PCDDs, PCDFs, and PCBs co-occurrence in TiO2 nanoparticles
| Abstract | In the present study, we report on the co-occurrence of persistentorganic pollutants (POPs) adsorbed on nanoparticular titanium dioxide(TiO2). We report on the finding of polychlorinated dibenzodioxins(PCDDs), polychlorinated dibenzofurans (PCDFs), and polychlorinatedbiphenyls (PCBs) on the surface of commercially available TiO2nanoparticles, being formed during the fabrication process of the TiO2.Thereby, the samples comprise PCBs with higher congener numbers or, inthe absence of PCBs, a high concentration of PCDDs and PCDFs. This newclass of POPs on an active catalytic surface and the great range ofapplications of nanoparticular TiO2, such as in color pigments,cosmetics, and inks, give rise to great concern due to their potentialtoxicity. |
