anatase type tio2 manufacturers

Zhu et al. were the first to provide evidence that TiO2 NPs (21 nm) can transfer from daphnia to zebrafish by dietary exposure. Hence, dietary intake could be a major route of exposure to NPs for high trophic level aquatic organisms. Ecological research should therefore focus, not only on the concentration of NPs in the environment, but also on its bioconcentration, bioaccumulation and biomagnification. In addition it has been shown that TiO2 NPs can increase accumulation of other environmental toxicants: enhanced accumulation of cadmium (Cd) and arsenic (As) was found in carp in the presence of TiO2 NPs. The strong adsorption capacity for Cd and As was explained by the large specific surface area and strong electrostatic attraction of TiO2 NPs that contribute to facilitated transport into different organs.

The production of titanium dioxide traditionally involves processes that can be energy-intensive and potentially harmful to the environment. However, leading manufacturers have embraced cleaner technologies such as the chloride process, which yields high-purity TiO2 while significantly reducing waste and emissions. By utilizing this method, factories can minimize the release of contaminants and conserve resources more effectively than older techniques.
