It seems as if Nanotubes may pose similar health risks as asbestos. Discovered in 1991, Nanotubes are basically rolled-up carbon sheets—tiny, super-strong carbon fibers—used to produce materials much lighter and stronger than steel. Nanotubes are found in a variety of common products, such as tennis rackets.
Scientists have long wondered whether needle-shaped Nanotubes might cause similar diseases to those caused by needle-shaped asbestos fibers. Breathing high levels of asbestos fibers is linked to increased risks of lung cancer, mesothelioma—a cancer of the lining of the chest and abdominal cavity—and asbestosis—in which lungs become scarred with fibrous tissue.
