Time-Related Alteration of Aqueous-Phase Anthracene and Phenanthrene Photoproducts in the Presence of TiO₂ Nanoparticles.

ABSTRACT: Polycyclic aromatic hydrocarbons (PAHs) and titanium dioxide (TiO₂) nanoparticles (NPs) are photoactive environmental pollutants that can contaminate aquatic environments. Aqueous-phase interactions between PAHs and TiO₂-NPs are of interest due to their emerging environmental relevance, particularly with the deliberate application of TiO₂-NPs to remediate pollution events (e.g., oil spills). Our objective was to investigate anthracene (ANT) and phenanthrene (PHE) photoproduct formation and transformation following ultraviolet A (UVA) irradiation in the presence and absence of TiO₂-NPs. ANT and PHE solutions were prepared alone or in combination with TiO₂-NPs, UVA-irradiated, and either exposed to larval zebrafish or collected for chemi
