In the paint and coating industry, barium sulfate's superfine particles provide opacity, gloss, and improved flow characteristics. Its non-toxicity also makes it a safe option for use in paints designed for children's toys and other products where safety is paramount Its non-toxicity also makes it a safe option for use in paints designed for children's toys and other products where safety is paramount Its non-toxicity also makes it a safe option for use in paints designed for children's toys and other products where safety is paramount Its non-toxicity also makes it a safe option for use in paints designed for children's toys and other products where safety is paramountcheap barium sulphate superfine. In the plastics and rubber industries, it acts as a reinforcing agent, boosting mechanical strength and thermal stability without significantly affecting the overall cost.

It should also be considered that due to the low pH in the stomach, the increased dissolution of the TiO2 particles may increase its bioavailability and may facilitate the entry of titanium ions into the blood circulation. Despite the relatively large consumption of TiO2 as a food additive, no studies on the effect of pH on its absorption and bioavailability have been found in the literature. This can be attributed to a general belief that TiO2is completely insoluble. However, this is not completely true, as TiO2 particles show a certain degree of solubility.

Freshwater algae show low-to-moderate susceptibility to TiO2 exposure, with more pronounced toxic effects in the presence of UV irradiation. It has also been shown that nano-sized TiO2 is significantly more toxic to algae Pseudokirchneriella sub-capitata than submicron-sized TiO2. Hund-Rinke and Simon  reported that UV irradiated 25 nm TiO2 NPs are more toxic to green freshwater algae Desmodesmus subspicatus than UV irradiated 50 nm particles, which is in agreement with Hartmann et al. UV irradiated TiO2 NPs also inactivated other algae species such as AnabaenaMicrocystisMelsoira and Chroococcus. It was demonstrated that smaller particles have a greater potential to penetrate the cell interior than submicron-sized particles and larger aggregates. Studies have shown that the amount of TiO2 adsorbed on algal cells can be up to 2.3 times their own weight.
