Non-genotoxic Mode of Action: distribution of classified abstracts for three chemicals: 1,3-butadiene, genistein and formaldehyde.
Figure 11.
Comparison of four known genotoxic (left) and four known nongenotoxic (right) chemicals. (b–c) show the distribution in the genotoxic MOA part, (d–e) show the distribution in the nongenotoxic MOA part.
The genotoxic chemicals are 1,3-butadiene, 4-aminobiphenyl, dibenzo[a,l]pyrene and ethylene oxide; the nongenotoxic chemicals are TCDD, PCB126, PCB153 and pentachlorodibenzofuran. * indicates statistically significant differences (, Wilcoxon rank sum test).
