AIR POLLUTION EFFECTS ON CATASTROPHIC FAILURE OF METALS
Air pollutants contribute to the catastrophic failure of metal structures through the mechanisms of stress-corrosion cracking, corrosion fatigue, and hydrogen embrittlement. The 'Silver Bridge' catastrophe, LORAN tower parts failures, aircraft parts failures resulting in accidents, and communications equipment failures are examples cited that were related to air pollution. An economic analysis of these failures indicated that accompanying injury and loss of life is an annual economic loss to the nation of from $50 million to $100 million.
