Laser irradiation of blue tattoo ink can create toxic byproducts - including hydrogen cyanide (HCN) - according to new research published by scientists at the German Federal Institute for Risk Assessment. Pyrolysis gas chromatography–mass spectrometry (Py–GC–MS) was performed on samples of copper phthalocyanine blue to predict the decomposition products resulting from irradiation, as part of a wider on-going project assessing the safety of tattoo inks.
