Wstępna ocena poziomu stężenia mineralnych związków azotu i fosforu w wodach powierzchniowych zlewni jeziora Świdwie. Folia Pomer. Univ. Technol.

In investigated water courses the concentration of nitrate nitrogen(V) classified water to I purity class and concentration of ammonium nitrogen classified most of these water-courses to II purity class. Whereas the concentration of the phosphate phosphorus(V) on the most of examined water- -courses exceeded II class limits for surface waters (especially on water courses running by built-up area). Positive influence of the Żurawie reservoir on the quality of waters flowing in to the Świdwie lake was noted. On the base of obtained results we concluded that Struga Żurawia and canal Bolkowo-Łęgi leading large amounts of phosphate phosphorus to Świdwie lake. It may cause to increased process of its eutrophication. However we did not found large amounts of investigated biogenic compounds in river Gunica which flows to Świdwie lake. On Świdwie lake outflow lower concentration of phosphorus(V) what is the evidence of phosphates cumulation in the lake.plUznanie autorstwa-Użycie niekomercyjne 3.0 Polskaazotfosforjakość wódjezioro Świdwiewody powierzchniowebiogenic compoundslake Swidwienitrogenphosphorussurface waterwater qualityDyscyplina::Nauki rolniczeWstępna ocena poziomu stężenia mineralnych związków azotu i fosforu w wodach powierzchniowych zlewni jeziora ŚwidwiePreliminary Estimation of Mineral Nitrogen and Phosphorous Concentration in Surface Waters in the Świdwie Lake CatchmentArticle2300-5378
