Mineral sunscreens like zinc oxide (white noses on lifeguards!) and titanium dioxide do a great job protecting your skin from sun but are messy and leave a white smear all over your body. Some companies have started marketing micronized or nanoparticle formulations of these sunscreens which blend into the skin invisibly. Some people have expressed concern about these particles making it into the bloodstream and causing harm. Researchers at NC State surveyed the public on 23 public health risks including this issue along with Xrays, smoking and obesity and more. People surveyed said they were not worried about nanotechnology compared to other issues. Research still needs to be done on this issue but maybe people prefer the benefits of nanotechnology and will tolerate the risk?

The paper, “Comparing nanoparticle risk perceptions to other known EHS risks,” is forthcoming from the Journal of Nanoparticle Research. The paper was co-authored by Berube and Binder; Jordan Frith and Christopher Cummings, Ph.D. students at NC State; and Dr. Robert Oldendick of the University of South Carolina. The research was funded by the National Science Foundation. More
