Popis: | Background Studies suggest metal and solvent exposure may damage hearing. This study evaluated the association between exposures classified as high for metals, solvents, and noise on permanent threshold shift (PTS) development. Methods A total of 1,546 personnel at an industrial shipyard were divided into five exposure groups based on level of concentration: high noise, high metals/solvents, high metals/noise, high metals/solvents/noise, and a low metals/solvents/noise reference group. Hearing threshold changes were analyzed to identify development of a PTS. Results Logistic regression indicated high metals/solvents and high metals/solvent/noise groups had significantly greater odds ratios of 2.4; 95%CI [1.02, 2.85] and 1.7; 95%CI [1.46, 3.94], respectively, compared to a reference group. Both groups were associated with PTSs while controlling for age, gender, and exposure duration. Conclusions Simultaneous exposures classified as high for metals and solvents may damage hearing. Results suggest the need for expanding hearing conservation programs to consider combinations of exposures to metals, solvents, and noise. Am. J. Ind.
