Abstract 124 workers exposed to various levels of noise and to an organic solvent mixture of toluene, ethyl acetate and ethanol underwent pure-tone audiometry and immittance audiometry testing. 49 percent had hearing loss. Of the numerous variables analyzed, age and hippuric acid (the biological marker for toluene in urine) met the significance level criteria for their contribution to the development of hearing loss. The odds ratio estimates for hearing loss were 1.07 times greater for each increment of one year of age and 1.76 times greater for each gram of hippuric acid per gram of creatinine. The findings suggest that exposure to toluene has a toxic effect on the auditory system. Topics: age-linked differences; audiometric tests; toluene; ethyl acetate; ethanol; cross-sectional study; determination in air; determination in urine; exposure evaluation; hearing loss; length of exposure; noise level; noise; organic solvents; photogravure printing; synergism.
