Radiation
Thorium dioxide (Thorotrast), a substance used in x-ray tests in the past has reported links to pleural mesothelioma and peritoneal mesothelioma. The use of Thorotrast has been discontinued for many years due to this discovery.
Zeolite
Some mesothelioma cases in the Anatoli region within Turkey have been linked to Zeolite, a silica based mineral with chemical properties similar to asbestos found in the soil there.
Simian Virus 40 (SV40)
Some scientists have found the simian virus 40 (SV30) in mesothelioma cells from humans and have been able to create mesothelioma in animals with the virus. The relationship between this virus and mesothelioma is still unclear, however, and further research is being conducted to gain clarity on this potential link.
Erionite Exposure
Erionite is a naturally occurring mineral that possesses properties that are very similar to those of asbestos. There have been several documented cases of mesothelioma in indivuduals living near large erionite deposits.
Carbon Nanotubes
Researchers continue to evaluate nanotube exposure as a possible risk factor for mesothelioma even though scientists have not expressed immediate concern.
