Abstract While noise is the main cause of occupational deafness, certain chemical substances can produce ototoxic effects that may make the ear more prone to acoustic assault, as opposed to noise alone. They are mainly solvents, asphyxiants, metals and pesticides, widespread in workplaces. In Quebec, over 400,000 workers are exposed to high noise levels, which raise concerns regarding the prevention of hearing impairments. This literature survey evaluated the effects of various chemical substances on hearing, and characterized the interactions between these chemical substances and noise at exposure levels respecting the current standards of the Occupational health and safety regulations. Strong interactions were found for toluene and carbon monoxide. Less solid evidence was found for other substances, with either lack of evidence or inconclusive results.
