MAP20071020325Pristas, RobertBenzene in air : organic vapor monitors versus charcoal tubes / Robert PristasSumario: Passive badges have been utilized for many years throughout the industrial hygiene community for the sampling of organic vapors in air. A laboratory comparison was made of the 3M 3500 organic vapor monitor versus charcoal tubes in both short-term and full-shift scenarios. Back diffusion, humidity effects, concentration effects, storage stability, competing solvents, intermediate-dusration spikes, short-duration spikes, and fluctuating concentrations were all investigatedEn: American Industrial Hygiene Association journal. - Akron, Ohio. - Vol. 52, nº 7, July 1991 ; p. 297-3041.
