“…The concentration may be another factor that could influence the interaction between heavy metals. For example, the interaction of Zn and Al was synergic effects at lower concentrations but antagonist effects at higher concentrations on the algae Raphidocelis subcapitata (Gebara et al, 2020).…”

“…In aquatic ecosystems, multiple metals coexistence is ubiquity. The aquatic organisms are simultaneously exposed to these compounds, where the metals may have synergistic or antagonistic interactions (Gebara et al, 2020; Rodríguez‐Moro et al, 2020) Therefore, toxicological study of co‐exposure to metals is more meaningful than that of single metal exposure (Zhou et al, 2020). In our laboratory, heavy metal contents in 31 sampling sites of Shaying river in China were detected.…”

Excessive accumulation of Zn2+ or Ni2+ can cause various problems to aquatic animals. In this study, the developmental toxicity induced by individual or combined exposure of Zn2+ and Ni2+ to zebrafish embryos and larvae were evaluated to better understand the interaction between Zn2+ and Ni2+. Both of individual and combined exposure of Zn2+ and Ni2+ could cause obvious developmental toxicity, which mainly occurred after hatching, at a concentration‐dependent manner. The calculated 168‐h LC50 were 2.79 mg/L for Zn2+ and 7.44 mg/L for Ni2+. The interaction of Zn2+ and Ni2+ based on mortality was found to be an antagonism. Various malformations, including tail curving, spinal curvature, pericardial edema, and yolk sac edema, were observed with significant effects on body length and heartbeat rates after exposure of Zn2+ and Ni2+. Meanwhile, some genes related to cardiovascular development and bone formation were mainly down‐regulated by the individual and combined exposure of Zn2+ and Ni2+. The individual exposure was more toxic than combined exposure because the interaction of Zn2+ and Ni2+ was determined to be an antagonism. The down‐regulation of genes related to cardiovascular development and bone formation may contribute to the observed malformation and decreases of body length and heartbeat rates.

“…More specific, Zn induced a significant changes of reactive oxygen species in cells of green alga Raphidocelis subcapitata [34] hence energy cost for the cells. Besides, Zn could replace Mg in chlorophyll molecules, and affect the watersplitting of photosystem II hence impacting photosynthesis and reducing in chlorophyll a content in cells of microalgae [34]. Therefore, in the current study, the exposure to Zn could disorder some processes and caused energy cost in S. bibraianum consequently cell length reduction of this species.…”

Heavy metal contamination is among the globally environmental and ecological concerns. In this study we assessed the development of the two green algae Schroederia setigera and Selenastrum bibraianum under exposures to 5 – 200 µg/L of Ni, Zn, and Cd in the laboratory conditions. Heavy metal removal efficiency of S. setigera was also tested in 537 µg Ni/L, 734 µg Zn/L, and 858 µg Cd/L. We found that the exposures with these heavy metals caused inhibitory on the growth of S. bibraianum. The S. bibraianum cell size in the 200 µg Zn/L treatment was around two times smaller than the control. However, Zn and Cd at the concentration of 200 µg/L did not inhibit the growth of S. setigera over 18 days of exposure. The S. setigera also grew well during 8 days exposed to Ni at the same concentration. Besides, the alga S. setigera could remove 66% of Zn, 18% of Cd and 12% of Ni out of the test medium after 16 days of incubation. The Vietnam Technical Regulation related to metals should be considered for ecological protection. We recommend to test the metal removal by the alga S. setigera at pilot scale prior to apply it in situ

“…This metal is a non-essential element for aquatic life, and high Al concentrations may lead to mutagenic and genotoxic changes and the promotion of bone diseases in vertebrates (Francisco et al, 2018;Rahmani et al, 2018;Chandrapalan and Kwong, 2020). Sources of Al are related to industrial and domestic applications as Al is typically used in antiperspirants, food preservatives and automobile structures (Callewaert et al, 2014;Gebara et al, 2020).…”

This study assessed the concentrations of metals in the Dourados and Brilhante Rivers, investigated the influence of landscape features surrounding these rivers on water quality, and evaluated the risks associated with metal contamination for aquatic biota and human health. Sampling was conducted at eighteen sites distributed along the rivers in June 2016. The concentrations of metals (Cu, Zn, Mn, Fe, Cr, Al and Co) in the water were analyzed by inductively coupled plasma optical emission spectroscopy. All the samples possessed Fe concentrations above the threshold value for aquatic biota (0.3 mg L-1). Moreover, land use and land cover assessment of the study area revealed extensive agriculture activity, particularly in areas surrounding the Dourados River headwaters. Fe bioavailability for both rivers indicated risks for aquatic biota and human health. Overall, the elevated Fe content in these rivers was attributed to anthropogenic activity in the vicinity of these water bodies and the soil characteristics of the area. Considering the importance of river basins, it is necessary to implement public policies for their conservation, especially those related to the cultivation of forests of native species and sustainable agricultural practices, in addition to improving the effluent treatment infrastructure, which is essential to minimize the adverse effects of contamination by chemical elements in water bodies. Keywords: aquatic ecosystems, environmental contaminants, forest fragments.
