Title Relationship between styrene exposure and hearing loss: Review of human studies
Bibliographic information 4th Quarter 2007, Vol.20, No.4, p.315-325. 27 ref.
Abstract Occupational exposure to styrene occurs mainly in the manufacturing of fibreglass-reinforced plastics. Since 1988, nine studies have been published on the relationship between occupational exposure to styrene and hearing loss. All studies were cross-sectional epidemiological studies or clinical studies from occupational health clinics. They involved more than 1000 workers exposed to styrene, both with and without concurrent noise exposure. Of the nine studies, seven showed some effects on the auditory system associated with styrene-alone exposure. These effects are examined using different outcome measures such as pure tone audiometry, high frequency hearing loss, and central hearing tests. In some studies, an increased risk for hearing loss was associated with exposure estimates.
