dosimetry, "Jazzercise," a tiered approach to exposure estimation, modeling reentry exposure, performing a dislodgeable residue study, and GLP requirements.
