new study published by the German Federal Institute for Risk Assessment shows that metallic elements in commonly used stationery needles can easily dissolve into the bloodstream after meeting the body pigment, triggering health risks.The
study says the alloys used in stationery usually contain 6 to 8 percent nickel and 15 to 20 percent chromium, which easily dissolve into the bloodstream when encountering titanium dioxide, which is commonly found in body pigments, and eventually enters the lymphatic system and stays there, triggering allergies and affecting the body's immunity.
previous studies have shown that harmful substances in body paint can also enter the body and reach the lymphatic system. The researchers said the team stumbled across metal particles while studying the effects of body pigments, and the results were obtained from a study of body needles.
researchers stress that further long-term, large-scale studies are needed on the detailed mechanisms by which these harmful substances enter the lymphatic system affect human health.
