• Sommario/riassunto: Pollution of freshwater resources becomes an issue in virtually every country undergoing an industrialization process. While the main emphasis has been for many years on lakes due to their limited capacity of self-renewal, streams and rivers attract increasing attention due to their importance for agriculture, fisheries, drinking water reserves and as feeder of freshwater lakes and reservoirs. There are many factors influencing the ecology of streams, only some of them relating to direct anthropogenic influences and it is important to have reliable long term data on natural occurring variat
