Occupational exposure to styrene was studied by environmental and biological monitoring in 22 workers employed in a fiberglass reinforced plastic factory. The mean environmental styrene concentration in individual workplaces ranged from 120 to 684 microliter/l. Blood styrene, which was tested at the end of the work shift, ranged from 450 to 3700 micrograms/l. Urinary mandelic and phenylglyoxylic acid, which were determined at the end of the work shift, ranged from 133 to 2100 and from 107 to 685 mg/l, respectively. Environmental styrene exposure was better correlated with styrenemia than with mandelicuria and phenylglyoxylicuria considered either individually or together. The ratio between environmental and blood styrene showed that styrenemia was, on average, 3.3-4.9 times higher than environmental styrene concentration.

Abstract

Occupational exposure to styrene was studied by environmental and biological monitoring in 22 workers employed in a fiberglass reinforced plastic factory. The mean environmental styrene concentration in individual workplaces ranged from 120 to 684 microliter/l. Blood styrene, which was tested at the end of the work shift, ranged from 450 to 3700 micrograms/l. Urinary mandelic and phenylglyoxylic acid, which were determined at the end of the work shift, ranged from 133 to 2100 and from 107 to 685 mg/l, respectively. Environmental styrene exposure was better correlated with styrenemia than with mandelicuria and phenylglyoxylicuria considered either individually or together. The ratio between environmental and blood styrene showed that styrenemia was, on average, 3.3-4.9 times higher than environmental styrene concentration.
