Multi-walled Nanotubes Linked to Mesothelioma in New Study, According to Surviving Mesothelioma

A new report linking synthetic multi-walled carbon nanotubes with mesothelioma says size and shape may determine how dangerous they are.

We observed highest frequencies and earliest appearances after treatment with the rather straight MWCNT types A and B.

German scientists say carbon-based synthetic molecules used in various types of materials science can cause mesothelioma that looks and acts similar to asbestos-induced mesothelioma. Surviving Mesothelioma has just posted a new article on the research. Click here to read it now.

Researchers at the Fraunhofer Institute for Toxicology and Experimental Medicine in Hannover injected 500 lab rats with multi-walled carbon nanotubes. While all of the rats eventually developed mesothelioma, how quickly it developed appeared to depend on the size and shape of the molecules.

“We observed highest frequencies and earliest appearances after treatment with the rather straight MWCNT types A and B,” writes researcher Susanne Rittinghausen.

The study, published in Particle and Fibre Toxicology, found that rats injected with more curved varieties of MWCNTs developed mesothelioma later.

“Although the vast majority of mesothelioma cases are associated with asbestos exposure, this study is a reminder to workers that asbestos is not the only toxin from which they need to protect themselves,” says Alex Strauss, Managing Editor of Surviving Mesothelioma.
