The irresponsible and uncontrolled use of water bodies for long period of time leads to pollution and water quality degradation, particularly in sensitive protected terrestrial and aquatic areas as lakes and wetlands situated in the vicinity of human habitations. Vulnerable ecosystems, the Lake Zobnatica, Serbia and the Wetlands of Tompojevci, Croatia, are characterized as protected natural areas and are surrounded by agricultural land and developed anthropogenic activities. In the samples of surface, ground water and agricultural runoff the key physicochemical parameters were determined. The results of analysed water characterized the Lake water quality class as IV-V. The measured parameters for the Lake show the high values of nutrients, particularly in ground water and agricultural runoff, pH value higher than 8.5 and lower values of dissolved oxygen (DO) than 5 mg/L in the most of the examined water samples. According to the results and maximal allowable values Wetlands belong to the class V water quality, with high trophic state and poor eco-status according to Croatian and Serbian national Laws and By-Laws. The pH value higher than 8.5 of ground water in Wetlands of Tompojevci signifies alkaline groundwater. The maximum concentrations of orthophosphates in ground water and agricultural runoff (10.875 and 10.886 mg/L, respectively) imply the high level of agricultural pollution. Research study of water samples has been performed from 2017 to 2019 within the Interreg IPA CBC Croatia-Serbia Project AF_HR-RS135_SeNs_Wetlands. This type of parallel and comparative research in Serbia and Croatia was conducted for the first time.
长期以来,水体的不负责任和不受控制的利用导致了污染和水质恶化,特别是在湖泊和湿地等靠近人类住区的敏感保护陆地和水域。塞尔维亚的佐布纳蒂察湖和克罗地亚的汤波杰维奇湿地等脆弱生态系统被划为自然保护区,周围是农田和发达的人为活动。对地表水、地下水和农业径流的样本进行了关键物理化学参数的测定。分析水样的结果将湖水水质类别定为 IV-V 类。测量参数显示,湖水中的营养物质含量较高,特别是在地下水和农业径流中,pH 值高于 8.5,大部分水样中的溶解氧(DO)值低于 5mg/L。根据结果和最大允许值,湿地属于 V 类水质,具有高营养状态和较差的生态状态,这符合克罗地亚和塞尔维亚国家法律和地方法规。汤波杰维奇湿地地下水的 pH 值高于 8.5,表明地下水呈碱性。地下水和农业径流中 orthophosphates 的最大浓度(分别为 10.875 和 10.886mg/L)意味着农业污染程度较高。在 2017 年至 2019 年期间,在跨区域合作倡议(IPA)克罗地亚-塞尔维亚合作方案 AF_HR-RS135_SeNs_Wetlands 内对水样进行了研究。这种在塞尔维亚和克罗地亚的平行和比较研究是首次进行的。
