Generally, exposure to polystyrene cups and containers won’t be enough to cause acute symptoms in consumers, but people who live near polystyrene container plants or who work in polystyrene factories can develop side effects from contact with the substance. TWA, total dust 5 mg/m3, 8 Hr. The cups apparently lose weight during the time they are at use. Exposure Guidelines Exposure Limits PEL(OSHA) : Particulates (Not Otherwise Classified) 15 mg/m3, 8 Hr. When consuming something off a product made with polystyrene, styrene can leak into the food, especially when warmed in a microwave. Textile workers processing, among others, polyester and nylon fibers, experienced coughing, breathlessness, and reduced lung capacity , suggesting a link between microplastic inhalation and the health problems seen in these workers. Acute exposure to styrene by inhalation can give rise to irritation of the mucous membranes of the nose and throat, increased nasal secretion, wheezing and coughing. It determined that Styrofoam drinking cups leach Styrofoam into the liquids they contain. Studies evaluating inhalation exposure have demonstrated that styrene is a strong irritant [1, 2].Eye, nose and throat irritation is common at exposure levels above 50 to 100 ppm but can also occur at levels of about 20 to 30 ppm [].At very high levels chronic bronchitis type symptoms and other respiratory symptoms appear. If a large piece of styrofoam is ingested, it can cause gagging and choking. Acute (short-term) exposure to styrene in humans results in mucous membrane and eye irritation, and gastrointestinal effects. Get medical attention immediately if symptoms occur. Health Effects. First-aid measures Eye Contact Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. TWA, respirable dust TLV ACGIH): None Established Other Applicable Exposure Limits STYRENE PEL (OSHA): 100 ppm, 8 Hr. There is a chance for the piece to become stuck in the esophagus and cause mild discomfort with swallowing. Inhalation of styrene vapour is the most common route of occupational exposure [1-3]. The 350 ng/g level is one-third of levels known to cause neurotoxic symptoms. Public Contamination. Polystyrene Dishes. BMJ 283: 1610-1611. Styrene 100-42-5 Hazard Summary Styrene is primarily used in the production of polystyrene plastics and resins. Styrofoam is a foam plastic that does not break down or get absorbed into the body when ingested. If inhalation of microplastics is sufficiently high, these plastic particles may cause similar health problems. The Dangers Of Polystyrene. TWA 200 ppm, Ceiling 600 ppm - 5 Min. Max Adverse symptoms may … Poisoning from fumes from polystyrene fire. These documents provide information on the health effects of exposure, the chemical’s toxicity and material for responding to a chemical incident. Because polystyrene products are so common, many people assume they are safe, and that a government agency, such as the Food and Drug Administration (FDA), would not allow a health- threatening product to be marketed to the public. Description of Symptoms/Effects (both acute and delayed) & Symptoms of Overexposure: Inhalation: Exposure to airborne concentrations above statutory or recommended exposure limits may cause irritation of the nose, throat and lungs. Passage is somewhat dependent on the food’s fat content -- the higher the fat, the more styrene escapes. Published 1 July 2014 Last updated 16 … Styrofoam Consumption.
