By.Evaluating the hearing of painting workers with exposed to noise a mixture of organic solvents.(including vapor xylene, toluene, vapor etc.) at concentrations anticipated, as safe Metwally.Et al. Found elevated hearing impairment compared to workers exposed to, noise only suggesting.That the solvent exposure contributed process of hearing loss [12]. In this study our results,,Showed significantly higher TVOCs at, MSWL worksite and some of them were much higher.Than that of the OSHA standard; therefore hearing impairment, by exposure to TVOCs should.Not be neglected when considering the cause of hearing loss among MSWL workers.Various studies have shown that age smoking and, some other factors are associated with.Higher prevalence of hearing loss [12 22 23,,]. In the present study we used, stratified analyses by.These confounders to learn the prevalence of hearing loss and obtained, similar results. The.Prevalence of hearing loss in MSWL workers (Group 3) was significantly higher than that in.Group 1 and group 2 although a, few of them did not reach statistically significance partly because,,Of their small sample sizes. From multivariate, Logistic regressions our study did not suggest.Any association between hearing loss among MSWL workers and, selected characteristicsIncluding gender age years of education,,,, smoking and drinking status duration of work and.
