| Abstract |
Studies were performed in three areas for the Office of Air Quality Planning and Standards to support its review of the photochemical oxidants standard: (1) the desirability of changing from a photochemical oxidants to an ozone standard, (2) the suitability of alternate ways of expressing the standard and, (3) the assessment of health risks at alternate levels of the standard. From the first study it was concluded that a change to an ozone standard could lead to benefits in administering the standard with little or no loss in protection of the public health and welfare. The second study concluded that national ambient air standards should be expressed in a statistical form. A statistical form is more in accord with the actual behavior of pollutant concentrations in the atmosphere. In the third area the mathematical methodology was developed for estimating the risk that health effect thresholds for sensitive populations will be exceeded during a given period of time at alternate levels of the ambient air quality standard. The method quantitatively treats the uncertainties in health effects thresholds and the extreme concentration levels of pollutant to be experienced in the given time period. |
