styrene polymer poisoning

Instead, it would require lab testing to determine if it is present in products, and at what levels. Integrated Risk Information System, 2014. For more information, call the ATSDR Information Center at 1-800-232-4636. Annex 13. Styrene is used predominately in the production of polystyrene plastics and resins. Overall, the available information indicates that styrene does not interfere with the estrogen-androgen-thyroid systems. [1] Leslie HA. gov/iris/subst/0104.htm. [9],[10],[11] Since the late 1970s, researchers have investigated the genotoxicity of styrene and its primary metabolite, styrene oxide (SO). acute toxicity, hearing damage and is suspected of reproductive toxicity. Styrene’s potential to affect prolactin is less clear. The styrene gas that leaked from LG Polymers which has killed at least seven people and created panic in several areas of Visakhapatnam leading … 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 nerve damage.[18],[19]. Increases in malignant mammary tumors were found in all styrene exposure groups in one study and in a second study at 600 ppm styrene but not at 1000 ppm, but a third study found a dose-related decrease in malignant mammary tumors at all styrene concentrations (50-1000) ppm styrene. Not all products we tested with styrene acrylates copolymer had detectable levels of styrene; as a result, there is no simple way to know if a product contains residual styrene. There are many studies that have examined the genotoxic potential of styrene in styrene exposed workers. It is a flammable liquid that is used in the manufacturing of polystyrene plastics, fiberglass, rubber, and latex. There is also some evidence for increased risk of cancer in the pancreas or esophagus among some styrene workers, but the evidence is weaker than that for lymphohematopoietic cancers. Studies in animals have shown that oral and inhalation exposures (concentrations > 200 – 500 ppm) to styrene can cause hearing loss due to irreversible damage within the cochlea of the ear. If you continue to use this site we will assume that you agree to our, Developmental, Reproductive, and Endocrine Toxicity. The tumorigenic response of styrene is dependent on the balance between the rate of activation and rate of detoxification, though information on these rates in humans is not available. Styrene NAC: 02/2008 vii repeated exposure of rats through gestation day 6 – 20 to 300 ppm, an increased neonatal death rate and delayed postnatal development was observed compared to … Overall, the human genotoxicity information shows a lack of evidence of consistent relationships between exposure levels and study outcome and a lack of any consistent profile of endpoints. [12] European Commission. Many commercial products are made of polystyrene, such as Styrofoam, disposable utensils, plastic dishware, and appliance casings. Styrene acrylates copolymer itself has no evidence of adverse health effects, but our tests illustrate its potential contamination with styrene. Other effects: Short-term exposure to styrene in humans results in mucous membrane and eye irritation, and gastrointestinal effects. At 100 °C it will polymerise at a rate of ~2% per hour, and more rapidly than this at higher temperatures. Styrene acrylates copolymer itself has no evidence of adverse health effects, but our tests illustrate its potential contamination with styrene. It is quickly broken down in the air, usually within 1-2 days. The CYP2F2 metabolism has been shown to be a key event (gateway) to styrene mouse lung toxicity as evidenced by both short- and long-term studies in mice where the CYP2F2 enzyme is absent have completely attenuated lung toxicity. Even in trace amounts it is concerning to have the presence of a carcinogen in products marketed to children and adults. Washington DC.
