“…The sub-catchment area of the lake is mainly characterized by clayey and silty types of soil (NBSS and LUP 2001). There are numerous feeder streams and rivers originating from the western hills of the catchment that ow directly into the lake, carrying with them signi cant amounts of anthropogenic wastes, consequently affecting the lake water quality (CGWB 2013; Laishram and Alam 2019; Laishram et al 2022). The lake water nally ows out through the Ungamel channel/Ithai barrage, which serves as the main outlet of the lake located towards the southernmost part of the catchment.…”

“…The deposition of heavy metals in water and sediments can drastically degrade their quality, and due to their toxic, persistent, and bioaccumulative nature, they can undergo a biomagni cation process in the aquatic food chain, consequently causing harm to aquatic life as well as to humans (Rinklebe et al 2016). Similarly, excessive amounts of nutrients can lead to eutrophication of aquatic ecosystems, causing algal blooms, hypoxia, sh mortality, increased sedimentation rates and turbidity of water, along with other undesirable ecohydrological effects (Wisheu et al 1991;Laishram et al 2022). The wetland sediments and plants tend to accumulate the contaminants entering the water body through runoff processes from different natural and anthropogenic sources, in varying degrees (Li et al 2006; Adekola and Eletta 2007; Lu et al 2011;Singh et al 2017).…”

A comprehensive assessment was conducted to evaluate the accumulation of selected heavy metals and nutrients in 10 dominant macrophyte species growing in the Loktak Lake, a Ramsar site, and to assess the potential health risks associated with the consumption of the edible plants. The concentrations of nutrients such as total phosphorus (TP), total nitrogen (TN), potassium (K), calcium (Ca), magnesium (Mg), and heavy metals such as copper (Cu), manganese (Mn), zinc (Zn), and iron (Fe) were measured, and found to be present in the order of plant > sediment > water. The bioaccumulation factors (BAFs) revealed high e ciency of most plants to accumulate heavy metals and nutrients in their tissues from the lake water and sediments, indicating their potential to be used as phytoremediators. Translocation factors (TFs) were also estimated to determine the e ciency of the plants to translocate elements from root to shoot. Colocasia esculenta and Polygonum perfoliatum were found to exhibit the highest BAF and TF values for most of the parameters. Target hazard quotients (THQs) revealed potential health risk associated with one or more heavy metals in the plants, except for Zn whose THQ values were below the level of concern in all the edible plant species. The hazard index (HI) signifying potential non-carcinogenic health risk from the combined effects of all the heavy metals was found to be highest for Polygonum perfoliatum, indicating a potentially higher risk to health if this edible macrophyte is regularly consumed in higher quantities and may pose long-term health effects to the exposed population.

“…The water Quality Index (WQI) is considered to be a mathematical tool to significantly reduce water quality data based on some physicochemical parameters and provide a single classification value that describes the water quality status of water bodies or the degree of pollution. It is primarily proposed by Horton (1965) and later developed then developed by Brown et al (1970), essentially in the majority of the papers on the water quality monitoring of all around the world (Singh et al, 2022;Laishram et al, 2022;El Moustaine et al 2021;Abbasnia et al 2019 ;Madhav et al 2018 ;Bora et Goswami 2017 ;Kaviarasan et al 2016 ;Amiri et al, 2014;Pei-Yue et al, 2010;Ramakrishnaiah et al, 2009;Pradhan, 2001;Horton et al, 1956). The majority of authors are using the Geospatial techniques for the spatial estimation of groundwater parameters.…”

Groundwater in Morocco is restricted because of the semiarid to arid climatic conditions. In this area, the water resources, especially groundwater, are extremely significant. However, it is under threat from organic and inorganic pollution. Furthermore, it is considered the only source of potable water as well as having different usages in Zagora (the southeast of Morocco), making its quantitative and qualitative protection an urgent priority. The present study focused mainly on the anthropogenic impact on the natural resources and groundwater quality around Zagora city by using geospatial techniques and the Water Quality Index (WQI). This paper uses sampling data from 15 wells in the water table of Oasis Fezouata. 15 samples were collected from wells during rainy and dry seasons in two years 2020-2021 and the analysis of the groundwater quality of studied stations. The suitability of the aquifer Fezouata was investigated using drinking and irrigation water quality indices like SSP, SAR, MHs, PI, and KR. The results showed that sulfate and chloride are the dominant anions in the groundwater samples. While the mean abundance of major cations is Na+ > Mg2+ > Ca2+ > K+, the sodium ion is dominant and K+ is the least abundant. The Water Quality Index suggests that 28.55% are good quality water, (23.90%–47.55%) are poor and very poor quality water, respectively, and 40.24% are unsuitable for drinking purposes in 2020. Furthermore, the WQI of the 2021 campaign showed that only 17.48% were considered good quality water and 38.94% (43.58%) were poor or very poor quality water, respectively. However, 33.21% are unsuitable for drinking water. Based on SAR, PI, SSP, KR, and HM values, the majority of groundwater samples can be used for agricultural purposes, notably those of the upstream part of the study area. These results represent an important contribution to the evaluation of groundwater quality and may be influenced mainly by local factors, especially the wastewater treatment stations and mine discharges, which are the primary sources of deteriorating water quality.
