The treatment of urban wastewater causes changes in the rivers’ flora and fauna
Partially managing rivers to make them cleaner only by reducing the amount of phosphorus and phytoplankton, can entail undesirable changes throughout the ecosystem due to a nutrient imbalance. This is the main result of a study by researchers Carles Ibáñez at IRTA and Josep Peñuelas, CSIC researcher at CREAF, which was published by Science.
