Inputs of nutrients (nitrogen and phosphorus) to the subbasins (2015)

A significant reduction of nutrients input has been achieved for the whole Baltic Sea. This assessment shows that the normalized input of nitrogen was reduced by 12% and phosphorus by 25% between the reference period (1997-2003) and 2015 (Results figure 1). The maximum allowable input (MAI) of nitrogen in this period was fulfilled in the Kattegat, Danish Straits, Bothnian Bay and Bothnian Sea (Key message figures 1 and Results tables 1a and 1b). Nitrogen input into the Gulf of Riga is below MAI but cannot be considered as fulfilled due to statistical uncertainty. MAI for phosphorus input is fulfilled in the Kattegat, Danish Straits and Bothnian Sea. The inputs to the Gulf of Finland and Bothnian Bay are below MAI but cannot be considered as fulfilled due to statistical uncertainty
