Styrene is a chemical used to make plastics, rubber, and resins—you’ll find it in items like disposable cups, food containers, insulation, and synthetic carpets. It’s also a natural component in some foods like strawberries and coffee. California’s Proposition 65 lists styrene because it can cause cancer. The International Agency for Research on Cancer (IARC) classifies it as Group 2B (possibly carcinogenic to humans), based on studies showing it may increase cancer risk with long-term exposure. The main concern is for workers who breathe in styrene fumes during manufacturing, but everyday consumer contact is generally low. To reduce exposure, avoid burning or overheating styrene-containing products. This summary draws on public regulatory data; the linked source is authoritative.

Styrene is a chemical used to make plastics, rubber, and resins—you might find it in packaging, insulation, or fiberglass boats. It's also known as vinylbenzene. The World Health Organization's International Agency for Research on Cancer (IARC) classifies styrene as Group 2B, meaning it is "possibly carcinogenic to humans." This classification is based on limited evidence from human studies and sufficient evidence from animal studies. IARC's evaluation comes from Monograph Volume 121. While styrene is common in many everyday products, the regulation focuses on potential long-term risks from exposure, especially in workplaces where people handle it regularly. The key facts are:
- IARC Group 2B: possibly carcinogenic to humans.
- Used in plastics, rubber, and resins.
- Regulated due to limited human and sufficient animal evidence.
