Abstract |
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. Desorption of each sample was accomplished with ethanol followed by analysis using capillary gas chromatography with flame ionization detection. Analyte recovery was maximized when the gauze wipes and dermal badges were immediately extracted with ethanol after sample collection. Collection of the airborne analytes was improved over previous solid sorbent sampling methods by using a sampling train consisting of an acid treated glass fibre filter in series with a large capacity silica gel tube. The greatest recoveries of aniline and o-toluidine were from the large capacity silica gel sorbent tubes. The limit of detection for each analyte was approximately 10 times more sensitive than reported in previous NIOSH methods. |
