Abstract

New passive personal monitors for organic vapors in work places: the New Du Pont PRO-TEK<SUP>TM</SUP> G-AA Organic Vapor Air Monitoring Badge (A) and the 3M Brand Organic vapor Monitor (B), were tested under certain experimental conditions. Organic solvents adsorbed on activated carbon strip through the diffusion paths of badges were determined by means of gas chromatography and the results were compared with theoretical values. The experimental results well agreed with the theoretical values and the diffusion of organic vapors through the diffusion paths of these passive personal monitors could be estimated theoretically by the Fick's second law of diffusion. If the "relative response time" is defined as the value of Dt/L<SUP>2</SUP> at C/C<SUB>0</SUB>= 0.632, the relative response time of these samplers is 1.3. The response time of the two badges for organic vapors for toluene, ethylbenzene and ethyl acetate were caluculated from the above mentioned Dt/L<SUP>2</SUP>= 1.3, that is, 2.1, 2.2 and 1.9 seconds for A badge and 13.4, 14.0 and 12.3 seconds for B badge to each solvent respectively. From the results of this experiment, it was found that the responce time of A badge was remarkably faster than that of B badge, and even A badge needed 7-10 seconds exposure to reflect the environmental concentration.
