4 Νοε 2021 · The results demonstrate the strong effect of particle size on membrane disruption and leakage behaviors, especially indicating the cytotoxicity of nano-sized TiO 2 particles improved with decrease of particle sizes. Therefore, the use of TiO 2 NPs as a food additive has potential health risks.
Nanosized materials were present in all of the food-grade TiO2 samples, and transmission electron microscopy showed that samples 1-5 contained 35, 23, 21, 17, and 19% of nanosized primary particles (<100 nm in diam.) by no., resp. (all primary P25 particles were <100 nm in diam.).
18 Ιαν 2012 · This study quantifies the amount of titanium in common food products, derives estimates of human exposure to dietary (nano-) TiO 2, and discusses the impact of the nanoscale fraction of TiO 2 entering the environment. The foods with the highest content of TiO 2 included candies, sweets, and chewing gums.
We encounter titanium dioxide nanoparticles (TiO 2 NPs) throughout our daily lives in the form of food coloring, cosmetics, and industrial materials. They are used on a massive industrial scale, with over 1 million metric tons in the global market.
27 Οκτ 2020 · The presence of nanoparticles (NPs) in food-grade TiO 2 led several laboratories to investigate the possible occurrence of acute or chronic adverse effects following TiO 2 ingestion. However, no consensus has been currently reached on the impact of ingested TiO 2 on human health.
2 Φεβ 2012 · One study monitoring TiO 2 nanomaterials found the highest concentrations in river water to be directly downstream of a WWTP . TiO 2 nanomaterials removed from sewage through association with bacteria may still end up in the environment if the biomass is land applied.
11 Φεβ 2024 · Titanium dioxide (TiO 2) material is a widely used, odorless, white powder that finds applications in the pharmaceutical, food, and cosmetic industries (Dahl et al., 2014; Fattakhova-Rohlfing et al., 2014; Wang et al., 2014). Due to its stability and durability, it is insoluble in water, acids, alkalis, and most organic solvents.
