The time course of mandelic and phenylglyoxylic acid excretion in workers exposed to styrene under model conditions. 1979

H K Wilson, and J Cocker, and C J Purnell, and R H Brown, and D Gompertz

Urinary excretion of mandelic and phenylglyoxylic acids by two technicians building glass-reinforced plastic boats has been measured over a 7-day period. Peak excretion of both metabolites occurred several hours after the end of exposure. There was little relationship between urinary mandelic acid concentrations measured at the end of shift and the maximum excretion observed in samples collected after this time. It is suggested that sampling strategies devised to monitor workers exposed to styrene should reflect maximum excretion rates of urinary mandelic acid.
