The poisonous gas is a flammable (can be easily set on fire) liquid that is used to make polystyrene plastics, fiberglass, rubber, and latex. Styrene gas, with chemical formula C6H5CH=CH2, is also known as ethenylbenzene, vinylbenzene, and phenylethene. It is used to make several things including insulation, pipes, automobile parts, food containers, toys, shoes, among other things.

Impact of Styrene gas on Humans

Styrene is regarded as a "known carcinogen", especially in case of eye contact, but also in case of skin contact, of ingestion and of inhalation. According to reports, long-term exposure to styrene in humans results in effects on the central nervous system (CNS), such as headache, fatigue, weakness, and depression, CSN dysfunction, hearing loss, and peripheral neuropathy.

The neurotoxic properties of styrene have also been studied and reported effects include effects on vision. Health effects of styrene include irritation of the skin, eyes, and the upper respiratory tract. Acute exposure may also result in gastrointestinal effects. The gas can also lead to Immediately Dangerous to Life or Health (IDLH) document that includes acute toxicity data for styrene.

Styrene is also found in consumer products – cigarettes. Air emissions from styrene-based products include vehicle exhaust, and copy machines. According to several studies on animals, the styrene gas when inhaled can result in changes in the lining of the nose and damage to the liver. However, the effects might be severe in animals as they may be more sensitive than humans to the nose and liver effects.

The incident that took place at a polymers unit, is located in the vicinity of the Naiduthota area near Gopalapatnam. According to several media reports, several villagers fell unconscious on roads while fleeing from the affected areas in the village. More than a 1,000 people in five surrounding villages, in a three km radius, have been reported sick and as many as 1500 people have been evacuated.
