“…However, in our study, the fine grain fraction (63 microns) was not significant (p<0.05) in determining the concentration of heavy metals in the sediment core of BMR. Although this observed pattern of the sediment grain size relationship with metal is unclear, despite the belief that smaller grain size sediment particles are always associated with heavy metals [67], nevertheless, our finding is supported by a similar study conducted in the Miyun reservoir, China by [70], who reported that grain size fraction in the range of 70 to 95% did not influence the level of heavy metal concentration in the sediment of the lake. There was no correlation found between organic matter and heavy metals, indicating that they were not bound to organic matter and accumulated separately [71].…”

Anthropogenic activities, especially due to agricultural practices, tourism, and other land-use forms, have resulted in serious pollution of Bukit Merah reservoir (BMR), the oldest artificial reservoir in Malaysia since the 1980s. This study assessed the past ecological conditions of the reservoir using 210 Pb, dating techniques, selected metals, and physicochemical analysis of the sediment core to better manage the reservoir. 210 Pb results indicated 34 years of human impact on the reservoir, with arsenic recording the least concentrations in the 1980s and the highest concentrations in 2016 and 2018. The minimum and maximum concentrations of lead and cadmium were found in 1990 and 2009. Whereas Copper and Zinc, concentrations peaked in 2012. The mean EF values of metals in the sediment core were above 1 (EF>1), indicating anthropogenic sources. The I geo values of Arsenic and Cadmium ranged from uncontaminated to strongly contaminated, uncontaminated to moderately contaminated for Lead, Zinc, and Copper. Overall, the dated sediment of BMR revealed that human population growth and increasing economic and agricultural activities coupled with poor land-use forms at the catchment area are the main source of pollution to the reservoir. Therefore, regular monitoring and the enforcement of relevant environmental laws are needed to manage the reservoir.

“…Phosphorus retention in reservoirs increases the reactivity of sediments in these ecosystems contributing to P internal loading in the long term, responsible for algal and cyanobacterial blooms and eutrophication (Harper, 1982;Cooke et al, 1993;Horne & Goldman, 1994;Vo et al, 2014;Qin et al, 2020). The model parameterization indicated that across the spatial scale from the headwater to the dam, the phosphorus trapping on the sediment increases due to the rising of oxidant conditions and neutral pH.…”

“…Dams are mainly constructed for economic purposes, such as water irrigation, water supply, electricity generation and flood control. However, they can also act as a retention basin for pollutants and this has implications for eutrophication and/or for retention of biogenic elements that may cause concerns for water supply, navigation, biodiversity conservation and aesthetic issues (Bartoszek & Koszelnik, 2016;Cunha-Santino et al, 2017;Qin et al, 2020).…”

Potential of the retention capability of a Neotropical reservoir (São Paulo State, Brazil)

Aim Man-made reservoirs lead to several changes in their downstream rivers that depend on the hydraulic characteristics of the reservoirs. However, their multiple uses can also provide facilities that influence the ecosystem services that they provide. This study addressed the potential ability of a Neotropical reservoir to trap chemical species aiming to assess the role of these ecosystems to mitigate pollution. Methods Retention capability modeling was examined for a small subtropical reservoir with high hydraulic retention time (> 100 days). The temporal ranges of 9 physical and chemical water variables over a five-year period were used to calculate the mass balance and to determine the retentive capability (alpha parameter) of the Itupararanga Reservoir (São Paulo State, Brazil). To explain the long-term mass balance of these variables, it was assumed that the reservoir is a completely mixed system with a step input. Results The highest values of parametrized alpha (high retention capability) occurred in wet months (up to 500 mm) for all variables. High reaction rate constants (k) and low hydraulic flushing suggested that sink processes prevail over the export ones, mainly for total phosphorus. The rainfall pattern showed minor importance for trapping elements. Conclusions In the Neotropics, hydraulic characteristics of the ecosystem (e.g., low area:volume ratio) are a tool for pollution management in man-made reservoirs.

“…Flooded soils cause soil hydromorphic processes to develop or intensify, most notably gleyification and the creation of iron and/or iron-manganese concretions. Changes also occur in the transfer, accumulation, and transformation of major nutrients: nitrogen [9,10], phosphorus [11][12][13] and organic matter [5]. All these variables might have an impact on soil bacterial and archaeal communities, but the dearth of published research makes it impossible to evaluate these changes for soils in reservoir flood zones.…”

Studying the soils in the periodical flood zone of three reservoirs is of promising importance for their subsequent return to economic activities. Research on the bacterial and archaeal communities of soils that are periodically or continuously flooded by reservoirs is still insufficient. To evaluate the chemical status of soils and their microbiota, the study was conducted in the Yumaguzino, Nugush, and Slak reservoir sites in the South Ural area (Russian Federation). The bacterial and archaeal communities of periodically flooded and non-flooded soils were investigated after a comparative investigation of chemical, hydrological, and climatic factors. It was discovered that flooded soils had anoxic conditions during the whole of the year, with brief drying intervals of limited length and low levels of effective temperatures. In terms of chemistry, flooded soils are distinguished by increased acidity, a fall in organic matter, and an increase in alkali-hydrolysable nitrogen. Compared to their counterparts in non-flooded soils, bacterial and archaeal communities in flooded soils are significantly different. Generally speaking, the biodiversity of flooded soils rises with the duration and depth of floods. Significant variations at the phylum level are mostly caused by a decline in the relative presence of Thaumarchaeota and an increase in Proteobacteria and Chloroflexi representation. It was discovered that the Euryarchaeota phylum was either absent or had a significantly decreased relative prevalence at the sites of intermittently flooding soils.
