Scientists have found hints on toxicity and carcinogenicity of tattoos - RIA Novosti, 9/13/2017
MOSCOW, 13 Sep – RIA Novosti. The French nuclear physicists have found out that the nanoparticles which are contained in ink for tattoos can get from skin into lymph nodes and extend on all organism, it is told in article published in the Scientific Reports magazine. "When someone wants to make a tattoo, similar people usually very carefully approach the choice of a tattoo salon. For example, their workers have to use sterile needles for stuffing of each drawing. On the other hand, nobody ever checks the chemical composition of ink, but our research shows that it should be done" — Hiram Castillo from the European synchrotron center in Grenoble (France) tells. © Photo: The tattoo on the Egyptian mummy has delivered to Anne Austinzagadochnaya scientists in tupiktatuirovka are one of the most ancient examples of the fine arts created by the person. As today scientists consider, leaning on Ancient Egyptian mummies and traces of pigments in burial grounds of more ancient inhabitants of Earth, people have learned to apply constant tattoos on the body even before origin of a civilization, and since then this art became an immense part of secular and religious culture of many people of the world. The ancient nature of this art as Castillo and his colleagues tell, forces many people to consider that tattoos in itself don't do harm to health of the person and have no side effects. Experiments which scientists from France made on skin pieces by means of accelerators of particles have shown that it not so. As scientists tell, tattoos have interested them after one of authors of article has got acquainted with composition of ink which is usually used for stuffing of drawings, and has found out that they comprise particles of titanium dioxide and other potentially toxic substances. Molecules of dioxide of the titan as recently physicians have found out, can cause inflammations and other unpleasant effects at hit on skin that has forced scientists to track how they travel around an organism, using ID21 and ID16B accelerators. © AP Photo/Martin Meissnerneandertaltsy have learned to do tattoos at kromanyonets - ученыеЗаручившись by the consent of four volunteers, scientists cut out small pieces of skin from their tattoos and have illuminated them by means of the X-ray developed by these accelerators and have checked whether ink from a tattoo "runs". It has turned out that it really occurs and that dioxide of the titan and other components of paint filtered from a tattoo into more deep skin layers, accumulating in lymph nodes. In this way only small particles of pigments whose sizes didn't exceed several tens of nanometers behaved. Larger fragments of paints remained in drawings. Hit of nanoparticles in lymphatic system as have shown the subsequent experiments, hasn't taken place completely for an organism of volunteers – their lymph nodes have extended, and their cages and skin have begun to allocate a special set of molecules contributing to the development of inflammation and on
