Figure 1.

The effects of single compounds and binary mixtures of CYN (0.5 µg/mL) and BPs (BPA, BPS, BPF, BPAF; 10 µg/mL) on the viability of HepG2 cells after 24 h (A) and 72 h (B) exposure, expressed in percentage of the solvent control (0.05% methanol and 0.04% DMSO = dotted line at value 1.0). PC is the positive control—etoposide ET (30 μg/mL). The lower dotted line in figure B denotes the average viability reduction by CYN. The asterisks (*) denote statistically significant difference between solvent control and treated cells (* p ≤ 0.05; ** p ≤ 0.01; **** p ≤ 0.0001).
