Hvad er sammenhængen mellem Styrofoam og kræftfremkaldende stoffer?
What is the connection between Styrofoam and carcinogens?
Styrofoam er lavet af ekspanderet polystyren, som indeholder styren, et kemikalie, der er opført af NIEHS som "med rimelighed forventes" at forårsage kræft. Imidlertid er beviserne for styren, der forårsager kræft, begrænset, og det anses generelt for sikkert til brug i mad- og drikkevareemballage af tilsynsmyndigheder.
Styrofoam is made from expanded polystyrene, which contains styrene, a chemical listed by the NIEHS as "reasonably anticipated" to cause cancer. However, the evidence for styrene causing cancer is limited, and it is generally considered safe for use in food and beverage packaging by regulatory agencies.
