When consuming something off a product made with polystyrene, styrene can leak into the food, especially when warmed in a microwave. 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. If a large piece of styrofoam is ingested, it can cause gagging and choking. Styrofoam is a foam plastic that does not break down or get absorbed into the body when ingested. Polystyrene Dishes. Polystyrene latex microsphere, 1 micron, dryform Revision Date 14-Feb-2020 4. 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. Public Contamination. The Dangers Of Polystyrene. Styrofoam Consumption. Max It determined that Styrofoam drinking cups leach Styrofoam into the liquids they contain. Published 1 July 2014 Last updated 16 … If inhalation of microplastics is sufficiently high, these plastic particles may cause similar health problems. Get medical attention. TWA 200 ppm, Ceiling 600 ppm - 5 Min. The cups apparently lose weight during the time they are at use. Get medical attention immediately if symptoms occur. 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. Passage is somewhat dependent on the food’s fat content -- the higher the fat, the more styrene escapes. 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. These documents provide information on the health effects of exposure, the chemical’s toxicity and material for responding to a chemical incident. BMJ 283: 1610-1611. Poisoning from fumes from polystyrene fire. Adverse symptoms may … Skin Contact Wash off immediately with plenty of water for at least 15 minutes. The 350 ng/g level is one-third of levels known to cause neurotoxic symptoms. Acute (short-term) exposure to styrene in humans results in mucous membrane and eye irritation, and gastrointestinal effects. Inhalation of styrene vapour is the most common route of occupational exposure [1-3]. 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. Styrene 100-42-5 Hazard Summary Styrene is primarily used in the production of polystyrene plastics and resins. TWA, respirable dust TLV ACGIH): None Established Other Applicable Exposure Limits STYRENE PEL (OSHA): 100 ppm, 8 Hr.

Exposure Guidelines Exposure Limits PEL(OSHA) : Particulates (Not Otherwise Classified) 15 mg/m3, 8 Hr. 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.
