Evaluation of occupational exposure to TiO2 nanoparticles: microwave-assisted acid digestion method on air membrane filters

Titanium dioxide (TiO2) nanoparticles have been extensively used in various industrial sectors and applications, including cosmetics, catalysts, food additives, inks, paints, and coatings. However, the International Agency for Research on Cancer (IARC) has classified TiO2 nanoparticles as a potent...
