Abstract :
A new family of air-pollution monitoring instruments is described in general terms. These new instruments are compared with conventional instrunents in terms of their respective functional capabilities. Representative examples of the new family of instruments, now in various stages of development, are described individually. Included are devices for the continuous unattended measurement of sulfur dioxide, ozone, nitric oxide, and nitrogen dioxide. Design concepts that made the above improvements possible are discussed in a search for means by which they may be extended to yield future instruments that will constitute even greater advances. Needed are transducers that will respond directly to environmentalcompositional changes reversibly and in a quasi-specific manner. Several examples are given to illustrate ways in which such devices could be applied to air-pollution monitoring.
