Apoptosis and DNA damage in erythrocytes of C. gariepinus. after 15-day exposure. Fish were exposed to CA (100 ng L⁻¹), PE-NPs (5 mg L⁻¹; 20–80 nm), or their combinations. (a) Representative fluorescence images of apoptotic erythrocytes (red circles) and non-apoptotic erythrocytes (yellow circles). (b) Percentage of apoptotic cells. (c–d) DNA damage assessed by comet assay (tail moment score) (scale bar = 50 μm). Data are shown as mean ± standard error (SE) (n = 6). **Statistical significance: *p < 0.05, ***p < 0.001; ns = non-significant.
