Sažetak
Svržnica is a small lowland drainage canal that flows into the river Biđ. To raise public interest in adequately managing water resources, the monitoring of biological, physical, and chemical elements of water quality was carried out, from spring to winter, at four sites of the canal: S1 - a pre- discharged site characterized by the high representation of macrophytes ; S2 - immediately after the discharge of municipal wastewaters characterized by the complete absence of macrophytes ; S3 - the oak forest site with ruderal plants and poorly represented macrophytes ; S4 - at the mouth of the canal into the Biđ river, with large macrophyte cover. The water quality was mainly moderate based on physical and chemical elements, with high phosphorus and organic nitrogen load throughout the year of sampling, except on the S1 site. The highest representation of algae was established in late spring at all locations. At the same time, their presence was negligible in other seasons. Indicators of faecal contamination were determined in water samples at S2 and S3, and the microbiological load was more significant in the winter. Screening phytotoxicity tests with Lemna minor were conducted using undiluted water samples. Chlorosis, colony structure breakup, and buoyancy loss were noted in all water samples, and the most significant phytotoxicity effect in waters from the S1 site was due to deficient nutrients.
