Genotoxicity of 2,4,6-trichlorophenol in V79 Chinese hamster cells

|January 1, 1992
Abstract:
The genotoxicity of the rodent carcinogen 2,4,6-trichlorophenol (TCP) was studied without exogenous metabolic activation in V79 Chinese hamster cells. TCP did not induce mutation at the hprt locus to 6-thioguanine resistance or structural chromosome aberrations. However, it produced statistically significant, dose-related increases in hyperdiploidy and micronuclei. From these results it appears that TCP causes chromosome malsegregation as its major mode of genotoxic action.
