Fig. 2From: PIG-A gene mutation as a genotoxicity biomarker in polycyclic aromatic hydrocarbon-exposed barbecue workersFrequencies of Micronuclei (MN), nucleoplasmic bridges (NPB) and nuclear buds (NBUD) in PAH-exposed workers (N = 70) and controls (N = 56). Black line: median with interquartile range. Among the PAH-exposed workers, MN, NPB, and NBUD frequencies were 3.06 ± 2.07 ‰, 0.47 ± 0.55 ‰, and 1.38 ± 1.02 ‰, respectively. Among the control subjects, MN, NPB, and NBUD frequencies were 1.46 ± 0.64 ‰, 0.47 ± 0.48 ‰, and 0.70 ± 0.60 ‰, respectively. **Significant differences P < .01Back to article page
