Evaluación de la calidad de agua de arroyos de la provincia de Entre Ríos

The objective was to evaluate the quality of water from basin collector streams in the geographical departments of Federal, Federación, Feliciano and Diamante related to dams for crop irrigation under the hydrological situation of low water. Twelve stream environments were sampled including an inventory of plant life. Water samples were taken for chemical-physicalanalysis and for carrying out two bioassays: Allium test and Lactuca sativaseedgermination. Root length and germination index, variables recorded in both bioassays, were analyzed using Dunnet’s test. Streams from Central North of the Entre Rios Provincepresented low sodium adsorption relation (RAS) values (
