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.

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.

"In a recent survey of 820 Boro (winter rice), potato, bean, eggplant, cabbage, sugarcane, and mango farmers in Bangladesh, over 47 percent of farmers were found to be overusing pesticides. With only 4 percent of farmers formally trained in pesticide use or handling, and over 87 percent openly admitting to using little or no protective measures while applying pesticides, overuse is potentially a threatening problem to farmer health as well as the environment. To model pesticide overuse, the authors used a 3-equation, trivariate probit framework, with health effects and misperception of pesticide risk as endogenous dummy variables. Health effects (the first equation) were found to be strictly a function of the amount of pesticides used in production, while misperception of pesticide risk (the second equation) was determined by health impairments from pesticides and the toxicity of chemicals used. Pesticide overuse (the third equation) was significantly determined by variation in income, farm ownership, the toxicity of chemicals used, crop composition, and geographical location. The results highlight the necessity for policymakers to design effective and targeted outreach programs that deal specifically with pesticide risk, safe handling, and averting behavior. Ideally, the approach would be participatory in nature to address key informational gaps, as well as increasing a farmers' awareness retention. The results also point to specific crops and locations experiencing a higher prevalence of overuse-bean and eggplant in general-and overall production in the districts of Chapainawabganj, Chittagong, Comilla, Jessore, Narshingdi, Rajshahi, and Rangpur. Focusing efforts in these crop and geographical areas may have the most measurable effects on pesticide overuse. "--World Bank web site.

This book, originally published in 1992, describes the Soviet environment at its crisis point in the late 1980s and early 1990s. Beolorussia and the Ukraine had, as a result of the Chernobyl accident, been declared ecological disaster zones and across the country as a whole as many as 20 per cent of the population lived in environmental danger areas and another 35-40 per cent in unsatisfactory conditions. According to a Supreme Soviet Environment Committee report of 1989, 80% of all illness in the USSR related either directly or indirectly to environmental problems. In this book, leading specialists from both the West and the Soviet Union present a comprehensive analysis of these problems. The contributors examine the aftermath of Chernobyl, the catastrophic causes and effects of the Aral Sea's shrinkage, the environmental issues and public unrest. The depth of analysis in this volume together with the breadth of topics addressed will ensure that it is read by students and specialists of the Soviet Union and environmental issues, as well as by all government officials, journalists and industrialists with an interest in the Soviet environment.
