In this study, the water quality of the Baro-Akobo River Basin in Ethiopia was comprehensively assessed. Key parameters including temperature (°C), pH, dissolved oxygen (DO), electrical conductivity, total dissolved solids (TDS), and ion concentrations such as K, Ca, Na, NO , NO , PO , CO , HCO , and NH were measured using standard methods, alongside sampling of phytoplankton, zooplankton, macroinvertebrates, macrophytes, and fish. Phytoplankton and zooplankton were sampled using Hydrobios nets with mesh sizes of 30 μm and 55 μm, respectively, while macroinvertebrates were collected via the kicking method. Results indicated generally alkaline pH levels and elevated turbidity, but acceptable levels of dissolved oxygen and ion concentrations according to WHO and FAO guidelines. Moreover, the study suggests that the wetlands in Gambella and Benishangul-Gumz regions are currently in good condition, providing valuable insights for the conservation and sustainable management of Ethiopia's water resources, ensuring their conservation for both present and future generations. Local authorities can use the study's findings to implement remedial measures to protect water quality and biodiversity in the regions.
在本研究中,对埃塞俄比亚巴罗-阿科博河流域的水质进行了全面评估。使用标准方法测量了包括温度(°C)、pH值、溶解氧(DO)、电导率、总溶解固体(TDS)以及钾、钙、钠、硝酸根、亚硝酸根、磷酸根、碳酸根、碳酸氢根和铵等离子浓度等关键参数,同时对浮游植物、浮游动物、大型无脊椎动物、大型水生植物和鱼类进行了采样。浮游植物和浮游动物分别使用孔径为30微米和55微米的Hydrobios网进行采样,而大型无脊椎动物则通过踢水法收集。结果表明,pH值总体呈碱性,浊度升高,但根据世界卫生组织和联合国粮食及农业组织的指导方针,溶解氧和离子浓度处于可接受水平。此外,该研究表明,甘贝拉和本尚古勒-古姆兹地区的湿地目前状况良好,为埃塞俄比亚水资源的保护和可持续管理提供了有价值的见解,确保为今世后代保护这些资源。地方当局可以利用该研究结果实施补救措施,以保护该地区的水质和生物多样性。
