Figure 3.
Effect of various dihydroxylated PCB metabolites (100 μM) on polar oxidative DNA adduct levels following incubation with DNA (300 μg/ml) and CuCl2 (100 μM). Vehicle used was 0.5% ethanol. Adduct levels were determined as the mean of 3 to 4 replicates ± S.E. Asterick (*) indicates values significantly different from vehicle at P ≤0.05. Specific conditions are described in text.
