A Rutgers study reveals that consumer spray residue can activate nanoparticles in the air, potentially contributing to indoor air pollution.

A Rutgers study in the journal Science of the Total Environment finds that consumer spray residue can activate nanoparticles in the air, potentially contributing to indoor air pollution. When people walk through rooms where a nanoparticle-containing product has been sprayed, residual specks are stirred off surfaces, projecting them up to five feet. Children on the floor are more affected than adults.
