  1. Evaluation of organic solvent ototoxicity by the upper limit of hearing.

    Article - En anglais

    To clarify the effects of organic solvents on hearing, we measured the upper limit of hearing in 93 male workers exposed to organic solvents in 7 factories that produced plastic buttons or baths.

    Medical examinations, environmental monitoring (i.e., concentration in breathing-zone air), and biological monitoring (i.e., concentration in urine) of the organic solvents were also done.

    Although the organic solvent concentrations in the environmental monitoring were lower than the occupational exposure limit, the upper limit of hearing was reduced in workers who were exposed for 5 y or more.

    This reduction was dose-dependent and was related to styrene concentrations in breathing-zone air and mandelic acid concentrations in urine.

    Even individuals who had normal medical examinations showed a reduced upper limit of hearing.

    The upper limit of hearing may serve as an early detection indicator of health effects in workers constantly exposed to styrene.
