Styrene, a common ingredient in many plastic items, now deemed to be “probably carcinogenic” by WHO

Natural News – Aug 23, 2018

The World Health Organization’s International Agency for Research on Cancer (IARC) has now upgraded the cancer-causing status of the common plastic ingredient styrene. The move came in response to the results of a comprehensive study carried out by researchers from Aarhus University, along with new animal evidence.

More than 70,000 people were included in the register-based research. The scientists looked at the incidence of acute myeloid leukemia, which is a rare form of leukemia that has been associated with styrene exposure. In a population of this size, the researchers would statistically expect 10 patients to have the disease. Instead, they found 25 cases of the illness, leading them to conclude that the ingredient is even riskier than once believed.

They also found a fivefold higher risk for a specific type of nasal cancer among those who have been exposed to styrene.

In response, the IARC has upgraded styrene from being “possibly carcinogenic” to being “probably carcinogenic” to humans. The announcement will be published as a monograph – a special type of impartial research report that countries can use as a basis for legislation – written by 23 researchers from all over the world. These researchers reviewed and reevaluated the chemical’s risk in light of the latest research on exposure to styrene, including human epidemiological studies, mechanism studies, and experiments with animals.

You can find styrene in synthetic rubber, disposable tableware, fiberglass plastic, Styrofoam and some other types of packaging, and insulation materials.
