[Multiyear monitoring of the ecological status of industrial zones of Moscow using a test line of Drosophila melanogaster].
For 12 years, recombination rate was assessed in Drosophila melanogaster males exposed on a thermoelectric power station (TPS) of Moscow. In 1994, experiments were also carried out on another Moscow TPS for comparison. The recombination frequency in exposed males was two- or threefold higher than in the control sample. Recombination frequencies observed in different years did not significantly differ from each other. Likewise, no significant difference was observed for the results obtained on two TPSs. A dramatic increase in recombination frequency in flies exposed on TPS was considered as an adequate response to high concentrations of effective mutagens discharged by TPS.
