Effects of Air Pollution on Materials and the Economy

The use of weather and climatological data in evaluating the durability of building components and materials

“…However, in urban areas, hydrogen sulfide may be a pollutant problem as for example, in causing the darkening of lead based paints [63],…”

“…Acid mists of this type may cause serious deterioration of a variety of building materials, including metals, organic coatings, and stone [63], Nylon is a well know example of a polymer which is attacked by sulfur dioxide and sulfur trioxide dissolved in water in the form of a mist. Nitrogen dioxide gas can also combine with water vapor to form nitric acid.…”

“…Seawater salt spray is a factor in the deterioration of materials in areas close to the seacoast. The effect of salt spray is confined to a distance of only a few hundred yards inland [63] . The chief effect of salt spray is to increase the corrosion of metals including those coated with porcelain enamel.…”

Automobiles and Air Pollution

“…Only 330 of these establishments returned usable data. 6 Although the questionnaire was detailed, the published information from the questionnaires includes only the following seven categories of pollutants emitted: aldehydes, carbon monoxide, hydrocarbons, nitrogen oxides, sulfur oxides, particulates and benzopyrene. The extreme broadness of these categories severely restricts the usefulness of the published summary.…”

Fundamentals of corrosion control design

“…Published information on the disperal of these effluents (29,31) can be used to advantage by the designer in locating facilities so that exposure to adverse conditions will be kept to a minimum. Of great importance in combating the potential corrosion effects of air pollution is knowledge of wind direction persistence.…”
