Catchment areas of the investigated ponds and reservoirs were classified on the basis of functional zoning of their catchments. It is shown that during the study period the highest nitrate content in all investigated ponds is observed in February, nitrite and ammonium - in December. It is clearly illustrated that high nitrogen pollution is characteristic of ponds and reservoirs, catchment areas of which are the ones with high anthropogenic load. This may be due to runoff from the unorganized rural area located near ponds, as well as to the impact of livestock complexes. The lowest values of the content of nitrogen compounds is observed in ponds and reservoirs, in the territory of catchment areas dominated by arable land and forests, and of low residential load.
