In this study, the mutagenic and recombinogenic effects of fungicides; cyprodinil and fludioxonil, widely used in agricultural regions, were investigated using the somatic mutation and recombination test (SMART) in Drosophila wings. The viability and proliferation effects also tested on a human immortalized embryonic kidney HEK293 cells which is at the early stage of carcinogenesis were also examined with MTT and trypan-blue exclusion assays. For the SMART assay, two different crosses were used: a standard (ST) and a high-bioactivation (HB) cross, involving the flare-3 (flr(3)) and the multiple wing hairs (mwh) markers. The HB cross involved flies characterized by an increased cytochrome P-450-dependent bioactivation capacity, which permits the more efficient biotransformation of promutagens and procarcinogens. In both crosses, the wings of the two types of progeny, inversion-free marker heterozygotes and balancer heterozygotes, were analyzed. The results show that both fungicides were recombinogenic at the tested highest concentration, on the wing cells of Drosophila. Furthermore, neither fungicide affected the proliferation rate of the HEK293 cells but both induced cell death at high concentrations.
