Tattoo ink contaminants can end up in lymph nodes, study finds

Particles of colour, which can be tainted with toxic impurities, can make their way to key immune system sites, researchers say

The tiny particles – measuring a few millionths to a few billionths of a centimetre – include molecules from preservatives and contaminants such as nickel, chromium, manganese and cobalt, researchers reported in the peer-reviewed journal Scientific Reports.
