摘要

城市发展造成的流域退化增加了地表水对人为污染物的脆弱性。在游泳水域附近排水的城市溪流是造成水质恶化的重要原因。在这项研究中,通过从四个不同的河流站点收集样本,对特尔梅河的微生物质量进行了季节性调查。微生物学分析采用膜过滤标准方法进行。菌落形成单位(CFU)法测定样品中的粪便污染。总大肠菌群、大肠杆菌和产气荚膜梭菌的平均菌落数分别为712 CFU/100 mL、278 CFU/100 mL和64 CFU/100 mL。这种情况说明溪流中有粪便污染。根据《水污染控制条例》中的细菌学参数,特尔梅河的大肠菌群总数为II类水质。研究结果表明,特尔梅河微生物质量污染程度不高,但在污染压力下具有一定的价值。为了不增加污染程度,应防止生活废物/废水、动物废物和河流周围住区和农业区的排水沟直接混合在一起。公众应该意识到必要的预防措施。

Evaluation of spatio-temporal variations in microbial pollution indicators of a river passing through lowlands and urban areas in Northern Türkiye
The degradation of watersheds due to urban development increases the vulnerability of surface waters to pollutants of anthropogenic origin. Urban streams draining near swimming waters can contribute significantly to the deterioration of water quality. In the study, the microbial quality of the Terme River was investigated seasonally by collecting samples from four different stream sites. Microbiological analyzes were performed using standard methods with membrane filtration. The colony-forming unit (CFU) method determined fecal contamination in samples. The mean number of colonies in Terme River water samples was determined as 712 CFU/100 mL, 278 CFU/100 mL, and 64 CFU/100 mL for total coliform, Escherichia coli, and Clostridium perfringens, respectively. This situation indicates that there was fecal contamination in the stream. According to the bacteriological parameters in the Water Pollution Control Regulation, Terme River was found to be of class II water quality in terms of total coliform bacteria count. The Research results determined that the Terme River is not much polluted in terms of microbiological quality but has values under the pressure of pollution. To not increase the pollution level, the direct mixing of domestic wastes/wastewater, animal wastes, and drainage channels from the settlements and agricultural areas around the river should be prevented. The public should be made aware of the necessary precautions.

期刊介绍: The journal (IAR) is an international journal that publishes original research articles, short communications, and review articles in a broad range of areas relevant to all aspects of aquatic sciences (freshwater and marine). The Journal specifically strives to increase the knowledge of most aspects of applied researches in both cultivated and wild aquatic animals in the world. The journal is fully sponsored, which means it is free of charge for authors. The journal operates a single-blind peer review process. The main research areas in aquatic sciences include: -Aquaculture- Ecology- Food science and technology- Molecular biology- Nutrition- Physiology- Water quality- Climate Change
