“…Similarly, the levels of most trace elements in invertebrates were higher in the viscera than the foot. These results agree with various studies on mollusks (Gundacker 2000;Deng et al 2008;Bao et al 2018). Relatively low concentrations of trace elements in…”

“…Experimental results, however, demonstrated that under Ag exposure some mollusks can accumulate high levels of Ag in their tissues. For instance, in an experiment where sediment was spiked with AgNO 3 to 100 mg/kg up to 75 mg/kg dw, Ag was recorded in the hepatopancreas of the viviparid snail Bellamya aeruginosa (Bao et al 2018). This is much higher than recorded in the invertebrates from our study.…”

This is the first comprehensive report on the accumulation of Cr, Ni, As, and Ag in the fish species Nile tilapia Oreochromis niloticus and Nile perch Lates niloticus from Lake Victoria, complemented with recent data on Cu, Zn, Cd, and Pb. This also is the first report on Cr, Ni, As, and Ag levels in invertebrates: the shrimp Caridina nilotica, gastropod Pila ovata, and bivalve Mutela bourguignati. The study was conducted at five sites in the Kenyan part of Lake Victoria: four sites in Winam Gulf influenced by various anthropogenic pressures, including a site near Kisumu City, and one in the main lake, with lesser direct anthropogenic influence. Apart from Cu and Ag, which were highest in O. niloticus liver, the invertebrates had higher levels of trace elements than fish. Contamination of the gulf with trace elements was best mirrored by the invertebrates, whose mobility is limited; they accumulated Cr, Cd, Ag, and Pb corresponding to the levels in the surface sediment. The accumulation of trace elements in fish species and their bioindicative potential corresponded to their habitats and feeding behaviour. The tissue contents of most trace elements were higher in the inshore-dwelling, omnivorous O. niloticus compared to the pelagic, piscivorous L. niloticus. Cu (465 ± 689 mg/kg dw) and Ag (3.45 ± 1.49 mg/kg dw) in the liver of O. niloticus were up to 10 and 119 times higher than in L. niloticus, respectively. Oreochromis niloticus therefore has bioindicative potential for Cu and Ag contamination. Both the invertebrates and fish showed positive correlations between Cu and Ag concentrations, indicating similar source and/or uptake route. The target hazard quotients (THQ) show that there is no human health risk associated with the consumption of these fish. However, the levels of Zn, Cd, and Pb in P. ovata surpassed maximum food safety limits and are hence potentially unsafe for human consumption.

“…The results varied according to the nature of the Ag-NPs, exposure medium and organism used, highlighting that the interplay of these factors largely determines exposure and bioaccumulation. [32][33][34][35][36][37][38] Benthic ecosystems are essential components of aquatic environments, and benthic organisms may potentially be the biota most affected by ENPs as they can be exposed through both water and sediments. Exposure can potentially happen via ingestion of sediment or food and through direct contact of their body surfaces with both phases (e.g.…”

“…Disturbance of oxidant/antioxidant system has been the main toxic impact induced by NMs in snails. LDH increased the ROS production and subsequently altered the enzymatic and non-enzymatic antioxidant enzyme, such as SOD,CAT, GSH (Ali, 2014b;Ali et al, 2012;Bao et al, 2018). In addition, this reduction can be elucidated to the direct combination of metal with active site of enzyme and its bio-transformation.…”

“…LDH can interact, accumulated in foot and digestive gland of snails, and distributed to the mantle. Both Ag NPs and CuO NPs accumulation in mantle, foot and digestive gland of B. aeruginosa (Bao et al, 2018;Oliver et al, 2014;Croteau et al, 2014;Ma et al, 2017). Also, NMs possessed a highly adhesive property to a cell membrane therefore, it could affect the membrane structures and its macromolecules (Rasel et al 2019).…”

Layered double hydroxide (LDH) nanomaterials have recently become immense research area as it is used widely in industries. So, it's chance of their release into natural environment and risk assessment to non-target aquatic invertebrate increasing. So, the present study aimed to synthesize and confirme the crystalline formation of Co-Cd-Fe LDHs and Co-Cd-Fe /PbI2 (LDH), and then to investigate the toxic impact of the two LDH on the adult freshwater snails (Biomphalaia alexandrina). Results showed that Co-Cd-Fe /PbI2 LDH has more toxic effect to adult Biomphalaria than Co-Cd-Fe LDHs (LC50 was 56.4 mg/l, 72 h of exposure). The effect of LC25 (117.1 mg/l) of Co-Cd-Fe LDHs exposure on the embryo; showed suppression of embryonic development and induced embryo malformation. Also, it showed alterations in the tegmental architectures of the mantle-foot region of B. alexandrina snails as declared in scanning electron micrograph. Also, exposure to this sub lethal concentration caused abnormalities in hemocyte shapes and up-regulated IL-2 level in soft tissue. In addition, it decreased levels of non-enzymatic reduced glutathione (GSH), catalase (CAT), superoxide dismutase (SOD), caspase-3 activity and total protein content in significant manner. While, glutathione S-transferase (GST) activity was not affected by LDH exposure. It caused histopathological damages in both the hermaphrodite and digestive glands. Also, it has a genotoxic effect that was confirmed by alkaline comet assay. The results from the present study indicated that LDH has risk assessment on aquatic B. alexandrina snails and that it can be used as a biological indicator of water pollution with LDH
