Using Macroelement Content to Characterize Surficial Water Quality of Artificial Reservoirs

Abstract The quality of surface waters in the territory Poland, despite implemented remedial measures, is mostly classified as bad. This article presents results research on composition water macroelements 24 artificial reservoirs located Opole province (southern Poland), searching for reasons behind their pollution. Concentrations anions F − , Cl Br NO 2 3 PO 4 3− and SO 2− cations Na + NH K Mg 2+ Ca were taken into account. An analysis seasonal changes was carried out and, example a dam reservoir (Turawa Big Reservoir), multi-point distribution ion concentrations at also out. It shown that retention flow-through reservoirs, where main source pollution feeding are most vulnerable to second group consists closed industrial agricultural areas, which exposed from rainwater run-off field leachate. In case created marl mining significant effect indicated chemical substrate formation ionic equilibria filling excavations. shows there no hard fast rules regarding variability during growing season, indicating eutrophic show greater concentration.
