Titanium Dioxide Nanoparticles Aggravated the Developmental Neurotoxicity of Ammonia Nitrogen on Zebrafish Embryos.

ABSTRACT: Total ammonia nitrogen (TAN) is a common and potent neurotoxic pollutant in aquatic environments. Due to their strong adsorption capacity, titanium dioxide nanoparticles (n-TiO₂), a widely used engineered material, can induce combined toxicity with multiple pollutants. However, the combined neurotoxicity of n-TiO₂ and TAN and its underlying mechanisms remain unclear. In this study, zebrafish embryos were exposed to TAN (0, 0.1, 1, 10 mg/L) and n-TiO₂ (100 µg/L) individually or in combination for 120 h. The results indicated that co-exposure to n-TiO₂ and TAN significantly increased the bioaccumulation of TAN in zebrafish embryos compared to TAN alone. Consequently, this led to exacerbated neurotoxicity, manifested as developmental impairments and
