title: Performance evaluation of a gasoline vapor sampling method.
abstract: A study has been conducted to evaluate the performance of the method used by Exxon to monitor worker exposures to gasoline vapors. The study specifically addresses the effects of temperature and humidity on breakthrough volume as an indicator of performance limits. Results indicate that a 600 mg charcoal tube will yield excellent results if sample flow rate is adjusted properly with regard to absolute humidity. In order to aid the field hygienist in applying the study results, charts that relate sampling parameters to environmental conditions are presented.
