microfine titanium dioxide suppliers

There are several factors that can influence the cost of titanium dioxide from suppliers. One of the main factors is the availability of raw materials, specifically titanium ore. The cost of extracting and processing titanium ore can fluctuate, which can in turn affect the cost of titanium dioxide. Suppliers must also take into consideration the cost of energy and other resources needed for the production of titanium dioxide, such as labor and equipment.

In vitro, in the hemocytes of the marine mussel Mytilus hemocytes, suspension of TiO2 NPs (Degussa P25, 10 μg/ml) stimulated immune and inflammatory responses, such as lysozyme release, oxidative burst and nitric oxide production. Vevers and Jha demonstrated the intrinsic genotoxic and cytotoxic potential of TiO2 NPs on a fish-cell line derived from rainbow-trout gonadal tissue (RTG-2 cells) after 24 h of exposure to 50 μg/ml. Reeves et al. demonstrated a significant increase in the level of oxidative DNA damage in goldfish cells, and suggested that damage could not repaired by DNA repair mechanisms. Another suggestion from the mentioned study was that hydroxyl radicals are generated also in the absence of UV light. It has been shown that fish cells are generally more susceptible to toxic/oxidative injury than mammalian cells.
