For example, China does not even consider chrysotile to be a form of asbestos and many regulations in other countries apply to all forms but chrysotile. New research is slowly highlighting that belief’s inaccuracy.

A study recently featured in Science Trends took to task the idea that occupational exposure to asbestos types other than chrysotile primarily cause , which affects the lining of the abdomen as opposed to the heart or lungs. The researchers studied 51 men and 11 women with peritoneal mesothelioma who were exposed to both amphibole and chrysotile asbestos.

Sole chrysotile exposure was documented in 14 of the 62 cases, and seven of those were found to be due to secondhand exposure, also known as paraoccupational asbestos exposure. Secondhand exposure occurs when workers transfer asbestos fibers from work to other places through clothing, tools, vehicle, etc. and put others at risk of contracting an asbestos-related illness. Most of those cases were women laundering the clothes of family members who worked around asbestos.

The study concluded, “(Peritoneal mesothelioma) occurs with both occupational and paraoccupational exposures to asbestos and may be seen in paraoccupational exposures to chrysotile asbestos.”

The study’s results support what many anti-asbestos activists have long said: No safe level of exposure exists for any type of asbestos. The Occupational Health and Safety Administration even notes that exposures as short as a few days have caused mesothelioma in humans.
