« This report is a compilation and analysis of the results of nearly 10 years of testing the lethal dietary toxicities of pesticidal and industrial chemicals to young bobwhites (Colinus virginianus), Japanese quail (Coturnix c. japonica), ring-necked pheasants (Phasianus colchicus), and mallards (Anas platyrhynchos). A total of 131 compounds were tested. » --

This report presents measurements of the lethal dietary toxicity of 89 pesticidal chemicals to young bobwhites, Japanes quail, ring-necked pheasants, and mallards. Toxicity is expressed as the median lethal concentration (LC50) of active chemical in a 5-day ad libitum diet. LC50's and associated statistics are derived by methods of probit analysis. Endrin consistently was the most toxic chemical while aldrin and dieldrin were among the six most toxic chemicals of those tested on all species. In general, organophosphates were less toxic than aldrin or dieldrin, and herbicides were of a low order of toxicity. There were obvious inconsistencies in the relative sensitivity of the four species to various chemicals.

Discussing the interpretation of tissue concentrations of contaminants in wildlife, this updated edition of a bestseller draws on current scientific research and includes new chapters and greater emphasis on aquatic organisms. Each chapter provides a summary and review of a specific chemical along with direction on research methods and the interpretation of conflicting or insufficient data. Chapters include a comprehensive history of contaminant interpretation in wildlife and fish, the use of tissue residues in ecological risk assessment, and detailed coverage of all bioaccumulative contaminants and their physiologic affects.

The Toxic Substances Control Act (PL 94-469) directs the U.S. Environmental Protection Agency (EPA) to produce standards for the development of adequate data regarding the effect of chemical substances and mixtures on health and the environment. The agency is developing test standards to satisfy this charge. This paper describes part of the process by which a test standard is developed, using the avian dietary median lethal concentration (LC50) toxicity test as an example. The history of avian dietary toxicity test methods is briefly described, along with the kinds of modifications in methods made by various users. The rationale for the selection of specific test conditions and procedures is discussed with respect to the use of the test results by a regulatory agency. Selection criteria for several controversial test parameters are presented as examples.

Basic Environmental Toxicology provides a thorough, systematic introduction to environmental toxicology and addresses many of the effects of pollutants on humans, animals, and the environment. Readers are introduced to the fundamentals of toxicology and ecotoxicology, the effects of different types of toxicants, and how toxicants affect different compartments of the environment. Fundamental aspects of environmental health, occupational health, detection of pollutants, and risk assessment are discussed. The book is excellent for anyone involved in risk assessment or risk management, toxicologists, state and local public health officials, environmental engineers, industrial managers, consultants, and students taking environmental toxicology courses.
