“…Kaonga et al (2008) studied the ability of Spirogyra aequinoctialis to accumulate Mn from water and concluded it can be used as a biological indicator for long term heavy metal water pollution monitoring. Similarly, Spirogyra subsalsa recorded maximum bioaccumulation of Mn among other algae in another study by Aladdin and Aziz (2020. The next highest concentrations in Spirogyra sp. were of Cu (54.6 -260.2 mg/kg), Cr (27.0 -116.1 mg/ kg) and Pb (13.7 -96.0 mg/kg).…”

Due to the wide occurrence of environmental pollution, heavy metals need to be closely monitored in the aquatic environment because of its ecotoxicological effects on biota. In this regard, biomonitoring as a tool for the assessment of metal pollution in aquatic ecosystem is quite appealing. Therefore, this study was conducted to investigate algae as a potential bio indicator ofheavy metal pollution in an aquatic environment in Fiji. Spirogyra sp. was sampled from a mining impacted water resource and analysed for heavy metals (manganese, copper, chromium, lead and zinc) using atomic absorption spectrometry. The order of metal accumulation in Spirogyra sp. wasfound as Mn > Cu > Cr > Pb > Zn. The results show that Spirogyra sp. is capable of accumulating heavy metals from polluted water and may be used a bioindicator species in environmentalmonitoring. Finally, the elevated heavy metal levels in the VGR aquatic environment could posean ecological risk and appropriate remediation strategies are recommended to minimise adverse impacts to aquatic life.

“…Fortunately, phytoremediation technology, which focuses on the ability of plant roots, stems, and leaves to absorb and accumulate heavy metal elements, has been extensively investigated as a practical alternative to conventional methods [11]. Certain floating, submerged, and emergent plants have been identified as potential heavy metal accumulators [12][13][14][15]. These aquatic plants generally absorb heavy metals via chelation and compartmentalization and, thus, demonstrate tolerance to high heavy metal concentrations [16].…”

“…Several researchers have conducted experiments on the remediating effect of aquatic plants on heavy metal pollution; some review articles have also qualitatively described the heavy metal absorption mechanism of these plants [10][11][12][13][14][15][16]. However, systematic and statistical methods for the comprehensive evaluation of the Hg absorption capacity of aquatic plants are still lacking.…”

The use of phytoremediation technology to remove heavy metal ions from aquatic environments or reduce their toxicity offers the possibility of restoring the ecological environment of polluted water bodies. Based on available literature on heavy metal absorption by aquatic plants, we conducted a meta-analysis to study the absorptive capacities of different plants as well as the factors that influence their Hg-absorption performance. Seventeen plant families, including Araceae, Haloragaceae, Hydrocharitaceae, and Poaceae, have a strong Hg-absorption capacity. The root systems of aquatic plants belonging to these families are primarily responsible for this remediation function, and only a limited proportion of Hg+ that enters a plant via the root system is transferred to other plant organs. Additionally, the diversity of plant life habits (e.g., floating, submerged, and emergent) and the water pH significantly influence the ability of plants to absorb Hg. It is expected that this study will provide a reference for the cultivation of aquatic plants for restoring the ecological environment of Hg-polluted water bodies.

“…Once an algal bloom outbreak occurs, if there have been no measures to reduce the algae in the water outlet area, this will lead to an increase in the amount of chemical used in the water supply to purify it and an increase in the cost of water production [31,32]. Water quality will obviously be severely affected [33,34]. Therefore, water quality restoration near the drinking water outlet area of a eutrophic reservoir is critical [27,30,35].…”
