Abstract

Water suspensions of titanium dioxide nanoparticles were introduced intragastrically to growing male Wistar rats daily for 28 days. The data obtained revealed the presence of toxic risks related to said nanomaterials action and demonstrate the necessity of sanitary regulation of titanium dioxide nanoparticles used in food contact materials, cosmetics and other commodity.
