Repeated inhalation of <br /> hydrocarbon solvents such as toluene can cause chronic <br /> neurological disturbances . Chronic exposure to toluene has been <br /> shown to cause hearing loss in animal experiments . The effect may <br /> be potentiated by acetyl salicylic acid and n -hexane to produce <br /> irreversible auditory damage . Prolonged and repeated exposure to <br /> toluene may cause color vision loss in humans . <br /> 12 .
