Styrene (C6H5CH=CH2), also known as ethenylbenzene, vinylbenzene or phenylethene, can damage eyes and the skin and even cause death if ingested or inhaled.

Acute exposure to high vapour concentrations of the gas that had leaked in Bhopal, methyl isocyanate (H3C-N-CO), may cause severe pulmonary oedema and injury to the alveolar walls of the lung, severe corneal damage, and death. Survivors of acute exposures may exhibit long-term respiratory and ocular effects.
