Abstract
A new environmental and occupational chemical monitoring system for measurement of nitrogen dioxide exposures in the range 10 ppb-l0 ppm per h is reported. The system is based on badges consisting of sol-gel entrapped o-tolidine reagent spots deposited on a poled polyvinylidene-fluoride (PVDF) piezoelectric film. Exposure is measured from the electric charge produced as a result of the stressing of the PVDF film by hear generated upon illumination of the reacted spot using a light emitting diode (LED). Calibration, effects of humidity and shelf-life data are reported and the advantages of the system are discussed.
