Sampling and analytical methods are described for the determination of airborne exposures of individuals to ethylenimine - an OSHA designated carcinogen. The personal sampler consists of a midget bubbler containing Folin's reagent capable of quantitatively absorbing ethylenimine vapors. The derivatized imine is extracted with chloroform and determined by high-performance liquid chromatography. The method was evaluated with dynamically generated samples in the range of 1. 2-794 mu g/sample and yielded an average recovery of 92. 1% with a pooled coefficient of variation of 0. 042.
