The toxicity study of a systemic fungicide: artea 330 EC on the physiology and the respiratory metabolism of the tadpole (Rana saharica).


PMID 18399440

Abstract

The intensification of the cereal cultures accompanied by the apparition of damaging illnesses for these cultures. These illnesses are Largely imputed to mushrooms micro and macroscopic chatty of important damages at wheat, the barley and of none targeted other animal species. The products used against these illnesses are called: Fungicides. In our work, we are interested in the survey of the effects of a systemic fungicide: the ARTEA 330 EC introduces newly in Algeria, on some physiological and metabolic parameters of a biologic model: the tadpole The exhibition of the populations of tadpoles to the different concentrations of the ARTEA 330 EC provokes a fall very important of the middleweights of the tadpoles treated. This one is reduced of meadows of 80% to the strongest concentration of ARTEA 330 EC. It is some in the same way for the reduction of the middle size of the tadpoles where one records a reduction of 25%. Concerning the percentage of mortality gotten, we observe that the one is here from 100% to the strongest concentration of ARTEA 330 EC. The breathing of the tadpoles treated by fungicide is disrupted strongly and to the strongest concentration, this one is inhibited completely. The gotten results show that the exhibition of the populations of tadpoles to the different concentrations of fungicide disrupts the physiological parameters strongly and inhibit the respiratory metabolism. A phenomenon of detoxication seems to intervene; it is put in evidence by a stimulation of the synthesis of the proteins.
