Abstract
Površinske vode upotrebljavaju se za piće, industriju, navodnjavanje poljoprivrednih površina te za uzgoj slatkovodnih riba. Kakvoća vode je bitna kako za čovjeka, tako i za živi svijet u vodi. Onečišćenjem voda spojevima s ugljikom, dušikom i fosforom dolazi do eutrofikacije voda. U ovom radu određivali su se fizikalno-kemijski pokazatelji kakvoće tekućica i stajaćica u Hrvatskoj mjerenjem pH-vrijednosti, električne provodnosti, sadržaja iona, hranjivih tvari (dušikovi spojevi, ukupni fosfor i... More fosfati), režima kisika (kemijska i biokemijska potrošnja kisika) i ukupnog organskog ugljika. Iz dobivenih rezultata je vidljivo kako površinskim vodama panonske regije prijeti onečišćenje nitratima, amonijem i organskim tvarima čiji je porijeklo najvjerojatnije iz neobrađenih otpadnih voda. Također, nekim površinskim vodama panonske regije prijeti eutrofikacija jer su u dva uzorka prisutne koncentracije fosfora iznad 0,35 mg P/L, a u dva uzorka su koncentracije nitrata veće od 11,1 mg/L. Analize su, također, pokazale kako jedan od četiri testirana ribnjaka nije pogodan za uzgoj riba jer je koncentracija amonija bila veća od 0,2 mg/L, a biokemijska potrošnja kisika veća od 5 mg/L.

Abstract (english)
Surface waters are used for drinking, industry, irrigation of agricultural land, and for fish farming. Water quality is important for both humans and the other living life in water. Water contamination with carbon, nitrogen and phosphorus compounds leads to eutrophication. In this paper, physico-chemical quality indicators of surface water in Croatia were determined by measuring pH, electrical conductivity, ion content, nutrients (nitrogen compounds, total phosphorus, and phosphates), oxygen... More regime (chemical and biochemical oxygen consumption) and total organic carbon. The results indicate that surface waters of Pannonian region are threatened by pollution with nitrates, ammonium and organic substances, the origin of which is most likely untreated wastewater. Also, some surface waters of Pannonian region are threatened by eutrophication because in two samples phosphorus concentrations were above 0.35 mg P/L and in two samples nitrate concentrations were higher than 11.1 mg/L. Analyzes have also shown that one out of four ponds was not suitable for fish farming because the ammonium concentration was higher than 0.2 mg/L and the biochemical oxygen consumption was higher than 5 mg/L.
