Children may have highest exposure to titanium dioxide nanoparticlesWashington DC (SPX) Feb 22, 2012 Children may be receiving the highest exposure to nanoparticles of titanium dioxide in candy, which they eat in amounts much larger than adults, according to a new study. Published in ACS' journal, Environmental Science and Technology, it provides the first broadly based information on amounts of the nanomaterial - a source of concern with regard to its potential health and environmental effects - in a wide range of consumer goods. In the study, Paul Westerhoff, Ph.D., and colleagues point o ... read more |
