RESOURCES. Titanium dioxide nanoparticles (TiO2-NPs) are widely used, and humans are exposed through food (E171), cosmetics (e.g., toothpaste), and pharmaceuticals. The oral and gastrointestinal (GIT) tract are the first contact sites, but it may be ...
13 Απρ 2019 · This paper gives a review of previous studies concerning the effects of exposure to TiO2 NPs on a living organism (human, animal). This information is necessary in order to demonstrate potential toxicity of inorganic nanoparticles on human health.
26 Ιαν 2021 · However, many studies proved that TiO2 NPs has more side effects . These nanoparticles may cause immunological and pathological changes after accumulation and can induce hepatic injury by altering biochemical parameters of serum (ALT, LDH, and BUN) depending on the amount and size of particles .
15 Απρ 2013 · Sub-acute toxicity studies last for a maximum of 4 weeks (28 days), sub-chronic toxicity studies for a maximum of 13 weeks (90 days) and chronic toxicity studies last longer than 4 months. The toxicity of TiO 2 NPs will be discussed in terms of these types of studies.
The extent and type of cell damage strongly depend on chemical and physical characteristics of TiO2-NPs, including size, crystal structure and photo-activation. In this mini-review, we would like to discuss the latest findings on the adverse effects and on potential human health risks induced by TiO2-NPs exposure.
Due to an increasing scope of applications, the exposure of humans to nanoparticles (NPs) is inevitable. A number of studies revealed that after inhalation or oral exposure, NPs accumulate in, among other places, the lungs, alimentary tract, liver, heart, spleen, kidneys and cardiac muscle.
Titanium dioxide nanoparticles (nano-TiO<sub>2</sub> ) are widely used in consumer products, raising environmental and health concerns. An overview of the toxic effects of nano-TiO<sub>2</sub> on human and environmental health is provided.
