No acute effects of nano-sized TiO2 were observed in Danio rerio (zebrafish) embryos. Exposure of rainbow trout to TiO2 NPs triggered lipid peroxidation, influence on the respiratory tract, disturbance in the metabolism of Cu and Zn, induction of intestinal erosion  and accumulation in kidney tissue. Linhua et al. exposed juvenile carp to 100 and 200 mg/ml of particles and TiO2 observed no mortality. However, the fish suffered from oxidative stress and pathological changes in gill and liver. In the infaunal species Arenicola marina, exposure to TiO2 NPs in sediment caused sub-lethal effects including decrease in casting rate and increase in cellular and DNA damage. Aggregated particles were visible in the lumen of the gut, but no uptake through the gut or the skin was observed.

In the paint industry, titanium dioxide serves as a critical component due to its excellent hiding power and durability. It enhances the coverage of paints and protects substrates from UV damage, extending the lifespan of coatings. In plastics, it not only provides color but also improves the strength and stability of the final product. In paper manufacturing, titanium dioxide contributes to higher opacity and printability, resulting in superior graphic arts products.

One commonly used method for determining barium in TiO2 is atomic absorption spectroscopy (AAS). This technique involves vaporizing the sample and then measuring the absorbance of light by barium atoms at a specific wavelength. AAS offers high accuracy and precision, making it suitable for both laboratory and industrial settings. However, it requires specialized equipment and trained personnel, which can increase costs and turnaround time.
