In a 2016 study published in Scientifica (Cairo), Egyptian researchers examined the effects of titanium dioxide nanoparticles on the organs of mice by orally administering the food additive daily, for five days. The results showed that the exposure produced “mild to moderate changes in the cytoarchitecture of brain tissue in a time dependent manner.” Furthermore, “Comet assay revealed the apoptotic DNA fragmentation, while PCR-SSCP pattern and direct sequencing showed point mutation of Presenilin 1 gene at exon 5, gene linked to inherited forms of Alzheimer’s disease.” The researchers wrote: “From these findings, “the present study concluded that TiO2NPs is genotoxic and mutagenic to brain tissue which in turn might lead to Alzheimer’s disease incidence.”

The production of lithopone is associated with several environmental concerns, including air and water pollution. Zinc sulfide ore mining can lead to soil erosion and habitat destruction, while sulfuric acid leaching and calcination processes can release pollutants into the air and water. To address these issues, many Chinese lithopone factories have implemented environmental protection measures such as wastewater treatment and emission reduction technologies.

sufiicient sulphuric acid to extract up to 95 per cent or more, of the titanium oxide prescut. This extraction is carried on so that the resulting product, after the addition of the required amount of sulphuric acid, is in the form of a dry powdered .mass, in which approximately 95 per cent of the titanium is in a soluble form. Th dry powdered mass is thenextractedin suitable leaching tanks with water, whereby a solution of approximately 70 grams of sulphuric acid and 100 grams of titanium oxide to the liter, is obtained.

The functions of lithopone in coatings: it is mainly used in water-soluble coatings (water-soluble coatings, wall coatings), blending paint as topcoat (with reasonable high paint adhesion, excellent circulation and long storage capacity), all kinds of methyl cellulose paint (can be applied to wooden furniture such as furniture and small toys) Alkali resistant coatings based on isopropyl titanate vulcanized rubber and polyurethane materials. Also because of its excellent paint adhesion, aging resistance, acid resistance and leveling, for the production of lacquered cloth color pigments look better. It can also be used in electrophoretic coating and optical guiding system software.
