Popis: Administration of ethanol in several doses during human exposure to styrene can inhibit the urinary mandelic and phenylglyoxylic acid excretion in a way similar to that reported when ethanol was administered as a single dose. Sensitivity to this inhibitory effect has been found to differ with individual subjects. Differences in long-term consumption of ethanol resulting in different induction of the oxidizing enzymes are suggested to account for this finding. Intra-individual variation in the influence of acute ethanol ingestion on the excretion rate of the mentioned acids can also occur. The habit of drinking ethanol might be important, even for partial redirection of the styrene metabolism from styrene glycol oxidation to styrene glycol conjugation with beta-glucuronic acid and/or sulfate. The consequences of these observations for the occupational hygiene practice are briefly outlined.
