“…GSH, a major low-molecular-weight antioxidant, can directly scavenge singlet oxygen and hydroxyl radicals to intact cells under oxidative stress (Halliwell 1993). A previous study has shown that GSH content was reduced in the early life stages of zebrafish (Danio rerio) exposed to 125 μg Cu/L, and indicated that the decreasing in GSH levels is probably due to its increased use as a cofactor of antioxidant enzymes and, consequently, the re-establishment of cellular ion and redox homeostasis under severe stress (Santos et al 2020). Our study showed that Cu decreased GSH contents in the livers of the 100, 200, and 400 μg Cu/L groups.…”

“…Pollution of Cu 2+ is caused by manning activities, electroplating, smelting, and the utilization of copper-based agrichemicals and manufacturing of brass. Copper is the most toxic metal to animals, and long-term inhalation of Cu-containing sprays has been linked to an increased risk of lung cancer in those who have been exposed 5 . At low levels, copper can play a significant role in human and animal metabolism.…”

The present research involves removing copper and nickel ions from synthesized wastewater by using a simple, cheap, cost-effective, and sustainable activated green waste tea residue (AGWTR) adsorption coupled with electrocoagulation (ADS/EC) process in the presence of iron electrodes. By considering previous studies, their adsorbents used for treating their wastewaters firstly activate them by applying either chemicals or activating agents. However, our adsorbent was prepared without applying neither chemicals nor any activating agents. The operating parameters such as pH, hydraulic retention time, adsorbent dose, initial concentration, current density, and operating cost for both metals were optimized. In ADS/EC, the removal efficiency was obtained as 100% for copper and 99.99% for nickel ions. After the ADS/EC process, Fourier transform infrared (FT-IR) spectroscopy, Scanning Electron Microscopy (SEM) and Energy-dispersive X-ray spectroscopy (EDS) analysis were used to characterize the adsorbent green waste tea residue. The adsorption isotherm and kinetic model results showed that the Langmuir and the pseudo-second-order were well-fitted to the experimental adsorption data better than the Freundlich and pseudo-first-order models for both Cu2+ and Ni2+ with their maximum adsorption capacity of 15.6 and 15.9 mg g−1, respectively. The above results give an option to recycle the metal-based industrial effluents, tea industry-based wastes, enabling a waste-to-green technique for adsorbing and removing the heavy metals and other pollutants in water.

“…The toxic potency of Cr(VI) and MPs to organisms can be synergistic or antagonistic under different abiotic factors, such as concentration, exposure period, pH, salinity, alkalinity, hardness, and temperature; and biotic factors, including developmental stage, organs, and species [ 10 , 29 ]. In zebrafish, both synergistic [ 30 ] and antagonistic effects [ 31 ] have been suggested to result from the combined exposure to MPs and copper. In zebrafish embryos, combined exposure to MPs and cadmium caused synergistic detrimental effects by reducing heart rate and inducing growth retardation.…”

The prevalence of hexavalent chromium [Cr(VI)] and microplastics (MPs) is ubiquitous and is considered a threat to aquatic biota. MPs can act as a vector for waterborne metals; however, the combined effects of Cr(VI) and MPs on aquatic organisms are largely unknown. In this study, aquatic model animals, such as rotifers (Brachionus calyciflorus and B. plicatilis), water fleas (Daphnia magna), amphipods (Hyalella azteca), polychaetes (Perinereis aibuhitensis), and zebrafish (Danio rerio) were exposed to environmental concentrations (1, 10, and 100 particles L−1) of 1 μm polystyrene MPs alone, Cr(VI) alone, or Cr(VI) combined with MPs. Following exposure, the potential effects were measured by analyzing basic life endpoints (e.g., survival rate and growth). A significant response to MPs alone was not observed in all animals. However, MPs combined with Cr(VI) concentration-dependently increased Cr(VI) toxicity in two rotifer species. The survival rate of water fleas was significantly reduced upon exposure to Cr(VI) + MPs (100 particles L−1) compared with exposure to Cr(VI) alone, and significantly decreased the number of offspring. Although there was no significant effect on the body length of the amphipod, concentration-dependent decreases in their survival rates were observed. In contrast, no significant change was found in the survival rate of polychaetes; however, their burrowing ability was inhibited by Cr(VI) + MPs (100 particles L−1). Further, larval mortality was increased in response to Cr(VI) + MPs (100 particles L−1) in zebrafish. Taken together, the findings suggest that MPs can exacerbate Cr(VI) toxicity, even at environmental levels.
