Abstract. Titanium dioxide, first manufactured a century ago, is significant in industry due to its chemical inertness, low cost, and availability. The white mineral has a …

Introduction. Titanium dioxide (titania, TiO 2) is chemically inert, semiconducting material that also exhibits photocatalytic activity in the presence of light with an energy equal to or higher than its band-gap energy.These characteristics offer a wide range of applications. For these reasons, and because of the relatively low price of the …

Titanium dioxide (TiO 2) as a photocatalyst has been ubiquitously studied for environmental applications.Though, readily available, nontoxic, and environmentally friendly; lower efficiency, less energy harvesting within the UV–Vis range with the ease of photogenerated charge recombination is still a concern for its full-scale deployment as a …

Although titanium dioxide (TiO 2) is the most widely used pigment in plastics, there is limited quantitative information available for consumer goods and …

The characterization of MNMs with analytical tools to comprehend their fate and effect on the ecosystem is hence of great importance for environmental risk assessment. We herein report, for the first time, the investigation of physicochemical transformation processes during artificial wastewater treatment of silver (Ag-NPs) and titanium dioxide ...

Titanium dioxide (TiO 2) nanoparticles (NPs) are manufactured worldwide in large quantities for use in a wide range of applications.TiO 2 NPs possess different physicochemical properties compared to their fine particle (FP) analogs, which might alter their bioactivity. Most of the literature cited here has focused on the respiratory system, …

Therefore, as part of the research project "Assessment of the emission behaviour of nanomaterial-containing waste in thermal treatment plants" funded by the German Federal Environment Agency, we investigated the fate of nano titanium dioxide (nTiO 2) during thermal waste treatment. One main objective of the project was to …

In the agroecosystem, titanium dioxide nanoparticles are used in fertilisers, pesticides, remediation and bio-sensors. These applications lead to a pervasive and inevitable distribution of TiO2 NPs in the agroecosystem. It is very important to understand the behaviour of TiO2 NPs in the soil and to assess their impact on the agroecosystem. …

Although titanium dioxide (TiO2) is the most widely used pigment in plastics, there is limited quantitative information available for consumer goods and environmental samples. Moreover, and despite its photocatalytic activity, the potential impacts of TiO2 on the behaviour and fate of environmental plastics has received little attention.

Titanium dioxide (TiO 2) is widely used in food products, which will eventually enter wastewater treatment plants and terrestrial or aquatic environments, yet little is known …

All TiO 2 particles were mainly transported by microfold (M) cells, but also by intestinal tight junction. These findings will be useful for TiO 2 application in the food industry and predicting its potential toxicity. …

Preparation of samples. Titanium dioxide samples were prepared in three ways and used in the sample. Firstly, an industrial homogenizer (manufactured by AICA company with the power of particles up ...

Titanium Dioxide may cause cancer in humans. Long-term exposure to titanium dioxide dust may result in mild fibrosis (scarring of the lungs). Aggravation of Pre-existing Conditions: Persons with pre-existing lung disease may be more susceptible to the effects of this substance.

Titanium dioxide is commonly used as a food additive to enhance color and taste. It is also present in food packaging and cosmetic products like sunscreen. While titanium dioxide is FDA approved for general use in food, more research is needed to determine its effects on humans. In animals, it has been shown to have gastrointestinal …

Titanium dioxide is the naturally occurring oxide of titanium. It's a white powder that's widely used as a whitening agent, UV filter, and thickener in many consumer products. Because it's naturally bright and reflective, it's …

Soils are facing new environmental stressors, such as titanium dioxide nanoparticles (TiO2-NPs). While these emerging pollutants are increasingly released into most ecosystems, including ...

Titanium dioxide (TiO 2) is widely used in food products, which will eventually enter wastewater treatment plants and terrestrial or aquatic environments, yet little is known about the fraction of this TiO 2 that is nanoscale, or the physical and chemical properties of TiO 2 that influence its human and environmental fate or toxicity. Instead of analyzing TiO 2 …

Previously, we found that whey proteins form biomolecular coronas around titanium dioxide (TiO 2) nanoparticles.Here, the gastrointestinal fate of whey protein-coated TiO 2 nanoparticles and their interactions with gut microbiota were investigated. The antioxidant activity of protein-coated nanoparticles was enhanced after simulated digestion.

Along their life cycle from production to disposal, TiO2-NPs can be released in the environment, especially the soil through various pathways, such as agricultural amendments of biosolids. In vitro studies demonstrated TiO2-NPs toxicity on microorganisms but data are still scarce on the fate and ecotoxicity of these …

The fate determination and quantification of E171 TiO 2 in commercial foods were carried out based on the analytical procedure developed using simulated foods. …

Titanium dioxide NM stock suspensions were prepared using Hombikat TiO 2 powder (Sachtleben Chemie , Duisburg, Germany). Hombikat TiO 2 has a low iso-electric point (pH ZPC ∼ 5.3 as estimated using a ZetaPALS instrument, Brookhaven Instruments, NY). The stock suspension was prepared by suspending 1 g of TiO 2 into 1 …

1. Introduction. Titanium dioxide nanoparticles (TiO 2-NPs) find their wide applications in architectural and industrial paints and coatings, plastics, paper, catalysts, ceramics, coated fabrics, floor covering, ink, food additives, toothpaste, and sun blocks (Chen and Mao, 2007; Jamkhande et al., 2019; Makul, 2020).Their global …
