  Définition

  Introduction into the atmosphere of substances that are not normally present therein and that have a harmful effect on man, animals, or plant life.

  Note :

  Important among these ((substances)) are sulfur dioxide, which forms sulfuric acid on contact with water vapor; automotive exhaust emission products (carbon monoxide, lead compounds, polynuclear hydrocarbons, nitrogen oxides); toxic metal dusts from smelters, coal smoke, and other particulates; formaldehyde and acrolein; and radioactive emanations. Control of these is exercised by the Environmental Protection Agency. *As conventionally used, the term does not apply to interior air spaces such as industrial workrooms. Tolerances for the latter are established by the American Conference of Governmental and Industrial Hygienists (ACGIH).
