The scientific article "Multiple stressors determine river ecological status at the European scale: Towards an integrated understanding of river status deterioration" has been published. It has been found that almost two thirds of the observed changes in European freshwater biota can be directly attributed to human influences. Excess nutrients (nitrogen and phosphorus compounds), toxic substances (pesticides and other dangareous substances) and hydromorphological changes (changes in the dynamics, duration and frequency of high waters, prolonged hydrological droughts, water abstraction, channel regulations, narrowing of riverbeds, etc.) are almost equally negatively impacting rivers.
