Acute Toxicity of Intravenously Administered Titanium Dioxide Nanoparticles in Mice
BACKGROUND With a wide range of applications, titanium dioxide (TiO₂) nanoparticles (NPs) are manufactured worldwide in large quantities. Recently, in the field of nanomedicine, intravenous injection of TiO₂ nanoparticulate carriers directly into the bloodstream has raised public concerns on their toxicity to humans. METHODS In this study, mice were injected intravenously with a single dose o...
متن کاملToxicity and interaction of titanium dioxide nanoparticles with microtubule protein.
Titanium dioxide (TiO2) nanoparticles (NPs) are widely used in several manufactured products. The small size of NPs facilitates their uptake into cells as well as transcytosis across epithelial cells into blood and lymph circulation to reach different sites, such as the central nervous system. Different studies have shown the risks that TiO2 NPs in the neuronal system and other organs present. ...
متن کاملNasal and Pulmonary Toxicity of Titanium Dioxide Nanoparticles in Rats
In recent decades, titanium dioxide (TiO2) nanoparticles have been used in various applications, including paints, coatings, and food. However, data are lacking on the toxicological aspects associated with their use. The aim of this study was to assess the inhalation toxicity of TiO2 nanoparticles in rats by using inhalation exposure. Male Wistar rats were exposed to TiO2 nanoparticles for 2 we...
متن کاملEffective Utilization of Titanium Dioxide
For example, if Coating A has a contrast ratio of 0.920 and Coating B has a contrast ratio of 0.900, about all that can be said is Coating A has higher opacity than Coating B. We can say it is 0.020 higher, but it is not clear how to use this number to formulate Coating B to have equal hiding. Also, this is not helpful in deciding what to change in order to improve opacity. Fortunately, quantit...
متن کاملAcute toxicity of titanium dioxide nanoparticles in Daphnia magna and Pontogammarus maeoticus
Titanium dioxide nanoparticles (nTiO2) are the world's second most widely consumed nanomaterial and large quantities of this material enters the aquatic ecosystem annually. Therefore, understanding the effects of nTiO2 on aquatic organisms is very important. The present study used Daphnia magna as a model freshwater organism and Pontogammarus maeoticus as a brackish water organism to evaluate s...
