titanium dioxide gravimetric analysis factory. By continuously monitoring the amount of titanium dioxide present in samples, the factory can identify any deviations from the expected values and take corrective actions to maintain the quality of the products.Fig. 5. ROS values (Abs of NBT) in samples of MSSA treated with A: 0.2 mg/mL P25TiO2NPs; B: 0.02 mg/mL P25TiO2NPs; C: 0.2 mg/mL VitaminB2@P25TiO2NPs; D: 0.02 mg/mL VitaminB2@P25TiO2NPs after 3 h of irradiation (red) and 6 h (blue). SD < 0.20 and p < 0.05 between C-D and A-B.
Available studies in humans and postmortem analysis of tissues suggested that the oral bioavailability of titanium dioxide in humans is very low. JECFA noted that there are currently no epidemiological studies that allow any conclusions to be drawn with respect to an association between dietary exposure titanium dioxide and human health effects.
A 2022 review on past studies of titanium dioxide and rat lung cancer, for instance, said the original study was under extreme conditions and its effects were not replicated in other animal species. Additionally, the review concluded that the few studies which did directly focus on titanium dioxide's impact on humans did not end up showing any increased cancer risk.
