Nano-sized emission from commercially available paints used for indoor surfaces during drying

The results from the solvent-borne paint showed the highest concentration, with a mean concentration of 3.2·105 particles/cm3 and a maximum of 1.4·106 particles/cm3. This paint also had the smallest particle size distribution, with 9.31 nm particles as the most dominant particle size. The results from this study showed that the exposure to nanoparticles for the residents evaluated over a 7 or 28 day period was low and that interior paints are probably not very important when it comes to identifying products that release nano-particles into indoor environments.
