  • A study of field burning under varying environmental conditions

    Creator:
    Meland, Bruce Roger
    Abstract:
    A field study on grass field burning was conducted in the Willamette Valley of Oregon during the summer of 1965. Approximately 243,000 acres of grass fields are burned in the valley during August and September. Serious air pollution problems result from this burning. The purposes of the study were to...

  • The effects of various pre-weighing procedures on the reported weights of air pollutants collected by filtration

    Creator:
    Kowalczyk, John F.
    Abstract:
    A study was conducted to determine what effects the type of pollutants, storage conditions, storage time, and method of sample conditioning have on the reported weight of an air pollutant collected by filtration. Samples were collected from a refuse dump, an arc furnace smelting nickel ore, and a rotary kiln...

  • Effectiveness of a fluidized bed in filtration of airborne particulate of submicron size

    Creator:
    Black, Charles Hartgraves
    Abstract:
    Submicron particulate (mean size of 0.52 microns) was filtered from air at substantially atmospheric temperature and pressure by passing air up through a bed of fluidized glass shot in a two inch column. Removal efficiency, defined as the percentage removal of particulate from the air stream, was essentially constant during...

  • 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,...

  • A model of ciliary streaming in the respiratory system

    Creator:
    Chambers, Alan B.
    Abstract:
    The respiratory tract is lined with a mucous blanket which is motivated by a ciliated epithelium. This blanket includes a lower serous layer of fluid through which the cilia beat and an upper viscid layer into which particulates from the inhaled air are deposited. The movement of the mucous blanket...

  • Particulate and total gaseous hydrocarbon emissions from a gas heated veneer dryer

    Creator:
    Shigehara, Roger T.
    Abstract:
    A source test was conducted to determine the particulate and the total gaseous hydrocarbon emissions from a gas heated veneer dryer. Samples were taken on eight separate days from the exhaust stacks while the dryer was processing Douglas fir veneer. Of the eight days, three was used to determine the...

  • 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...

  • An investigation of the removal of ozone by activated charcoal

    Creator:
    Liffick, Glenn Lonngren
    Abstract:
    The removal of ozone from an air stream by activated-cocoanut charcoal was investigated from the literature and experimentally. The experimental investigation showed that activated-cocoanut charcoal can be used to remove concentrations of ozone less than 1.0 ppm with high efficiencies. The mechanism of the ozone removal appeared to be a...

  • 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,...

  • An experimental investigation of aerosol coagulation in the shock tube

    Creator:
    Yun, Kyung Woo
    Abstract:
    Ammonium chloride aerosols of submicron size generated by condensation and dispersion methods were treated, shortly after aerosol charging, with shock waves originating from diaphragm pressure ratios of up to 5.75. The fraction of the particulate matter remaining in suspension after a given time was measured as an indication of coagulation...
