“…Municipal wastewater discharges have a great impact on the water trophic state due to their high content of N and P compounds (Li et al 2012 ; Neverova-Dziopak and Kowalewski 2014 ; Gillmore et al 2016 ). Municipal effluents loads are constantly increasing along with the population growth and the development of urbanisation processes (Lin et al 2020 ).…”

The intensification of the Baltic Sea eutrophication is associated with the increase of anthropogenic nutrients loads, mainly nitrogen and phosphorus introduced into surface waters from a diffuse, point and natural background sources. Despite the observed decreasing trends in nutrient concentrations in some parts of the Baltic Sea, eutrophication-related indicators continue to deteriorate. This accelerates harmful algal blooms and dissolved oxygen deficits resulting in severe ecosystem disturbance. The paper presents trends, insights and effects of the Urban Wastewater Treatment Directive 91/271/EEC implementation in Poland based on the nutrient riverine loads from Polish territory with particular attention given to the development of municipal wastewater treatment plants under the National Wastewater Treatment Programme 2003–2016. Environmental effects of wastewater infrastructure modernisation are investigated by using available data on the changing nutrient concentrations in the coastal water in 3 basins (Gdansk Basin, Bornholm Basin and Eastern Gotland Basin) belonging to the Polish Exclusive Economic Zone within the Baltic Sea. The results show that the decreasing trend regarding phosphorus loads reduction from municipal effluents was achieved while a stable trend with temporary increases was achieved in terms of nitrogen loads. Moreover, the investigation provides information about the potential bioavailability of discharged effluents before and after the Directive implementation by including total and inorganic forms of nitrogen and phosphorus in the analysis.

Anthropogenic eutrophication is one of the consequences of human activities observed from the beginning of urbanization processes and is now a widespread problem around the globe. Mitigation of eutrophication directly corresponds to the achievement of at least three main Sustainable Development Goals. Due to the complexity of eutrophication mechanisms, there are still many issues with managing this process and its consequences, that complicate the achievement of the above-mentioned objectives. So far, there is no universal definition of eutrophication and there is no unified methodological approach to surface water trophic status assessment. In connection with the above, a need arises for the development of scientifically and economically justified methods of reliable trophic state assessment, useful for solving application and engineering tasks. This paper presents a new approach to trophic state assessment based on the innovative universal trophic index (UTI), which can be used for fresh, brackish and saltwater bodies. The proposed UTI index was developed and verified using an extensive database of the Baltic Sea monitoring data for over 100 years. The elaborated method is a reliable tool for the assessment of water trophic status, which also allows for the development of predictive mathematical models as the basis for effective eutrophication management. In addition, the method is simple to use and enables the trophic state assessment at low cost, time and effort. The above-mentioned features make the proposed indicator meet the requirements set for modern ecological indicators and determine the advantage of the proposed methodological approach over other currently used methods.
