[The principles, criteria, and methods of evaluation of health hazards associated with short-term exposure to chemical atmospheric air pollutants].

The authors discuss the basic concepts of a system developed to evaluate health hazards associated with short-term exposure of different population groups to inhaled chemicals, including exposure that takes place in emergency situations. The article contains examples of acute exposition profiles for the most wide-spread air pollutants, such as nitrogen dioxide, ozone, sulfur dioxide, and carbon monoxide, developed using quantitative values of short-term exposure risk criteria.
