In general, the nanosilver particles are firmly embedded in the paint. Pristine nanoparticles are rarely released. Sandblasting experiments with nano-enhanced paints demonstrated that it is possible to remove some nanomaterials from the applied paint albeit only to a very small extent. Once particles are being released, they immediately get in contact with other particles or form agglomerates. The conclusion of no aerosolised nanoparticles being present has been confirmed by other studies as well. Small amounts of silver nanoparticles are non-hazardous for humans. Some environmental organisms like fish are more sensitive to silver. Since current studies showed that the estimated amounts of released nanosilver were below detection limit, it can be assumed that these nanoparticles present no risk for the environment.
