The mixing-layer height and the average wind speed within the mixing layer were calculated twice for each day of a 5-year record of upper air observations at 62 National Weather Service stations int he contiguous United States. The times of day of these calculations are morning and mid-afternoon. A rough allowance was made for effects of the urban "heat island" on the morning mixing heights. The morning and afternoon times coincide approximately with those of maximum and secondary minimum concentrations of slow-reacting pollutants in cities. These calculations illustrate the typical large diurnal variation in atmospheric dispersion. Twenty charts present seasonal and annual, and morning and afternoon mean mixing heights and wind speeds. A model of some general dispersion features over urban areas is described in which the normalized pollutant concentration averaged over a city is a function of mixing height, wind speed, and city size (distance the wind travels across the city). Frequency values of mixing height by wind speed are used with the model to calculate average normalized concentration frequencies for each weather station. Thirty charts present isopleth analyses of seasonal and annual, and morning and afternoon normalized pollutant concentrations that were exceeded 10, 25, and 50 percent of the time for specified city sizes. The occurrence of episodes during which upper limits on mixing height and wind speed were not exceeded were determined from the daily morning and afternoon values of these parameters. Isopleths of the total number of episode-days for episodes lasting at least 2 days and at least 5 days with various limiting mixing-height and wind-speed values are presented in 20 charts.

This CRCnetBASE version of the best-selling Environmental Engineers' Handbook contains all of the revised, expanded, and updated information of the second edition and more. The fully searchable CD-ROM offers virtually instant access to all of the interrelated factors and principles affecting our environment as well as how the government and the industry must deal with it. It addresses the ongoing global transition in cleaning up the remains of abandoned technology, the prevention of pollution created by existing technology. The Environmental Engineers' Handbook on CD-ROM provides daily problem solving tools and information on state-of-the-art technologies for the future. The technology and specific equipment used in environmental control and clean-up is included for those professionals in need of detailed technical information. Because analytical results are an essential part of any environmental study, analytical methods used in environmental analysis are presented as well. Data is clearly presented in tables and schematic diagrams that illustrate the technology and techniques used in different areas. Béla G. Lipták speaks on Post-Oil Energy Technology on the AT&T Tech Channel.

Proceedings of the Second International Clean Air Congress documents the information and experiences exchanged at the Second International Clean Air Congress held in Washington, D.C. on December 6-11, 1970. This book compiles technical papers of five representatives from the national non-governmental air pollution prevention association of Argentina, France, West Germany, Japan, and the United Kingdom that aims to determine how they might work together cooperatively to contribute to the conservation of the world's air resources The topics discussed include the Swedish experiences on sensory evaluation of odorous air pollutant intensities; chronic fluoride intoxication due to air pollution; and organic ozone reactions as singlet oxygen sources. The emission and control of air pollutants from the incineration of municipal solid wastes and gaseous plume diffusion about isolated structures of simple geometry are also covered. This publication is a good reference for environmentalists and students interested in the scientific, technological, and administrative aspects of air pollution control.
