Urinary styrene in the biological monitoring of styrene exposure.
Scandinavian Journal of Work, Environment & Health, 1993 The urinary excretion of styrene represents a promising indicator of exposure to this solvent. Nevertheless extensive research under field conditions is scant. In this investigation 214 styrene-exposed workers from 10 fiberglass-reinforced plastics factories were studied. Environmental monitoring was performed by personal passive sampling.
