[The activity of the liver monooxygenase system in workers in contact with inorganic substances (metals, fluorine)].

The liver monooxygenase system activity was studied in 100 workers by measuring the half-life period of antipyrine and its clearance from saliva. The examined contacted with lead (22 cases), vanadium (11 cases), manganese (14 cases), fluorine (53 cases). In average, in a half of those examined the antipyrine half-life period shortened to less than 10 hours.
