Scientists analyzed 12 metal tattoo needles and located that every one contained chromium and nickel. They seemed on the needles with an electron microscope earlier than and after they had been used. After a tattooing session, the needles had been abraded, with microscopic bits of nickel and chromium worn off. The report is in Particle and Fibre Toxicology.
The issue, they found, was titanium dioxide, a chemical used to brighten the colours of tattoo inks. It’s this abrasive additive that erodes the needles. The abrasion doesn’t happen when black ink alone is used.
“We can’t quantify the chance that comes with these particles,” stated the report’s lead writer, Ines Schreiver of the German Federal Institute for Danger Safety. “However generally, remember that there is likely to be dangers with tattooing, plenty of impurities that is likely to be allergenic or carcinogenic. Folks must be conscious and make knowledgeable choices about whether or not they wish to take the chance.”
