Studies on aluminum nanoparticles and titanium nanoparticles indicate that they are explosion hazards. [ 5 ] : 17–18 One study found that the likelihood of an explosion but not its severity increases significantly for nanoscale metal particles, and they can spontaneously ignite under certain conditions during laboratory testing and handling.
Andrew Maynard, director of Risk Science Center at the University of Michigan, rejected the supposed danger from use of titanium dioxide in food. He says that the titanium dioxide used by Dunkin' Brands and many other food producers is not a new material, and it is not a nanomaterial either. Nanoparticles are typically smaller than 100 ...
Titanium dioxide has been found to be toxic to plants and small organisms such as worms, nematodes, and small arthropods. [22] The toxicity of TiO 2 nanoparticles on nematodes increases with smaller nanoparticle diameter specifically 7 nm nanoparticles relative to 45 nm nanoparticles, but growth and reproduction are still affected regardless of ...
Ultra-processed foods: The hidden dangers behind the labels. WGN Chicago. Dina Bair. January 7, 2025 at 5:40 PM. There is a growing and troubling trend when it comes to our diet. More than half of ...
In the study, rats that ingested titanium dioxide every day showed signs of a flared-up immune systems and pre-cancerous lesions. (Don’t miss these other 8 cancer-causing foods you should stop ...

Regulatory bodies such as the United States Environmental Protection Agency and the Health and Consumer Protection Directorate of the European Commission have started dealing with the potential risks of nanoparticles. The organic food sector has been the first to act with the regulated exclusion of engineered nanoparticles from certified ...
Titanium dioxide nanoparticles imparts what is known as the self-cleaning effect, which lend useful water-repellant and antibacterial properties to paints and other products. Zinc oxide nanoparticles have been found to have superior UV blocking properties and are widely used in the preparation of sunscreen lotions, [ 171 ] being completely ...
