The impact of flucycloxuron on eggs weight kinetic and hematological parameters of chicken (Gallus domesticus).

The struggle against the harmful bugs of culture is intensified, and several products are appeared every year without the knowledge how to control their effects on environment and especially on being life. The introduced chemical products in nature are generally, the synthesis products witch are the pesticides. Our study consist the impact mechanism of a pesticides (FCX) on other biological model than harmful bugs, this biological model is a vertebrate model witch is the domestic chicken eggs (Gaollus domesticus). The toxicity of Flucycloxuron reviewed across the eggs weight kinetic accompanied with embryonic hematological parameters, in ovo and after hatching. The tested concentrations of pesticide are 1, 10 and 20 microg/egg injected at first day of incubation. Eggs treatment by three concentrations of pesticides, disturbs the studied parameters, where we observe that the pesticide inhibit the nutriment transformation, translated by eggs decreased weight kinetic according to the control, also the FCX affect the shell weight and cause the alteration of shell integrity. Hematological parameters show a clear impact of the pesticide at the lowest concentration (1 microg/egg). The obtained results confirm that the chosen biological model is good bio-indicator for eventual pollution and they are not far from pesticides toxicity.

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

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.
