Tatouage : le synchrotron de Grenoble prouve que les nanoparticules des encres s’infiltrent partout<\/a><\/h4>\n\n\n\n

Les \u00e9l\u00e9ments qui composent l’encre des tatouages se d\u00e9placent dans le corps sous forme de micro et nanoparticules, et ce jusqu’aux ganglions lymphatiques. C’est ce que d\u00e9montre une \u00e9tude publi\u00e9e ce mardi 12 septembre par une \u00e9quipe de chercheurs de l\u2019ESRF, le synchrotron europ\u00e9en de Grenoble.<\/p>\n\n\n\n

On se doutait bien que les pigments inject\u00e9s lors du tatouage ne restaient pas seulement au niveau de la peau.<\/p>\n\n\n\n

Le synchrotron de Grenoble en apporte aujourd\u2019hui la preuve dans une \u00e9tude publi\u00e9e ce mardi 12 septembre 2017 par la revue Scientific Reports.<\/p>\n\n\n\n

Ses auteurs, une \u00e9quipe compos\u00e9e de scientifiques grenoblois mais aussi de chercheurs allemands, ont pu localiser notamment du dioxyde de titane, dans les ganglions lymphatiques de personnes tatou\u00e9es. C’est un pigment blanc couramment utilis\u00e9 dans les encres de tatouages. Il sert de base pour certaines nuances de couleurs.<\/p>\n\n\n\n

Pour obtenir ces r\u00e9sultats, l\u2019\u00e9quipe a utilis\u00e9 les rayons X ultra puissants de deux laboratoires sp\u00e9cialis\u00e9s de l\u2019ESRF.<\/p>\n\n\n\n

\u201cQuand quelqu’un veut se faire un tatouage, il est souvent tr\u00e8s soucieux de choisir le bon salon, celui o\u00f9 les normes sanitaires sont respect\u00e9es, celui o\u00f9 des aiguilles st\u00e9riles neuves sont utilis\u00e9es. Mais, personnes ne se pose la question de savoir quelle est la composition chimique des couleurs utilis\u00e9es pour les tatouages. Notre \u00e9tude montre qu\u2019il le faudrait!\u201d souligne Hiram Castillo, l’un des auteurs de l’\u00e9tude, scientifique \u00e0 l’ESRF.<\/p>\n\n\n\n

Car les nanoparticules resteront \u00e0 vie dans les ganglions et le probl\u00e8me, c’est que les effets sur la sant\u00e9 ne sont pas connus pour l’instant. Prochaine \u00e9tape pour les chercheurs : analyser d’autres \u00e9chantillons de patients tatou\u00e9s pr\u00e9sentant des effets ind\u00e9sirables, et relier \u00e9ventuellement ceux-ci aux propri\u00e9t\u00e9s des pigments utilis\u00e9s sur leur peau.<\/p>\n","protected":false},"excerpt":{"rendered":"
