Not only tattoo colors, but also those used points can probably allergies trigger. "When tattooing chrome and nickel particles points and enter the lymph nodes via the blood, "explains Ines Schreiver of Federal Institute for Risk Assessment (BfRin BerlinShe published a study Tuesday with her colleagues in the journal "Toxicology of Particles and Fibers".
Random discovery: Toxic metals detected in common tattoo needles during the examination
As a result, metals causing allergies dissolve particularly frequently when titanium dioxide is used, contained in many tattoo colors such as green, red and blue. Tattoo needles are made from an alloy that also contains six to eight percent nickel and up to 20 percent chromium. Both metals are toxic and can allergies trigger when they break down.

The new realization was noisy Schreiver Coincidence: "We discovered metallic particles when we examined tattoo inks." In detective work, we discovered that they came from the attrition of points come ". In a previous study, researchers had previously shown that the toxic pigments of tattoo inks could accumulate for years in the lymph nodes. Now, it has been shown that particles of points to fight a path in these organs of the immune system, Schreiver,
To what extent do deposits damage health and allergies trigger, would need to be explored more closely. This would require in-depth studies with several thousand participants over several years. If colorful tattoos are more dangerous than blacks tattoos, could not say exactly. "The lower black color may also contain nickel at high concentrations," the researchers said.
