Nanoparticles in tattoo ink could cause cancer
Researchers from the UK’s University of Bradford have warned that some tattoo inks could cause illnesses, including cancers. This led Friends of Earth to call for urgent regulation of these toxic nanoparticles. These can be transported to other organs in the body through blood and lymphatic vessels, accumulation in organs such as the spleen or the kidneys, leading to illnesses. Black tattoos inks seem to be the most polluting: these are usually made of carbon nanoparticles despite carbon black being classified as possibly carcinogenic. Carbon black nanoparticles have also been shown to damage DNA.
