In 1973, 1975, and 1977 surveys of the doctorate-holding scientists and engineers in the United States were conducted by the National Research Council of the National Academy of Sciences. The science and engineering (S/E) population surveyed consisted of individuals who held S/E doctorates or who had received doctorates in non-S/E fields but were…

This book is one in a series developed to bridge the gap between the reasoning process and the language of mathematics. Chapter one of each volume discusses the theoretical concepts which are essential in understanding the calculations presented elsewhere in the book. This book's chapter 1 deals with basics such as fractions, decimals, ratios,…

This document reports the efforts of the AWWA Research Foundation to gather, prepare, and distribute current technical information in the wastewater reclamation and reuse field. The information reported has been abstracted from other Foundation publications and only attempts here to highlight the field. Categories discussed include research,…

This companion document to "Air Pollution Primer" is written for the nonexpert in air pollution; however, it does assume a familiarity with air pollution problems. This work is oriented toward providing the reader with knowledge about current and proposed air quality legislation and knowledge about available technology to meet these standards for…

This collection of articles emphasizes the need for care in the use of chemical pesticides. Economic and ecological implications of pest control are discussed, and data are given on the effectiveness and side effects of chemical insecticides. Alternative methods of control are proposed. The part that can be played by the public in decision making…

Discusses the procedure developed in Oregon to formulate a valid water quality index which accounts for the specific conditions in the water body of interest. Parameters selected include oxygen depletion, BOD, eutrophication, dissolved substances, health hazards, and physical characteristics. (CS)

This article presents in tabular form the air quality standards for sulfur dioxide, carbon monoxide, nitrogen dioxide, photochemicals, non-methane hydrocarbons and particulates for each of the 50 states and the District of Columbia. (CS)

Included are discussions surrounding organics in water that were presented at the water quality technology conference in 1978. Information is also provided on up-to-date water quality lab practices for disease control, heavy metal detection, and sodium monitoring. (CS)

Summarized are current analytical techniques used to classify, isolate, resolve, identify, and quantify organic compounds present in drinking water. A variety of methods are described, then drawbacks and advantages are listed, and research needs and future trends are noted. (CS)

This article is the third in a series summarizing existing treatment technology to meet the inorganic National Interim Primary Drinking Water Regulations. This report deals specifically with treatment methods for removing cadmium, lead, and silver from drinking water. (CS)

Briefly describes the current knowledge about the effects of environmental agents on man, and specifically outlines the action of a number of pollutants in the human body. Suggests guidelines for national and international action during the next decade to increase knowledge and understanding in this area. (JR)

Community Health and Environmental Surveillance System (CHESS), a nationwide program relating community health to environmental quality, is designed to evaluate existing environmental standards, obtain health intelligence for new standards, and document health benefits of air pollution control. (BL)

Explores problems and doubts regarding the extent to which air pollution must be reduced to eliminate further suffering and death. The adequacy of our present approach to air pollution control is evaluated together with an assessment of unknown factors affecting standards for a healthful environment. (BL)

Proposes seven rules to guide rational determination of permissible levels of air, water, and food contaminants to avoid unwarranted banning" and unreasonable economic and social costs. (AL)
