Here's what to know about the chemical and its harmful health effects. What is styrene? Styrene is a colorless, flammable liquid with a sweet odor, according to the National Institute of ...
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. [20] [33] [34] [35] Styrene is largely metabolized into styrene oxide in humans, resulting from oxidation by cytochrome P450.
Humans are exposed to toxic chemicals and microplastics at all stages in the plastics life cycle. Microplastics effects on human health are of growing concern and an area of research. The tiny particles known as microplastics (MPs), have been found in various environmental and biological matrices, including air, water, food, and human tissues.
In August 2005, styrene began leaking from a rail car in Cincinnati's East End. That was not the result of a derailment, but the leak forced evacuations and shelter-in-place orders for residents.
Styrene oxide is a main metabolite of styrene in humans or animals, resulting from oxidation by cytochrome P450. It is considered possibly carcinogenic from gavaging significant amounts into mice and rats. [4] Styrene oxide is subsequently hydrolyzed in vivo to styrene glycol by epoxide hydrolase. [5]
Here's what the Drug & Poison Information Center at Cincinnati Children’s Hospital advises regarding returning home following the styrene leak.
IARC group 2B substances, mixtures and exposure circumstances are those that have been classified as "possibly carcinogenic to humans" by the International Agency for Research on Cancer (IARC) as [1] This category is used when there is limited evidence of carcinogenicity in humans and less than sufficient evidence of carcinogenicity in experimental animals.
Officials said a chemical reaction caused styrene, which is naturally a liquid, to heat up into a gaseous state. This chemical reaction caused the tank’s pressure valve to open and release gas ...
