title: Clastogenicity of furans found in food.
abstract: Cultured Chinese hamster ovary (CHO) cells were exposed for 3 h to furan and 6 furan derivatives (furfural, furfuryl alcohol, 5-methyl furfural, 2-methyl furan, 2,5-dimethyl furan and 2-furyl methyl ketone). Each of the 6 furan derivatives induced a relatively high frequency of chromatid breaks and chromatid exchanges in the absence of a liver microsomal activation preparation. The response of the furans to the addition of an S9 mixture differed. The clastogenic activities of 5-methyl furfural, 2-furyl methyl ketone, furfural and furfuryl alcohol were increased, whereas that of 2-methyl furan and 2,5-dimethyl furan were significantly decreased. Furan itself showed a clastogenic activity only in the presence of an S9 mixture.
