The International Life Sciences Institute (ILSI) is a scientific foundation which addresses critical health and safety issues of national and international concern. ILSI promotes international cooperation by providing the mechanism for sci entists from government, industry and universities to work together on co operative programs to generate and disseminate scientific data. The members and trustees of the Institute believe that questions regarding health and safety are best resolved when scientists can examine and discuss issues, as an in dependent body, separate from the political pressures of individual countries and the economic concerns of individual companies. Frequently, meaningful assessment of the risk of a test substance is hindered by the inherent inconsistencies in the system. The development and refinement of methods and systems to evalute the safety of chemicals have evolved in a rapid and largely unplanned fashion. Attempts to improve the system have largely been directed toward broad general concerns, with little attention being given to specific problems or issues. A failure to resolve these problems has frequently resulted in increased testing costs and complications in the assessment and extrapolation of the results. In response to these difficulties, ILSI has assembled highly qualified and renowned scientists from research institutes, universities, government and in dustry, with relevant scientific knowledge and expertise regarding the issues that complicate risk assessment procedures.
The objective of a combined chronic toxicity/carcinogenicity study is to identify carcinogenic and the majority of chronic effects, and to determine dose-response relationships following prolonged and repeated exposure. The rat is typically used for ...
This guidance provides additional information on the conduct of studies performed using Test Guidelines 451, 452 and Test Guideline 453.
The objective of these chronic toxicity studies is to characterize the profile of a substance in a mammalian species (primarily rodents) following prolonged and repeated exposure. The Test Guideline focuses on rodents and oral administration. Both ...
These Guidance Notes outline core concepts in order to obviate the need to consult large numbers of text books, while still pointing the reader to sources of more detailed or specific information.
Wildlife Toxicity Assessments for Chemicals of Military Concern is a compendium of chemical-specific toxicity information with discussions on the rationale and development of Wildlife Toxicity Reference Values (TRVs) intended for use on terrestrial wildlife for risk assessment applications. Substances covered include military-related chemicals including explosives, propellants, pesticides and metals. Wildlife Toxicity Assessments for Chemicals of Military Concern is a much-needed resource designed to meet the needs of those seeking toxicological information for ecological risk assessment purposes. Each chapter targets a specific chemical and considers the current knowledge of the toxicological impacts of chemicals to terrestrial wildlife including mammalian, avian, amphibian and reptilian species. Provides detailed information on how Wildlife Toxicity Values (TRVs) for military chemicals of concern are derived and evaluated. Covers wildlife toxicity assessments of explosives, metals and environmental chemicals. Compiles relevant information on the environmental effects of chemicals on wildlife in relation to public and environmental health.
