TiO2 Nanoparticles in the Environment
Products coated in titanium dioxide nanoparticles (nTiO₂) shine pure white. So since the 1990s manufacturers have added the chemicals to a wide range of consumer products, such as cosmetics, paints, sunscreens, and even foods. Now nTiO₂ often discharges into open waterways through treated sewage effluent. A new study reports that this nanomaterial can stress photosynthetic organisms, which could lead to the disruption of nitrogen and carbon cycles in aquatic ecosystems (Environ. Sci. Technol., DOI:
