Abstract:

OBJECTIVE: To evaluate the effects of simultaneous exposure to noise and solvents on hearing of workers. MATERIAL AND METHODS: This is a historical cohort study, conducted through document analysis (risk agents and audiometry) Metallographic industry, including: Medical Control Program and Occupational Health (PCMSO), Hazard Prevention Program Environmental (PPRA), Environmental Assessment Quantitative Chemical Agents, Risk Map and Medical Records staff, including laboratory tests and pure tone audiometry. The sample (n = 198) was divided into four groups: noise (GR - n = 42) - exposed only to noise, noise and solvents group (GRS - n = 57) - simultaneously exposed to noise and solvents; Noise Control Group (CR - n = 42) and Control noise and solvents (CRS - n = 57) - the database of the Department of Audiology at the University of Tuiuti/PR without exposure to noise and solvents. RESULTS: The GR had 16.66% of cases suggestive of Noise Induced Hearing Loss (PAIR) and bilateral GRS 5.26%. The GR and GRS had worse thresholds than their respective control groups. The females presented less susceptible to noise than men, however, when simultaneously exposed to solvents, the hearing was affected similarly to males resulting significant differences (p <0.05). CONCLUSIONS: The results found in this study indicate that simultaneous exposure to noise and solvents caused an auditory damage in the peripheral auditory system of workers. Significant differences were observed in workers of both genders.
