Abstract
A field test has been completed to compare the performances of dynamic and diffusive samplers for measuring styrene monomer vapors. Personal air sampling was conducted in duplicate; that is, two charcoal samplers with battery pumps and two 3 M #3500 Organic Vapor Monitors were used simultaneously. The two sampling methods were found to yield identical average results in personal air monitoring; however, the coefficient of variation observed for the charcoal tubes was dramatically higher than that found for the diffusive monitors.
