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 several sources. Simultaneous exposure to noise and styrene appears to increase potential adverse effects. Effects of Styrene … Styrene can stay in the air for several days. of these long-term effects include fatigue, poor coordination, difficulty in concentrating, loss of short-term memory, and personality changes such as increased anxiety, nervousness, and irritability. Health Impacts of Styrene Exposure. An updated risk assessment of styrene was completed in 2019, confirming styrene’s safety for the general population and adding to the body of knowledge on potential health effects in workplace exposures. According to scientists, inhalation of styrene gas is the major route of exposure in humans. It is likely that children would have the same health effects … You know that smell… Styrene is a common and unmistakable smell in the world of composites – the can of Bondo, the mixing of primer, maybe it’s all day every-day at work. Styrene oxide is considered toxic and possibly mutagenic. Hearing impairment—ototoxicity—is an area of concern for certain workplace exposures. Sufficient information exists to perform a meta-anal … Workers exposed to large amounts of styrene can develop irritation of the eyes and breathing passages. Styrene is largely metabolized into styrene oxide in humans, resulting from oxidation by cytochrome P450. Health Effects and Regulation of Styrene (CASRN 100-42-5) (also known as vinylbenzene, ethenylbenzene, cinnamene, or phenylethylene) o Styrene is the monomer used to make polystyrene and expanded polystyrene packaging. Studies of these effects in workers exposed mainly to styrene have been inconclusive. It has been reported that 60-70% of the inhaled gas is rapidly absorbed by the liver and lung tissues. It can react with the oxygen and form styrene dioxide which is very lethal. Exposures to styrene in humans can cause a respiration problem. With long-term and large exposures, workers using styrene have had injury to their nervous systems. Many reports in the literature suggest that long-term exposure to styrene may exert a variety of effects on the nervous system, including increased choice reaction time and decreased performance of color discrimination and color arrangement tasks. Styrene Risk Assessment. Noise protection is important for workers exposed to styrene. How can styrene affect my health? What about other health effects? It is also regarded as hazardous and carcinogen. Health effects. How Styrene Affects People’s Health. Acute (short-term) exposure to styrene in humans results in mucous membrane and eye irritation, and gastrointestinal effects. o It is a known lab animal carcinogen and a … The effects of Styrene on health can be very severe. Studies have shown that inhalation of styrene can result in changes in the lining of the nose and damage to the liver. Evaluation of potential health effects associated with occupational and environmental exposure to styrene – an update ; If you breathe high levels of styrene (more than 1000 times higher than levels normally found in the environment), you may experience nervous system effects such as changes in color vision, tiredness, feeling drunk, slowed reaction time, concentration problems, or balance problems. Styrene can enter the environment after being released by the manufacturer in the form of a gas or liquid. However, studies on animals say that animals may be more sensitive than humans to the nose and liver effects. The human health effects from exposure to low environmental levels of styrene are unknown. "Clearly, the best place to study the possible health effects of styrene exposure is in the reinforced plasticsindustry, where no butadiene is involved.
