Feasibility of utilizing an integrating nephelometer to measure visibility

Creator:: Nelson, William George
Abstract:: An integrating nephelometer was set up at the Eugene Airport which is located five miles north of Eugene, Oregon, on Highway 99 West. Continuous atmospheric scattering coefficient readings were obtained from July 1, 1969, to August 28, 1969. These data are converted to meteorological range through the use of the...

Airborne sampling of particles emitted to the atmosphere from Kraft paper mill processes and their characterization by electron microscopy

Creator:: Augustine, Frank Edward
Abstract:: A high volume sampling system, employing Nuclepore filters and designed for sampling particulate in the plumes from industrial sources using a light aircraft, is described. The effluent of kraft paper mills was sampled using this system and then analyzed by electron microscopy. Size distributions of particles were obtained at several...

Partial recirculation of diesel engine exhaust for the reduction of oxides of nitrogen

Creator:: Addicott, Donald James
Abstract:: Oxides of nitrogen are a concern as effluents to atmospheres because they participate in photochemical reactions which produce smog, because they attenuate sunlight which gives the atmosphere a reddish brown cast, and because of their toxic properties and the health hazards associated with the photochemical products they produce. Oxides of...

Relationships between air quality and thermal structure of the lower atmosphere at Salem, Oregon

Creator:: McElroy, James L.
Abstract:: The examination in some detail of the relationships between air quality and the thermal structure of the lowest layers of the atmosphere constituted the primary objective of this thesis. Data for the study were assembled during April-June 1965 at the U.S. Weather Bureau Station, McNary Field, Salem, Oregon. The measures...

An emission sampling device installed operated, and retrieved from ground level

Creator:: Wise, Kenneth Raymond
Abstract:: The "Teepee" type wood residue incinerator, similar to many other sources, requires sampling at the point where the emissions enter the atmosphere. Because the location of the emission point is hazardous and unpleasant for the operation of a sampling probe, a portable, tilt-up column was developed which permitted installation, operation,...

Agricultural field burning plume rise

Creator:: Azarbaijani, Masoud
Abstract:: Many agricultural fields are burned in the Willamette Valley of Oregon during the summer for economic reasons. A major air pollution problem results from these burnings. The purpose of this study was to develop relations between the maximum plume height and some of the independent variables affecting this plume height,...

The effect of air injection at the exhaust ports of a gasoline engine on the oxides of nitrogen emissions

Creator:: Reid, Richard Stowell
Abstract:: The importance of automobile exhaust as a source of atmospheric pollutants has been recognized for several years. With the control of stationary sources in geographic areas such as Los Angeles County, the automobile has become the major uncontrolled source of air pollution. The three major pollutants emitted by automobiles are...
