Impact of Pesticide Use on Health in Developing Countries Impact of pesticide use on health in developing countries Proceedings of a symposium held in Ottawa, Canada, 1 7-20 September 1990 IDRC CRDI International Development Research Centre Centre de recherches pour le devetoppement international 1 March 1993 Dear Reader/Librarian, IDRC is a public corporation created by the Canadian parliament in 1970 to help developing countries find viable solutions to their problems through research. At the 1992 Earth Summit, IDRC's mandate was broadened to emphasize sustainable development issues. As part of IDRC's strengthened commitment to global action and harüony, we are pleased to send you a complimentary copy of our most recent publication: The impact of pesticide use on health in developing countries (March 1993, 352 pages, 0-88936-560-1, $17.95). The first part of this book presents a brief survey of the global situation and the results of twelve epidemiological studies carried out by researchers from Africa, Latin America, Asia and the Middle East. These focus on poisonings resulting from organophosphates, herbicides, and pyrethroids. The second part illustrates the role of the process of development, production, spraying techniques and legislation in protecting the health of workers. A discussion of the benefits and modalities of access to pertinent information for the prevention of pesticide poisonings is provided in the third section. Finally, in the fourth section, consideration is given to the advantages and disadvantages of certain alternatives to the use of synthetic pesticides in agriculture and public health, such as botanical pesticides and integrated pest management strategies. We hope this book is a valuable addition to your collection. We would appreciate any comments you may have on this book.

Abstract The introduction of modern inputs, such as pesticides and chemicalfertilizers, has substantially increased agricultural productivity. Pesticides have also revolutionized the fight against endemic diseases in developing countries. Unfortunately, there is reverse side to this coin: the World Health Organization estimates that these agents cause 2 million cases of poisoning a year, of which 20 000 result in death. This book contains papers presented at a symposium to review the impact of pesticide use on health in developing countries. Part I presents a brief survey of the global situation and the results of 12 epidemiologic studies carried out by researchers in Africa, Asia, Latin America, and the Middle East. These focus on poisonings resulting from organophosphates, herbicides, and pyrethroids. Part II illustrates how the processes of development and production of pesticides, spraying techniques, and legislation can affect the health of workers. Part III consists of discussion of the benefits and ways of obtaining pertinent information for the prevention of pesticide poisonings. Finally, consideration is given to the advantages and disadvantages of certain alternatives to the use of synthetic pesticides in agriculture and public health, such as botanical pesticides and integrated pest management strategies. Résumé - C'est avec l'introduction des intrant modernes tels les pesticides et les engrais chimiques que l'agriculture a atteint son niveau de productivité actuel. De même, les pesticides ont révolutionné la lutte contre les grandes endérnies dans les pays en développement. Malheureusement, ii y a un revers a la médaille : l'Organisation mondiale de Ia santéestime a 2 millions par année les cas d'empoisonnement dus aces agents, dont 20000 sont mortels. Cette publication contient les communications présentees au colloque sur l'effet des pesticides sur Ia sante dans le tiers monde. La premiere partie donne un aperçu global de Ia situation et les constatations de douze etudes épidemiologiques faites par des chercheurs d'Afrique, d'Asie, d'Amérique latine et du Moyen-Orient. Ces etudes ant porte sur les empoisonnements dus aux organophosphates, aux herbicides et aux pyréthrinoides. La deuxième partie illustre comment la creation et Ia production des pesticides, les techniques de pulvérisation et la legislation peuvent influer sur la santédes travailleurs. La troisième partie traite des avantages que presente l'existence d'informations pertinentes sur les pesticides pour la prevention des empoisonnements et des modalités d'accès a ces inforrnations. La dernière partie porte sur les avantages et les inconvénients, en agriculture et en sante publique, de moyens de lutte autres que les pesticides synthetiques comme les pesticides d'origine vegétale et les strategies de defense integrées des cultures. Resumen - Gracias a la introducción de insumos modernos tales como pesticidas y fertilizantes qulmicos la agricultura ha aumentado notablemente su productividad. Los pesticidas han revolucionado a lucha contra las enfermedades endémicas en los palses en desarrollo, Lamentablernente, la medalla tiene tarnbién un reverso: La Organización Mundial de la Salud considera que estos agentes causan 2 millones de casos en envenenamiento por año, de los cuales 20 000 se traducen en muertes. En este libro se recogen las pan encias presentadas en un simposio organ izado para examinar el impacto del uso de pesticidas en la salud de los habitantes de los paises en desarrollo. La Parte I presenta un breve estudio de la situación global y los resultados de 12 estudios epidemiológicos realizados par investigadores en Africa, Asia, America Latina y en el Media Oriente. Estos se centran en envenenamientos causados par fosfatos orgdnicos, herbicidas y piretroides. La Parte II ilustra cómo Los procesos de desarrollo y producciOn de pesticidas, técnicas de rociado par aspersion, y la legislaciOn pue4en afectar la salud de los trabajadores. La Parte III del volu men examina los beneficios y modos de obtener Ia informacion pertinentes para Ia prevenciOn de envenenamientos par pesticidas. Finalmente, se consideran las ventajas y desventajas de ciertas alternativas hacia el usa tie pesticidas sintéticos tan to en agricultura coma en salud püblica, tales coino pesticidas botdnicos y estrategias integradas para control de plagas.

    Best Management Practices (BMPs) for Wildland Stewardship Protecting Wildlife When Using Herbicides for Invasive Plant Management California Invasive Plant Council & Pesticide Research Institute ontrolling invasive plants is often a high priority when protecting wildlife habitat, and those working to protect Cwildlife from invasive plants want to be sure their approach is safe for wildlife. This manual of Best Management Practices focuses on how land managers can best protect wildlife when using herbicides to control invasive plants. While any invasive plant control method can potentially impact wildlife, chemical control methods are the focus of this report. The toxicology information presented shows data on herbicides most commonly used for invasive plant management in California natural areas. The Best Management Practices are drawn from methods used by experienced land managers. Along with providing guidance for land managers, this document is designed to inform the interested public about how herbicides are used to control invasive plants in natural areas. ©2015 California Invasive Plant Council Available at www.cal-ipc.org Cite this report as: Cal-IPC. 2015.

    DESTRUCTION AND DECONTAMINATION TECHNOLOGIES FRO PCBs AND OTHER POPs WASTES UNDER THE BASEL CONVENTION A Training Manual for Hazardous Waste Project Managers Volume C - Annexes Secretariat of the Basel Convention Autoclaving Name of Process: Autoclaving Status: Autoclaving is a technology that has been around for many years now and is Applicable POPs wastes: well proven. In general for PCBs, only the oil and transformer components such PCB’s and not for other POPs as ceramics, cardboard and wood are incinerated. After decontamination, the various metals such as copper, steel and aluminium are sent to the metals recycling industry. In fact, the autoclaving cannot be compared with the other technologies dealt with, as it does not treat the PCB itself, but its objective is the clean-up and re- use of the with PCB contaminated materials, which is a completely different purpose as the other technologies. One has to consider that 98% of the contaminated oil is not going into the autoclaving but directly to the incinerator! Technology description: Autoclaving is a solvent decontamination process that extracts PCBs from contaminated material. The process is most often used in projects in conjunction with high temperature incineration. For capacitors the process involves shredding and placing all the material into the autoclaving chamber and by vacuum extraction with solvent remove the PCB. The condensers solid materials, after sawing and decontamination, are totally treated in the incineration plant through the solid burden way, and only the ceramics can then be landfilled. The extracted oil and PCBs is sent for HTI incineration, Alkali metal reduction or other alternative technologies.
