DETERMINATION DE L'ORIGINE DES NITRATES DANS LA NAPPE DU CONTINENTAL INTERCALAIRE REGION ADRAR

Abstract

The purpose of this study is to provide the main geological and hydrogological characteristics of the groundwater to the stratified continental infill in the area of Adrar and as knowledge and identify the sources and the main causes of nitrate in the region. The importance of nitrate is the most efficient chemical pollutants in the inhabitants and when surplus nitrates resulting from agricultural fertilizers and animal residues, such as health problems such as mathemogglin disease and cancer. The results obtained after tests for several samples recorded a ratio of between 0,17 mg/l and 214 mg/l. For signal, this ratio should not exceed 50 mg/l.
