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...
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...
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...
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...
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...
