Descripción
The fungicide tebuconazole (TBZ) has been used to prevent terrestrial fungi in agroecosystems, but it can also induce negative effects to non-targeted aquatic organisms, such as plants. The aim of the present work was to evaluate the potential cyto- and genotoxicity of TBZ in the aquatic macrophyte Bidens laevis, exposed to a range of concentrations of 0.1–100 μg/L. Mitosis in root tips were analyzed showing decreased mitotic index and an increase of chromosomal aberrations at 10 and 100 μg/L. The regression of TBZ concentration vs. aneugenic aberrations was significant, indicating the mechanism of genotoxicity. The specific growth rate (Gr) for total length decreased in plants exposed to 0.1, 10 and 100 μg/L. Gr for root decreased in plants exposed at 0.1 and 10 μg/L, reaching a maximum percent inhibition root growth rate (Ir) of 68.8%. These results show that TBZ resulted cyto- and genotoxic to B. laevis at environmentally relevant levels.
