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...

Development of an emission sampling system for a mobile agricultural incinerator

Creator:: Hudson, Arthur E.
Abstract:: An emmission sampling system was developed to measure pollutants emitted from a mobile agricultural incinerator developed at Oregon State University. The system was designed to collect a particulate sample on an 8" x 10" fiber glass filter and collect a gaseous sample in a plastic bag. Pollutants measured were particulates...

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,...

Comparison between lichen, conifer needles, resin-based passive air sampling devices (PASDs), and snow to monitor semi-volatile organic compounds (SOCs) in the atmosphere

Creator:: Schrlau, Jill E.
Abstract:: The purpose of this research was to compare four different media that were used to monitor SOC atmospheric concentrations in remote ecosystems. The accumulation of semi-volatile organic compounds, including pesticides, polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs), was investigated in lichen, 2-year old conifer needles, resin-based passive air sampling...

Estimates for wet and dry removals' contribution to the residence time for atmospheric pollutants in the eastern United States

Creator:: Vickers, Dean
Abstract:: The length of time that atmospheric pollutants released from low-level sources in the midwestern United States can expect to remain in the atmosphere is discussed. The pollution is assumed to be removed from the atmosphere by dry deposition and precipitation scavenging. Layer-average trajectories originating from Kansas City, Missouri are used...

Some effects of meteorological processes on the air quality in Medford, Oregon

Creator:: Pavelka, Boris R.
Abstract:: In Medford, Oregon, the major source of pollution is the lumber mill waste burner. Its low combustion efficiency results in the emission of large quantities of particulate into the atmosphere. Due to the influence of the atmospheric radiation inversion and possibly the poor performance of the burners at the time...

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...
