I understand that the EPA is reluctant to allow the use of nanoparticles in coatings, due to their tendency to persist in the environment. What is the real risk, and how can the nanocoating industry address it?

From John Becker IV of Creative Material Technologies, Ltd. on November 13, 2019:
The persistence of nano-particles in the environment, coupled with their innate ability, due to their nano-scale size, to pass through the skin barrier and perhaps even the blood-brain barrier should be of real concern. Fortunately, the solution to this problem and the innate processing problems of nano-particles, including reagglomeration, poor shelf life of dispersions, and poor redispersability, are found in the same place. That is to not allow the nano-particles to be placed interstitially within a polymer but tied to the polymer itself as has been accomplished. In this way the nano-particle takes on the environmental and health profile of the polymer and becomes a much more "friendly" material.
