Advances in the theory and modelling of pollutant-gas washout

Description: A program for evaluation of precipitation scavenging as a mechanism of removal of contaminants from power plant plumes has been in progress. This program began with field studies at the Keystone plant in Western Pennsylvania, which led to the development of new gas-washout models and related field studies at other locations. The progress of this program is described and some comparisons of measured SO/sub 2/ washout concentrations with those predicted by reversible and irreversible gas washout … more

Handbook of air pollutant emissions from transportation systems

Description: Procedures for estimating the rate of air pollutant emissions from transportation systems are described. Emission factors and computation techniques for motor vehicles, railroad locomotives, aircraft, and waterborne vessels are presented. The major emphasis is on motor vehicle emission computations and data on model year emission rates, control device deterioration, and vehicle speed adjustments are given. Procedures for separating the cold start, computing evaporative emissions by source, and … more

Aerial radiological measuring survey of the area surrounding the Enrico Fermi Atomic Power Plant, Monroe, Michigan, September 1970

Description: The Aerial Radiological Measuring System (ARMS) was used to survey the Enrico Fermi Atomic Power Plant and surrounding area during Sept. 1970. The survey measured terrestrial background gamma radiation and included a plume track of the stack release gases. A high-sensitivity detection system collected gamma spectral and gross-count data. The data were then computer processed into a map of a 277 sq. mile area showing isoexposure contours 3 ft above ground. Results indicated the presence of isoto… more

Some influences of regional boundary layer flow on atmospheric transport and dispersion

Description: From American Chemical Society 2nd joint conference on sensing of environmental pollutants; Washington, District of Columbia, USA (10 Dec 1973). The scales on which most atmospheric transport and diffusion work has been carried out have been either on the order of less than a few kilometers or over a few hundred kilometers. Only recently has serious attention been turned to the intermediate scale on the order of a few tens of kilometers. It is on this regional scale in the boundary layer of the… more
