“…When evaluating the trophic status and level of eutrophication present in an aquatic ecosystem, measuring the amount of dissolved oxygen is considered the most dependable parameter [26].The average value of D.O fluctuated from 2.9 mg/L, 4.6 mg/L, 2.9 mg/L, 5.0 mg/L and 3. Elevated COD levels as depicted in Figure 3 can be linked to the mortality of bacteria and the subsequent decomposition of organic matter, which gives rise to anaerobic conditions [28]. This association suggests that the presence of higher COD levels can be attributed to the death of bacteria and the subsequent breakdown of organic material, ultimately leading to the establishment of anaerobic environments.…”

The experimental investigation was conducted to evaluate the water quality of the Brari Nambal lagoon located in Srinagar city of Kashmir valley. To undertake this study, analysis of physicochemical parameters was carried out at three sampling sites during the winter season of 2022. These results were compared with the data of 2010, 2013, 2016, and 2019 for the same season to determine the changes that have occurred within this time frame. Comparative analysis of data revealed that TP, –PO4 -3, NH4-N, NO- 3N and TDS levels have been increased from 2010 to 2022. Further, the data related to physicochemical parameters was analyzed using Pearson’s correlation method. Water quality of the lagoon was also examined based on the water quality index. Based on current experimental analysis, it is evident that this lagoon is being impacted by increased human activities in its surrounding area, leading to increased urban intensification. This, in turn, affects the overall hydrochemistry of the lagoon. The flexibility to address these issues within the lagoon’s ecosystem can be maintained until external management strategies are implemented to strengthen its natural balance. Implementing specific remedial measures is crucial for the effective management of the lake and the preservation of its natural quality, provided they are executed correctly.

“…Lakes are an important component of water resources and play an irreplaceable role in maintaining ecosystem balance and economic development, particularly in arid and semi-arid areas (Kopprio et al, 2014;Rather and Dar, 2020;Wang et al, 2021). Therefore, the sustainable utilization of lake water resources is the basis of the future social development in many regions, and the safety of lake water quality directly affects the quality of life for residents.…”

Lakes play important roles in sustaining the ecosystem and economic development in Inner Mongolia Autonomous Region of China, but the spatial patterns and driving mechanisms of water quality in lakes so far remain unclear. This study aimed to identify the spatial changes in water quality and the driving factors of seven lakes (Juyanhai Lake, Ulansuhai Lake, Hongjiannao Lake, Daihai Lake, Chagannaoer Lake, Hulun Lake, and Wulannuoer Lake) across the longitudinal axis (from the west to the east) of Inner Mongolia. Large-scale research was conducted using the comprehensive trophic level index (TLI (Σ)), multivariate statistics, and spatial analysis methods. The results showed that most lakes in Inner Mongolia were weakly alkaline. Total dissolved solids and salinity of lake water showed obvious zonation characteristics. Nitrogen and phosphorus were identified as the main pollutants in lakes, with high average concentrations of total nitrogen and total phosphorus being of 4.05 and 0.21 mg/L, respectively. The values of TLI (Σ) ranged from 49.14 to 71.77, indicating varying degrees of lake eutrophication, and phosphorus was the main driver of lake eutrophication. The lakes of Inner Mongolia could be categorized into lakes to the west of Daihai Lake and lakes to the east of Daihai Lake in terms of salinity and TLI (Σ). The salinity levels of lakes to the west of Daihai Lake exceeded those of lakes to the east of Daihai Lake, whereas the opposite trend was observed for lake trophic level. The intensity and mode of anthropogenic activities were the driving factors of the spatial patterns of lake water quality. It is recommended to control the impact of anthropogenic activities on the water quality of lakes in Inner Mongolia to improve lake ecological environment. These findings provide a more thorough understanding of the driving mechanism of the spatial patterns of water quality in lakes of Inner Mongolia, which can be used to develop strategies for lake ecosystem protection and water resources management in this region.
