Abstract

River water quality is an important health issue as the water is utilised for drinking, domestic and agricultural use in developing countries. This study aimed to investigate the effect water from a major city has on the water quality of the Jukskei River that daylights in Johannesburg, South Africa. The river water samples were analysed for physio-chemical properties, microbiology, antibiotic resistance of bacterial isolates, genetic markers, and potentially toxic metals. Data analysis revealed increased electrical conductivity, total dissolved solids, and turbidity since 2010. Total Coliform and detected were above the South African water quality guidelines for domestic, recreational, and irrigation purposes. Additionally, sodium, zinc, nickel, lithium, and lead exceeded the guidelines in domestic, recreational, and irrigation water. Pathogenic strains of (aEPEC, EHEC, EIEC, and EAEC) were isolated from the water. Various other potentially pathogenic organisms that have been implicated as causes of gastro-intestinal, and a wide range of other diseases, were also detected and demonstrated multiple levels of resistance to antibiotics tested. The results show that the river water is a potential health threat to downstream users. These results will feed into the environmental management action plan for Water for the Future (NGO group).

摘要

河水水质是一个重要的健康问题,因为发展中国家的人们将河水用于饮用、家庭和农业用途。本研究旨在调查南非约翰内斯堡一条名为朱克斯基(Jukskei)的河流,该河在白天可见,研究城市用水对其水质的影响。研究人员分析了河水样本的理化性质、微生物学、细菌分离物的抗生素耐药性、遗传标记和潜在毒性金属。数据分析显示,自 2010 年以来,河水的电导率、总溶解固体和浊度有所增加。总大肠菌群和耐热大肠菌群的含量超过了南非适用于家庭、娱乐和灌溉用水的水质标准。此外,河水样本中的钠、锌、镍、锂和铅含量也超过了适用于家庭、娱乐和灌溉用水的标准。从水中分离出了(aEPEC、EHEC、EIEC 和 EAEC)等致病性菌株。还检测到了其他各种可能的致病生物,它们被认为是引起胃肠道和其他多种疾病的原因,并且对测试的抗生素表现出多种水平的耐药性。研究结果表明,河水对下游用户构成潜在的健康威胁。这些结果将为未来水资源组织(NGO 团体)的环境管理行动计划提供信息。
