Resumo: | The impact of environmental factors on aneuploidy level in the oyster Crassostrea gigas was studied with experiments in controlled conditions which exposed adult and juvenile oysters to different pollutants (atrazine, a herbicide, and cadmium, a heavy metal) frequently found in Marennes-Oléron Bay. A positive correlation between atrazine concentration and aneuploidy in C. gigas was observed. Moreover, the impact of atrazine on aneuploidy level persisted in time both within and between generations, demonstrating the influence of an environmental pollution on this phenomenon. On the other hand, the aneuploidy level of C. gigas was not influenced at the cadmium concentrations tested. Significant differences in aneuploidy levels were observed in oysters originating from the same families on different sites, and in wild oysters collected over time, suggesting that both site and season affect aneuploidy.
