Some dangerous chemicals are Ototoxic (i.e. poisonous to the ear) and a synergy has been noted between noise and some organic solvents where they are used in a noisy environment.

Ototoxic chemicals may damage the cochlea in the inner ear and/or the auditory neurological pathways leading to hearing loss, tinnitus and vertigo. It is more likely persons will experience hearing damage through a combination of chemicals and noise.

The direct evidence is limited; however awareness of this fact should be taken into account during risk assessments.

• Benzene
