inhaling titanium dioxide

In addition to coated papers, titanium dioxide is also used in the production of specialty papers, such as those used for labels, packaging, and security documents. In these applications, titanium dioxide is added to the paper pulp to increase the opacity and brightness of the paper. This helps to create a more professional and appealing appearance for the final product, as well as providing enhanced security features through the use of fluorescent or UV-reactive titanium dioxide particles

In 2017, French researchers from the Institut National de la Recherche Agronomique (INRAE) were among the first to examine the effects of E171 nanoparticles on the body. They fed rats a dose of 10mg of E171 per kilogram of body weight per day, which was similar to human exposure in food. The research, which was published in Scientific Reports, showed that E171 was able to traverse the intestinal barrier, pass into the bloodstream, and reach other areas of the body in rats. Researchers also found a link between immune system disorders and the absorption of titanium dioxide nanoparticles.
