Rhetorical gamesmanship in the nano debates over sunscreens and nanoparticles

Communication of risk profiles associated with sunscreens incorporating nanoparticles has been challenging when some communicators shift risk profiles from highly problematic nanoparticles to others, which are much less problematic. This article vets a popular publication from a civic advocacy group that cited scientific research papers to make environmental health and safety claims. The phenomenon of risk profile shifts is demonstrated by re-examining the scientific articles being cited. In addition, the authors for correspondence for each of the articles cited were interviewed via email and their comments about the claims made are included.
