Page 34 - Fundamentals of Air Pollution

III. The Twentieth Century 13

Technological interest during these 30 years has focused on automotive
air pollution and its control, on sulfur oxide pollution and its control by
sulfur oxide removal from flue gases and fuel desulfurization, and on
control of nitrogen oxides produced in combustion processes.
Air pollution meteorology came of age and, by 1980, mathematical models
of the pollution of the atmosphere were being energetically developed. A
start had been made in elucidating the photochemistry of air pollution. Air
quality monitoring systems became operational throughout the world. A
wide variety of measuring instruments became available.
