“…The aforementioned research conducted also at the neighbouring catchments confirmed that the Słupia River may be considered a representative catchment for the whole Pomeranian region. Therefore, it plays an important role in the estimation of TN loads from the territory of Poland into the Baltic Sea [38][39][40]. The Słupia River has a length of 139 km, and its catchment covers an area of 1623 km 2 .…”

Despite concerted efforts through the European territory, the problems of nitrogen pollution released from agricultural sources have not been resolved yet. Therefore, infringement cases are still open against a few Member States, including Poland, based on fulfilment problems of commitments regarding the Nitrate Directive. As a result of the litigation process, Poland has completely changed its approach to nitrate vulnerable zones. Instead of just selected areas, the measured actions will be implemented throughout the whole Polish territory. Additionally, further restrictions concerning the fertilizer use calendar will be introduced in areas indicated as extremely cold or hot, based on the average temperature distribution (poles of cold, and heat). Such a change will be of key importance to farmers, whose protests are already audible throughout the country, and can be expected to intensify. To assess the impact of the introduced modifications a modelling approach has been adopted. The use of the Macromodel DNS/SWAT allowed for the development of baseline and variant scenarios incorporating details of stipulated changes in the fertilizer use for a pilot catchment (Słupia River). The results clearly indicate that the new restriction will have a substantial effect on the aquatic environment by altering the amount of released total nitrogen.

Due to the ever present problem of excessive eutrophication of both surface waters and their main receiver, i.e. Baltic Sea, it becomes important to determine not only the concentration of nutrients in selected river profiles, but also an attempt to answer the question of which of the elements is a factor limiting the growth of biomass. Biological production in surface area is dependent on a number of factors including the relations between the nitrogen and phosphorus during photosynthesis. The study, whose results were presented in the article, was conducted in 2012–2014 on two littoral river basins, Rega and Słupia, in three cycles throughout the year including both vegetation period, the period after the removal of crops from the fields and the period of early spring, immediately after the thaw snow. On the basis of the results were analyzed variability of daily and seasonal concentrations of biogenic compounds and on the basis determined which of the elements limits the increase in biomass in selected catchments using the dependence that exists between the nitrogen and phosphorus in surface waters called Redfield ratio.

Despite the numerous measures taken to protect its environment for many years, Poland is among the top countries with the largest contributing share in the pollution of the Baltic Sea. It is undoubtedly the case that we are dealing with excesses in the permissible concentrations of total nitrogen (TN) and total phosphorus (TP) on many sections of Polish rivers. However, in order to be able to thoroughly analyze this problem, it is first necessary to increase the frequency of TN and TP monitoring in surface waters. The article presents the first results obtained from the TN and TP monitoring system launched in 2016 at the IMGW-PIB on the calculation profile Szczecin (the Odra River) and Tczew (the Vistula River). The on-line analyzers installed for this purpose make it possible to perform measurements several times a day, allowing for the assessment of diurnal and seasonal variations of TN and TP. Using the results obtained, the daily values of the River Absorption Capacity (RAC) parameter were also calculated. The obtained results showed that, in general, the value of the RAC parameter on the analyzed calculation profiles was positive for both TN and TP throughout the entire period, irrespective of the time of year.
