“…Zinc (Zn) is a nutritional trace element essential for living animals, including aquatic animals [ 14 ], however, excessive Zn concentrations can be toxic [ 15 , 16 ]. Zinc oxide nanoparticles (ZnO-NPs) are inorganic compounds with a wide range of applications in various industries from cosmetics to wastewater treatment [ 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 ].…”

This study was conducted to compare the effects of commercially available (C) and green synthesized (GS) Zinc oxide nanoparticles (ZnO-NPs) on immunological responses of common carp (Cyprinus carpio) skin mucus. GS ZnO-NPs were generated using Thymus pubescent and characterized by UV–vis diffuse reflectance spectroscopy (DRS), Fourier-transform infrared spectroscopy (FTIR), X-ray powder diffraction (XRD), scanning electron microscope (SEM), and energy-dispersive X-ray spectroscopy (EDX). Fish (n = 150) were randomly allocated into five groups in triplicate and received a waterborne concentration of 0% (control), 25%, and 50% of LC50 96 h of commercially available (C1 and C2) and green synthesized ZnO-NPs (GS1 and GS2) for 21 days. Results from XRD displayed ZnO-NPs with 58 nm in size and UV-vis DRS, EDX, and FT-IR analysis showed that some functional groups from plant extract bonded to the surface of NPs. The SEM images showed that ZnO-NPs have conical morphology. Acute toxicity study showed a higher dose of LC5096h for green synthesized ZnO-NPs (78.9 mg.L−1) compared to the commercial source (59.95 mg.L−1). The highest activity of lysozyme and alternative complement activity (ACH50) were found in control and GS1 groups. A significant decrease in alkaline phosphatase activity (ALP) was found in C1 and C2 groups compared to other treatments. Protease activity (P) was significantly decreased in the C2 group compared to the control and GS groups. Total immunoglobulin (total Ig) content was the highest in the control. In addition, total Ig in the GS1 group was higher than GS2. The exposure to ZnO-NPs lowered total protein content in all experimental groups when compared to control. Present findings revealed lower induced immunosuppressive effects by green synthesized ZnO-NPs on key parameters of fish skin mucus.

“…Zn is involved in the nucleic acid synthesis, the immune system, and neurotransmission (MacDonald, 2000). However, at higher concentrations, it can be toxic to fish (Li et al, 2019), and can be a modifier of the carcinogenic response (Bostanci et al, 2016). In humans, acute Zn poisoning may result in nausea, vomiting, diarrhea and fever (Agnew and Slesinger, 2020).…”

Aquatic organisms such as fish are prone to contamination by water pollutants such as heavy metals. This study aims at assessing the levels of heavy metals in the fillet tissues of 75 fish samples comprising Clarias gariepinus (Catfish), Oreochromis niloticus (Tilapia) and Chrysichthys nigroditatus (Bagrid catfish) from five (5) different fishing locations along the Ogun River, Ogun State. The fillet tissues of the fish samples were digested and analysed for Zn, Pb, Fe, Cr and Cd using a Perkin Elmer, AAnalyst – 200 Atomic Absorption Spectrometer. The concentration of Zn in Clarias gariepinus, Oreochromis niloticus and Chrysichthys nigroditatus were 5.37±2.558, 6.58±2.35 and 5.11±1.55 respectively; while the levels of Pb in the species were Clarias gariepinus (1.30±3.099), Oreochromis niloticus (1.01±0.95) and Chrysichthys nigroditatus (0.35±0.59). Concentrations of Fe, Cr and Cd in the species were Clarias gariepinus (8.87±3.547, 0.08±0.098 and 0.09±0.100), Oreochromis niloticus (8.96±2.21, 0.12±0.11 and 0.11±0.11) and Chrysichthys nigroditatus (8.16±3.88, 0.11±0.11 and 0.11±0.11). The data revealed that most of these values were lower than FAO/WHO permissible except Pb and Cr. Some of the fish sampled may pose health hazards to the consumers. There is a need for constant monitoring of pollutants in Ogun River. Keywords: Heavy metals, Clarias gariepinus, Oreochromis niloticus, Chrysichthys nigroditatus, Ogun River

“…Zinc is an essential trace element for aquatic organisms and humans however high concentrations of zinc may cause adverse effects to the organisms [12][13][14][15]. Zinc toxicity to the microalgae Scendesmus obliquus was reported by Li et al [16] with LC50/EC50 value ranged between 0.057-0.217 mg/l. The effect of zinc and manganese on the microalgae Pavlova viridis was studied by Li et al [17,18] and the increase in antioxidant enzyme activity indicated the oxidative stress caused by the metals.…”

Disposal of spent alkaline batteries into the environment is a major concern as the metal leachate enters into aquatic environments. Microalgae are widely used in metal toxicity assay since they are sensitive organisms with a high capacity of bioaccumulation due to their high surface of contact. In this study, zinc and manganese were recovered from spent batteries through acid treatment and the leachate was tested on Chlorella vulgaris for adverse effects. Three acids namely, sulphuric, phosphoric and hydrochloric acid were used as leaching solution to recover the metals from alkaline batteries. Microalgal cells were exposed to the metal leachate and the adverse effects by means of morphological changes were observed. All the tested metal leachates have produced detrimental changes within three minutes of exposure. The results revealed the possible toxicity of metal leachate from battery litters into the environment and its detrimental effect on microalgae.
