Titanium dioxide
nanoparticles (TiO
2
NP) are present in several daily use products, and the risks associated with their bioaccumulation must be stablished. Thus, an evaluation of several toxicological-related effects was conducted after intraperitoneal injection of TiO
2
NPs in mice. Mice were divided into two groups, which received 2 mg kg
-1
day
-1
of TiO
2
NPs or vehicle saline. Assessments of body and organ weight as well as biochemical, hematological, and histopathological analyses were performed in order to evaluate adverse effects. The results showed that treatment resulted in an increased visceral and abdominal fat deposition, as well as a mononuclear inflammatory infiltrates in the abdominal fat tissue. The TiO
2
NPs induced significant decrease in the weight gain and
splenomegaly
. Additionally, TiO
2
NP-treated mice showed altered hematological parameters and significant liver injuries, which were characterized by histopathological and biochemical changes. Our results also indicated that TiO
2
NPs were absorbed and significantly accumulated in the spleen, liver, and kidney. These results showed the ability of TiO
2
NPs to infiltrate different organs and to induce inflammation and liver and spleen damage with visceral fat accumulation. The data obtained are useful for the governmental authorities to legislate and implement regulations concerning the use and the production of this kind of material that might be hazardous to the living beings, as well as to the environment.
