A research study has reported that the level of exposure to titanium dioxide nanoparticles in children can be much higher than in adults, as children consume larger amounts of candy containing these nanoparticles.
The study by Paul Westerhoff and his colleagues provides the first comprehensive information on the amounts of titanium dioxide nanoparticles present in a wide variety of consumer products, from cosmetics to food coloring. The results of the study have been published in Environmental Science & Technology, a journal of the American Chemical Society.
The team found that children consume more titanium dioxide compared to adults, because sweets such as ice cream, marshmallows and candy contain the highest levels of these nanoparticles. The article mentions the names of the tested products and their titanium dioxide content. Westerhoff suggests that regulatory bodies should change their view of the titanium dioxide nanoparticles used in industrial processes and the colorants in some foods, as they are a potential source of risk to humans, animals and the environment.
