Abstract
The U.S. Environmental Protection Agency is considering an additional ambient air quality standard for sulfur dioxide that would be based on an average value over a 5-minute period. In planning for such a standard, issues such as “How well do currently used ambient air instruments respond to high concentrations over short time periods?” and “What changes might have to be made to monitoring equipment to accommodate the proposed standard?” must be considered.
This article Investigates these issues with information obtained from the literature, instrument manufacturers, state and local air monitoring agencies' ambient air measurements, laboratory tests of currently used fluorescence-type sulfur dioxide analyzers, and mathematical models of instrument responses. Models were derived from the laboratory data and exercised to predict instrument response to various pollutant challenges. This article will emphasize the development and testing of the model.
