Can Carbon Nanotubes Cause Mesothelioma? - By: Scott Connolly

Research over the last several years suggests that the tiny fibers known as carbon nanotubes, which are used in products such as bike frames and hockey sticks, known as nanotubes, may pose a risk of mesothelioma. These nanotubes, which are about one thousandth the width of a human hair, could cause cancer in the lining of the lung. This is known as pleural mesothelioma.

Studies have shown that the shorter length nanotubes are harmless. However, the longer length nanotubes show a tendency to get stuck in the lungs and lung cavity, in a similar way that asbestos fibers do. The research found that these longer nanotubes also caused a similar reaction in the lung as asbestos.

Carbon nanotubes are a relatively new material utilized to add strength to many industrial products. Furthermore, they are extremely lightweight.

The field of nanotechnology involves modifying material down to the level of the atom. Today there are more than 1,000 nano products on the market. Carbon nanotubes are a popular material because of their combination of light weight and strength. However, with a diameter on the nanoscale and a highly elongated form, this extremely small particle has the potential to pose a health risk.

One study in Sweden conducted a few years ago discovered that extremely small fibers such as carbon nanotubes can make their way far into the lungs. In the worst case scenario, this can present an increased risk of developing cancer.

Another study conducted in Scotland more recently examined the potential for long and short carbon nanotubes to cause pathological responses known to be precursors of mesothelioma. The material was injected into the abdominal cavity of mice, which is regarded as a predictor of how these fibers will respond in human lungs and the lung lining. The study concluded that these longer carbon nanotubes showed similar effects to long, thin asbestos fibers. Asbestos fibers are harmful because they are thin enough to penetrate deep into the lungs, and long enough to resist the lung's ability to get rid of particles.

As yet, it is not known whether these long nanotube fibers will get airborne, and thus inhaled into the lungs, where they can then make their way to the sensitive lining of the lungs, or pleural. This is where most cases of mesothelioma develop.

Based upon this recent research, it is clear that more study must be conducted. These studies will then ensure the safe and responsible development of nanotechnology going forward.
