O impacto do triflumuron sobre o organismo-modelo zebrafish (Danio rerio)

Abstract

In the present study, we aim to evaluate the frequency of micronuclei and nuclear abnormalities in erythrocytes from zebrafish (Danio rerio), by the exposure of this species to different concentrations of triflumuron (Certero®), in acute (96 hours) and chronical (30 days) tests. In acute treatments the following concentrations of insecticide were used: 0,2 mL/L; 0,6 mL/L e 1,8 mL/L. In this tests there was complete fish mortality within 24 hours of exposure to the insecticide. In the chronicle treatment it was used the concentration of 0,2 mL/L. In this last test, there was no fish mortality before the end of the experiment, but through the statistical test it was verified that the triflumuron did not increase the frequencies of micronuclei and abnormalities in the blood cells of these animals.
