Description	Summarizing the change in eutrophication indicators in Lithuania, it is obvious that the state of the environment is not good according to most eutrophication indicators. The multi-annual trends in these indicators are quite contradictory and seem to reflect the climatic fluctuations that charact...	The runoff of the Nemunas River makes up over 85% of all nitrogen of river origin entering the Lithuanian Baltic Sea area. According to long-term research data, on average, over 40.0 thousand people enter the Baltic Sea on the Nemunas per year. T total nitrogen. A comparison of the inflow of the ...	The results of the monitoring of the last decade show that the average concentrations of total nitrogen in the part of the Baltic Sea belonging to Lithuania in winter are decreasing, although the trends of mineral nitrogen concentrations are not clear. The average concentrations of mineral nitrog...	The runoff of the Nemunas River makes up over 90% of the total phosphorus of river origin entering the Lithuanian Baltic Sea area. According to the data of multi-year surveys, on average, about 2.0 thousand. T of total phosphorus. A comparison of the inflow of the Nemunas with the instantaneous a...	The concentration of total phosphorus compounds did not change much and in various parts of the Lithuanian Sea area of the Baltic Sea during the study period it ranged from 0.030 to 0.034 mg P / l in summer and from 0.039 to 0.044 mg P / l in winter. The average concentration of phosphate phospho...	Unknown_NotAssessed		The maximum amounts of chlorophyll a in the water surface layers of the Baltic Sea region of Lithuania in the last decades averaged up to 21.8 µg / L in the area of influence of the Curonian Lagoon waters.	Over the last decade, the maximum depth of distribution of the branched whale habitat ranged from 6 to 16 m on the coast, i. in some parts of the coast, water quality varied from poor to moderate or good.
