PendergrassSumario: A comprehensive approach to estimating worker exposure to o-toluidine, aniline, and nitrobenzene using a combination of surface wipe, dermal badge, and air samples is described. Initial research efforts focused on the determination of a suitable desorption solvent for all three analytes. Then each sample collection method was evaluated to determine effects of sampling media on recovery, variations due to exposure times, storage stability, relative humidity, and flow ratesEn: American Industrial Hygiene Association journal. - Fairfax, Virginia. - Vol. 55, nº 8, August 1994 ; p. 733-7371.
