The purpose of the presented paper is to recognize the impact of the Baltic Sea drainage basin, located on Polish territory, on nitrogen and phosphorus riverrine exports to sea. Yearly figures from 1990 to 2011 in Statistical Yearbooks were used. Figures comprising data before were not presented. Load of substance transferred was significantly correlated with water inflow to sea. No trend to increase the load of total and nitrate and total nitrogen was observed, though significant trends to decrease the loads of ammonia nitrogen and phosphate phosphorus were ascertained. Nitrogen and phosphorus loads in wastewater discharged after its purification were significant. The greatest future risk to the Baltic Sea environment is the huge amount of phosphorus application in agriculture in the drainage basin.
