The fluctuations of the most important water quality parameter (dissolved oxygen), deriving from a 14 years monitoring programme carried out in two stations of the Po River (the former upstream and the latter downstream the Lambro River input), is treated in terms of oxygen production and consumption. Forecasting models, based on the fugacity concept, are used to predict the distribution of pollutants, both
