Abstract

To achieve a holistic assessment of the water quality dynamics within the principal riverine systems of Yandu District, this study employed a comprehensive analysis of the Water Quality Index (WQI) derived from the monthly monitoring data collected at fifteen designated water quality monitoring stations across the main rivers from 2020 to 2022. The following results were obtained: Firstly, the annual average value of WQI during 2020–2022 was 58.14, and the water quality of Yandu District was considered as generally“moderate”. Secondly, the WQI values in non-flood season were better than those in flood season and the WQI values in the northeast rivers were lower than other rivers. Thirdly, the main factors affecting water quality were NH₃-N, TP, COD_Mn and DO. Therefore, it is necessary to strengthen the monitoring of water quality during the flood season and prioritize the treatment of the northern rivers in the Yandu District. The findings of this research could offer valuable insights for the evaluation, conservation, and management of water quality within analogous riverine systems, thereby contributing to the broader field of aquatic environmental science.

中国盐都区河流水质的时空变化

为全面评估盐都区主要河流水系的水质动态变化，本研究采用了对 2020 年至 2022 年主要河流 15 个指定水质监测站点的月度监测数据所得出的水质指数（WQI）进行综合分析。研究结果如下：首先，2020-2022 年的水质指数年均值为 58.14，盐都区的水质总体为 "中"。其次，非汛期水质指数值优于汛期，东北部河流水质指数值低于其他河流。第三，影响水质的主要因素是 NH3-N、TP、CODMn 和 DO。因此，有必要加强汛期水质监测，优先治理盐都区北部河流。本研究的结果可为类似河流水系的水质评价、保护和管理提供有价值的见解，从而为更广泛的水环境科学领域做出贡献。

期刊介绍： Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation. Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
