Analiza koncentracije hranjivih tvari u površinskim vodama Gaboške Vučice

Gaboška Vučica is a tributary of Vuka River (Municipality of Markušica, Vukovar-Srijem County) and is a collector of wastewater from municipality of Markušica (intensive agriculture). The aim of this study was to collect and analyse concentration of nitrogen and phosphorus compounds (whose concentration in water must comply with the permissible limit value in order to avoid nutrient overload of environment and eutrophication) in surface water of Gaboška Vučica. Samples were taken once a month over the period 2016-2018. Obtained results show that during analysed period concentration of total nitrogen was in the range of 0.43–11.9 mg/L, concentration of nitrites was 0.009–0.036 mg/L, and concentration of nitrates was 0.0113¬–5.42 mg/L, what is higher than in the previously analysed period (2014 and 2015). Concentration of orthophosphates was in the range of 0.005–3.733 mg/L and total phosphorus was in the range of 0.004–0.625 mg/L, what is also higher that in the previously analysed period. The highest concentration of nitrogen and nitrogen compounds were measured in 2016. According to current regulations in Croatia, surface water quality of Gaboška Vučica with regard to chemical parameters can be characterized as moderate. Further continuous monitoring of water quality is necessary in order to improve reliability of water quality categorization, for which purpose specific polluting particulate matter should also be taken into consideration.
