INFLUENCE OF DIFFERENT AREAL POLLUTION SOURCES ON SOME COMPOUNDS CONTENT IN WATER OF DEJGUNY LAKE

The purpose of the work was determination the area pollution influence on mineral compounds content in water of north and west part of Dejguny Lake. There was studied total-P, dissolved PO4 –3 (V), NH4 + ,N O 3 – ,N O 2 – , total-Mg, total-Fe, SO4 –2 and Cl– concentration in water. The most compounds content was in I class of water cleanness. The higher content of nitrate compounds was near the recreation area of Kronowo village and, ammonium and nitrate nitrogen, total phosphorus, ortho dissolved reactive phosphates and magnesium(II), near agricultural area depend on their content in water near the forested area. Moreover, in lake near agricultural area water side was higher content of sulphates(VI) in II class of water cleanness.
