“…Fe, Cu, Mn, Zn, Ni, Pb and Cd) concentrations in wetland water ranged from (0.32, 0.04, 0.34, 0.27, 0.016, 0.032 and 0.0029 mg/L) to (0.69, 0.13, 0.57, 0.43, 0.038, 0.066 and 0.0051 mg/L) with lower concentrations in summer and higher concentrations in winter (Table 1-2). In summer lower heavy metal concentration may be attributed to macrophytes absorbing heavy metals during their peak growth stage (Showqi et al 2018). In the similar manner, the highest concentrations of heavy metals in the winter may be due to the death and decay of the macrophytes, which releases their locked-up elements in the growing media.…”

“…Heavy metals are common pollutants and almost all the fresh water bodies are contaminated by metal pollution (Sudarshan et al 2020). Metals like Fe, Cu, Mn, Zn and Ni are essential for plants and animals (Showqi et al 2018), while Cd and Pb are non essential (Norouzi et al 2012). All heavy metals, whether essential or non essential have the ability to accumulate and biomagnify along the food chain and threaten human and aquatic life (Miretzky et al 2004;Walker et al 2006; Feng et al 2017).…”

The present study analyzed the levels of Fe, Cu, Mn, Zn, Ni, Pb and Cd in water, sediment and macrophytes (viz Potamogeton crispus and Trapa natans) of Shallabugh wetland from December 2017 to November 2018 at three selected sites. The values of heavy metals in water and sediment reflected higher concentrations in winter at site II and lower in summer at site I. However, macrophytes accumulated high concentrations of heavy metals during summer at site II and lower values during autumn at site I. In water, all heavy metals were found within EPA limits except Fe and Mn and sediments were classified as non-polluted. In macrophytes Cu, Zn and Ni were found below WHO limits, whereas, Pb and Cd were above the limits. The contamination factor for all heavy metals was < 1 except for Cd which show moderate degree of contamination (CF < 3). The pollution load index values were < 1 and geoaccumulation index values were < 0 indicates unpolluted sediment. The bioconcentration factor for both the macrophytes was > 1, hence both the species can be regarded as potential phytoremediators. The correlation analysis indicates a significant positive dependency between water and sediment whereas negative correlation was observed between heavy metals in water and sediment with macrophytes (p < 0.01). The study suggests continuous assessment of water, sediment and macrophytes in order to serve as a useful link for indicating pollution levels and to minimize the potential health hazards.

“…The conical flask was heated until the solution was fully evaporated, then the flask was cooled at room temperature. The powdery deposition was noticed on complete evaporation, 100 ml of triple distilled water was introduced in the powdery deposit to each conical flask to completely dissolve it before the AAS analysis (Showqi et al, 2018). The fish organ samples such as liver, kidney, gills,and muscles were washed with 0.9 % saline water.…”

Abstract: The present study revealed the chromium toxicity and its health measures in L. rohita from the Yamuna river at Mathura- Agra region. Samples were taken in triplicate from both sites i.e. Vrindavan (Bihar ghat) and Agra (Renuka Ghat). The study was carried out on Four different organs (i.e. gills, muscles, liver, and kidney) of the fish sample. The sampling was done from Oct 2018 to January 2020. Chromium concentration in different organs of the fish was analyzed by Atomic absorption spectrophotometer(AAS). The average Cr concentration in gills was highest (9.64 mg/l) at the Mathura site followed byAgra sites (7.78 mg/l) for the month of April 2019. The concentration of Cr was highest in samples taken in the month of April 2019 and it was lowest in October 2018. The significantly high Cr concentration values were observed in the Mathura region than the Agra region for both seasons. In all samples, Cr concentration was above the standards stated by WHO except in the Kidney. In the present study, the bioaccumulation factor showed the chromium concentration in the tissues followed the order of gill > liver > muscle > kidney. HPI, MQI, and Pearson’s correlation coefficient analysis were also done in which HPI was observed very high and there was a positive correlation between all the samples. Keywords: Chromium, BCF, HPI, MQI, AAS, Fish Organs

“…The standard values for common heavy metal constituents in lake water are listed in the table 3. This table is prepared with the report released by WHO and BIS in past [14][15], [19][20][21][22]. The values for some parameters may vary in accordance to the intended use of the water such as for drinking and irrigation purposes, aquatic life and as per the level of the water:…”

With this article, impact of effluent mixed water with the quality of the Mansagar Lake has been established by evaluating the physico-chemical parameters and the heavy-metal contents experimentally. The process of calculating water quality and the metal pollution quality indices is also explained in brief with respect to selected sample locations and varied environmental conditions (Pre- and Post-Monsoon season). Distribution trends of Pearson‘s correlation factor have also been discussed to establish their relation among the physico-chemical parameters and the heavy-metal contents for varied environmental conditions. In the end, detailed discussion on observations made during this study and useful recommendations are also elaborated in details. With this article, we intend to present a document for better understanding of the water quality of this lake in view of futuristic management strategies to be adopted to maintain it heritage values.
