20.500.12556/RUL-170586 Analiza osnovnih fizikalnih in kemijskih značilnosti izbranih vodotokov v porečju Temenice Analysis of Basic Physical and Chemical Characteristics of Selected Watercourses in the Temenica River Basin V magistrskem delu smo preučevali fizikalno-kemijske značilnosti vodotokov v porečju reke Temenice, s poudarkom na oceni kakovosti vode glede na sezonske in prostorske spremembe. Vzorčenje smo izvajali mesečno med februarjem 2022 in februarjem 2023 na 13 lokacijah vzdolž porečja. Meritve so vključevale parametre, kot so pH, temperatura, nasičenost in koncentracija kisika, električna prevodnost ter koncentracije amonijevih, nitratnih, nitritnih in fosfatnih ionov. Rezultate smo primerjali z uradnim monitoringom Agencije RS za okolje (ARSO) za obdobje 2008–2023. Analiza je pokazala, da je kakovost vode najslabša na odseku med naseljem Trebnje in ponorom pri naselju Grm, kjer se nahajajo številni točkovni viri onesnaževanja, vključno s komunalno čistilno napravo in industrijsko dejavnostjo. Nasprotno so izvirne točke, kot sta Zijalo in Prečna, kazale na izboljšano kakovost vode, kar kaže na vpliv podzemnih vod iz manj obremenjenega zaledja. Rezultati potrjujejo pomemben vpliv človekovih dejavnosti, predvsem urbanizacije, industrije in kmetijstva, na kakovost površinskih voda. Na podlagi ugotovitev predlagamo razširitev monitoringa in dodatne ukrepe za zmanjševanje onesnaževanja iz točkovnih in razpršenih virov. In this master's thesis, we analyzed the basic physical and chemical characteristics of selected watercourses in the Temenica River basin that affect water quality. Measurements were conducted from February 2022 to February 2023 at 13 sampling locations, with samples taken monthly (12 times in total). Based on the results, we analyzed the concentrations of ammonium, nitrate, nitrite, and phosphate ions, as well as oxygen concentration, electrical conductivity, pH value, and water temperature. We compared our results with official monitoring data collected at three locations in the basin between 2008 and 2023. The results show that the most polluted section lies between the settlement of Trebnje and the sinkhole near the village of Grm, where pollutant concentrations were the highest. This area hosts numerous point sources of pollution, particularly the Trebnje municipal wastewater treatment plant and industrial activity. Spring sites such as Zijalo and Prečna showed improved water quality, confirming the mixing of water from less populated karst hinterlands. Key findings of the study confirm the impact of anthropogenic factors—especially households, industry, and agriculture—on water quality in the Temenica basin. Based on the analysis, we recommend additional monitoring and the implementation of measures to improve control over wastewater discharges and reduce agricultural surface runoff. kakovost voda Temenica Prečna dolenjski kras fizikalno-kemijski parametri onesnaževanje voda water quality Temenica Prečna Dolenjska Karst physico-chemical parameters water pollution true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2025-07-10 07:46:00 2025-07-10 07:46:09 2025-07-13 03:44:24 0000-00-00 00:00:00 2025 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 582690 49305.pdf 49305.pdf 1 9DEE9ACBA60037E8BE2EF280D15A0E74 309c70ebac837b4b470d57d1dec49ceca4632548391df5ca382ce852d539c669 43941e66-5d4f-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=212616 Filozofska fakulteta 0 0 0
