titanium dioxide nanoparticles: a risk for human health

The inhalation of titanium dioxide nanoparticles, which results in exposure of the consumer's lungs to TiO 2 nanoparticles, has been assessed by the SCCS as a health concern (SCCS/1516/13; SCCS/1583/17). TiO2 NPs possess different physicochemical properties compared to their fine particle (FP) analogs, which might alter their bioactivity. Another matter of concern is that titanium dioxide is an ingredient in food coloring... and the foods with the highest content are candy and gum. A Monte Carlo analysis found that children have the greatest exposure because of high titanium content in sweets. Personal care products such as toothpastes and sunscreens often contain titanium too. Potential risks to human health, SCENIHR Preliminary Opinion (see title above), 29 Mar. Mini Rev Med Chem. Dhandapani P, Maruthamuthu S, Rajagopal G. Bio-mediated synthesis of TiO 2 nanoparticles and its photocatalytic effect on aquatic biofilm. However, the European Food Safety Authority, or EFSA, reevaluated the assessment in 2021 to consider the impact of nanoparticle sizes of titanium dioxide. Results We conducted … The classification as bio-inert material has given the possibility to normal-sized (>100 nm) titanium dioxide particles (TiO2-NPs) to be extensively used in food products and as ingredients in a wide range of pharmaceutical products and cosmetics, such as sunscreens and toothpastes. Titanium dioxide in nanoparticle form (TiO2-NP) is used in many industrial and commercial applications. … In the field of nanomedicine, intravenous injection can deliver TiO 2 nanoparticulate carriers directly into the human body. Titanium dioxide (TiO 2 ) has been reported to induce adverse … The possible risk to health after consuming food containing nanoparticles has been poorly explored but it is supposed that the toxicity of nanoparticles depends on their size, morphology, rate of migration and amount consumed. Titanium dioxide white pigment consists of particles of various sizes, from which a fraction is in the nano range (<100 nm). SR History: Titanium (Ti) has been used in dental and medical products due to its strength, light . 2 files. Nano-titanium-dioxide: challenges for human health risk assessment CAS Article Google Scholar Peters RJ, van Bemmel G, Herrera-Rivera Z et al (2014) Characterization of titanium dioxide nanoparticles in food products: analytical methods to define nanoparticles. Food grade titanium dioxide (TiO 2) has been widely used as a food additive in the food industry.Compared to TiO 2 bulk particles, TiO 2 nanoparticles (TiO 2 NPs) has even more advantages on application. Effects of Titanium Dioxide Nanoparticles on Cell Growth and … Chen et al. Some studies have seen the accumulation of absorbed TiO 2 NPs in the lungs, liver, kidneys, spleen, heart, and central nervous system (Grande & Tucci, 2016; Younes et al., 2015). Recently, the EFSA (European Food Safety Authority) and the Panel on Food Additives and Flavorings (FAF) concluded E171 is not safe as food additive. In light of the data provided and of the possible classification as Carcinogen Cat. Titanium dioxide nanoparticles pose a greater risk. The potential health effects of TiO2NPs on the neurodevelopmental process should be seriously concerned in health risk assessment, especially for the pregnant women who are susceptible to the …
