Tattoo nanoparticles travel inside the body
Scientists have long known that organic tattoo pigments travel to the lymph nodes because visual evidence shows the lymph nodes taking on the color of the tattoo.
Most tattoo inks contain organic pigments. However, a chemical analysis had not been done until now. The additions of preservatives and contaminants in ink revealed the presence of nickel, chromium, manganese or cobalt.
The study reports that they “were able to prove the presence of several toxic elements, such as Cr and Ni, derived from tattooing”. However, the report could not determine if other contamination sources may have contributed to the presence of toxic elements.
