titanium dioxide anatase could trigger an environmental crisis

Nano-titanium dioxide, also known as titanium dioxide. Because of the high refractive index, superior absorption ability and excellent UV sterilization, deodorization, and antifouling properties, titanium dioxide anatase is often regarded as a photocatalyst and environmentally friendly additives and a plurality  PVC stabilizer worldwide Widely used. As for skin care products, food, white paint and other consumer goods and household production, the annual production capacity of up to millions of tons, and showed a rising trend.
Proved by experiments, titanium dioxide anatase atmosphere rich in nitrogen and oxygen can be formed on the surface of nano titanium dioxide photocatalytic reaction by nitrates and combined to form a mechanism to clarify the Metal stearate  theoretical calculation and analysis of nitrate. Excessive nitrates discharged into water bodies, the body will produce toxic, such as lead children “blue baby syndrome” can cause eutrophication and cyanobacteria outbreak, resulting in environmental pollution problems.
Photocatalytic formation of nitrate found in the photocatalytic reaction, remind people may have underestimated the potential environmental risks of extensive use of titanium dioxide. The chemical reaction on the one hand may Stearates  exacerbate the increasingly serious problem of nitrogen pollution, but it also provides a mild conditions and low cost method of producing nitrates new.
