The subject presented in this paper looks at the evaluation of the pollution load and toxicity of wastewaters used in irrigation and pollution measurements particularly the pollutants toxics as well as trace metals.
The evaluation of the level of pollutants and following their kinetic along the river to determine the load of pollutants in the soil and plants during the irrigation by wastewaters in order to evaluate the vulnerability of the underground of the waters to the pollution. The final step of our research is based on the proposal of a model detoxification of trace metals in wastewater by precipitation total of these items by using parameter pH, using a database of Hartinger and Weiner [8].
