In this paper, we compared the levels of awareness, knowledge and attitudes (AKA) about environmental pollution of secondary school students from two South African provinces. The purpose was to determine the levels of AKA between students living under different environmental conditions. These two groups were students from a coal-mining province…

As one reads about the history of humans, he/she sees very early on that humans are naturally "tool users." More specifically, humans used tools as a means of subsistence and survival. Even today humans use tools to extend their capabilities beyond imagination. These tools are even used as weapons. However primitive, these early weapons would soon…

This paper is part of an extensive study of secondary school students' preconceived ideas about climate change. Here, we undertake a survey in the province of Valencia (Spain) to ascertain secondary school students' notions of the causes and consequences of climate change. Results show, among other things, that students clearly relate the misuse…

This article is a brief overview of the energy problems of today and of the future. Energy sources, factors contributing to fossil fuel shortage, energy conservation, energy demands and uses in the United States, and the advantages and disadvantages of alternative fuels are discussed. (TK)

Air pollution control authorities were forced to relax air quality standards during the winter of 1972 by granting variances. This paper examines the institutional characteristics of these variance policies from an economic incentive standpoint, sets up desirable structural criteria for institutional design and arrives at policy guidelines for…

Redevelopment and expansion of United States coal resources are economic necessities. Environmentalists' objections to the less expensive, available United States coal, that introduces large amounts of SOx and particulates into the air, may be overcome with the options of coal cleaning, tall stacks, material recovery and stack cleaning. (BT)

Although atmospheric pollution can be reduced or eliminated in many different ways, each way involves questions of economics, the time factor, availability of materials, priority over other urgent reforms, and individual and social psychology. To provide a basis for consideration of these questions, this book gives information not only about the…

This instructor's manual provides lesson plans for the teaching of a course in combustion evaluation in control of air pollution. It includes: (1) an introduction, (2) goals, (3) instructional objectives, (4) course background, (5) course agenda, (6) prerequisite skills, (7) intended student population, (8) course presentation, (9) texts and…

This student manual supplements a course designed to present fundamental and applied aspects of combustion technology which influence air pollutant emissions. Emphasis is placed on process control of combustion rather than on gas cleaning. The course is intended to provide engineers, regulatory and technical personnel, and others with familiarity…

Presented are exercises intended to supplement course work in air pollution control, specifically as they relate to combustion. Chapters offered in this workbook include: (1) Combustion Calculations, (2) Combustion System Design Problems, (3) Emission Calculations I, (4) Emission Calculations II, (5) Afterburner Design Problems, and (6) Cumbustion…

Explains the operation of the Magnetohydrodynamic (MHD) generator and advantages of the system over coal, oil or nuclear powered generators. Details the development of MHD generators in the United States and Soviet Union. (CP)

Describes the operational principles of magneto hydro dynamic generators and considers environmental advantages of their use. (AL)

Supports the development of nuclear power plants and considers some problems and possible solutions: future power needs, power costs, thermal pollution, radionuclide discharge. Describes advantages and applications of dual purpose power plants for purifying water, producing phosphorus and ammonia, and serving as fast breeder reactors for Pu 239.…
