However, it was not possible to establish whether the American workers contracted leukaemia from handling styrene or from butadiene, a chemical, which is styrene's permanent companion in the production of synthetic rubber -- and this is where the Danish register-based studies come into the picture. The International Agency for Research on Cancer (IARC) has announced the . After 40 years in limbo: Styrene is probably carcinogenic. Many companies take measurements, but they are not publicly available. [1] [2]Professor Henrik Kolstad of Aarhus University in Denmark said:“The most recent styrene study shows the risk of acute myeloid leukemia, a rare form of leukemia, is doubled.Out of the more than 70,000 people included in the research project, we found 25 cases of acute myeloid leukemia, where you would statistically expect to find 10.”The American Cancer Society (ACS) estimates that 19,520 new cases of acute myeloid leukemia will be diagnosed in the U.S. in 2018, and the disease is expected to kill 10,670 people. [3]In addition to Styrofoam, styrene is used in synthetic rubber, some insulation materials, disposable cutlery, plastic packaging, and fiberglass plastic.The U.S. Centers for Disease Control (CDC) has warned that people may be exposed to small amounts of styrene if it gets into food packaged in polystyrene containers, including Styrofoam.The researchers also looked for potential links between styrene exposure and Hodgkin lymphoma, and T-cell lymphoma, but did not spot the same link.

Now, according to the International Agency for Research on Cancer (IARC), A team of 23 scientists hand-picked by the IARC looked at the records of more than 70,000 people who worked in the Danish plastics industry between 1968 and 2011. wind turbines or yachts.The study has involved a comprehensive linkage of registers, where the researchers used the central business register , along with various other company registers, to identify the relevant companies and their employees.

We have therefore mapped the cancer incidence for those who worked in companies that used styrene in the production during the period 1968-2011," explains Henrik Kolstad on the background for what has ended up being the world's largest epidemiological study of styrene exposure in the reinforced plastics industry.In the research project, PhD student Mette Skovgaard Christensen, Henrik Kolstad and their research colleagues followed 73,036 employees who during the period 1968-2011 worked in one of the 456 small and medium-sized companies in Denmark that have used styrene in the production of e.g.
