Styrene is readily absorbed and can result in toxicity following inhalation and dermal exposure [1-3]. Although no cases of styrene ingestion have been reported in humans, it is expected to give rise to systemic toxicity, similar to that seen following inhalation [1, 2]. Styrene is slightly soluble in water, soluble in ethanol and very soluble in benzene and petroleum ether. Chemicals used to treat water may also have side effects. Bull., 1985, (065), p. 25]. searches for plant toxicity information were carried out subsequently in December 2001). ASRA Local anesthetic systemic toxicity (LAST) is a rare but life-threatening complication of regional anesthesia administration. Styrene is irritating to any tissues it may come into contact with [1]. Spencer HC, Irish DD, Adams EM, Rowe VK [1942]. Polystyrene foam cups contain styrene – a chemical compound that is increasingly suspect. Both options are free, expert, and confidential. Reacts with 4- (4'-nitrobenzyl)pyridine. Human exposure to hydrocarbons is a common problem. Chronic exposure to styrene in humans results in Common symptoms of styrene exposure include irritation to eyes, nose and skin; gastrointestinal and respiratory effects. Chamblee, GA 30341-3717. Most efforts have been conducted on reducing the usage of styrene in the production of thermosets and their composites, while very few works have systematically summarized these literatures. Articles of styrene maleic anhydride copolymer are included as well. - in the short term: it can cause mild to serious nose and eye irritation, abdominal pain, sleepiness and weakness (concentra-tions of between 100 and 1,000 ppm). Benzene is a clear, liquid, petroleum-based chemical that has a sweet smell. Foam. Styrene 7,8-oxide can be further metabolized to styrene glycol (3) by epoxide hydrolase. Public Health Goals for Chemicals in Drinking Water: Styrene. Breathing high levels of styrene may cause changes in color vision, tiredness, feeling drunk, slowed reaction time, concentration problems, or balance problems. Occurrence/Use. Gentamicin toxicity accounts for between 15 to 50% of people with bilateral vestibulopathy. Styrene is a vinylarene that is benzene carrying a vinyl group. Thus, styrene-ethylene-propylene block copolymer meets the criteria for a polymer to be considered low risk under 40 CFR 723.250.
