Methods of measurement for the determination of gaseous air pollutants
Abstract
Effective and efficient approaches for preventing a pollution of the air must be based on reliable data regarding the type, the amount, and the distribution of the pollutants. The employment of appropriate analysis techniques is needed for obtaining the required data. A description is presented regarding some of the possibilities and problems concerning the measurement of gaseous pollutants. The planning of sampling procedures and techniques as a vital first step in the measurement program is considered. Statistical approaches are to be used to determine the most efficient form for the sampling program with regard to local and temporal characteristics. Selected analytical procedures for the determination of gaseous air pollutants are discussed, taking into account the colorimetric analysis of a trace component concentrated in an absorbing liquid, a personal monitoring device for gaseous contaminants, analyzers based on electrolytic conductivity, and polarographic-coulometric analyzers for measuring low concentrations of sulfur dioxide. Trends leading to the development of an automatic trace-gas analysis procedure are also considered.
