Figure 3.

Percentage of DNA fragmentation in zebrafish blood cells (ordinate) after 7 days of exposure (A) and after 14 days of exposure (B) to TiO₂ NPs alone, lincomycin alone, and TiO₂ NPs and lincomycin in combination (abscissa). The dark bars are the negative control (NC); the white bars are 10 μg/L TiO₂ NPs treated specimens (TiO₂ NPs); the striped bars are 100 mg/L lincomycin treated specimens (lincomycin); and the dotted bars are 10 μg/L TiO₂ NPs + 100 mg/L lincomycin treated specimens (TiO₂ NPs + lincomycin); * p ≤ 0.05 in comparison with the NC.
