“…The dietary transfer of Ag nanoparticles is known to disrupt the locomotion of springtails (Collembola) [ 21 ]. Additionally, copper (Cu) nanoparticles accumulate in Daphnia magna by dietary transfer and impair their feeding rate [ 61 ]. Therefore, various metal nanoparticles in the environment can produce toxic effects when they are transferred to higher trophic levels.…”

The widespread use of zinc oxide nanoparticles (ZnO-NPs) and their release into the environment have raised concerns about the potential toxicity caused by dietary transfer. However, the toxic effects and the mechanisms of dietary transfer of ZnO-NPs have rarely been investigated. We employed the bacteria-feeding nematode Caenorhabditis elegans as the model organism to investigate the neurotoxicity induced by exposure to ZnO-NPs via trophic transfer. Our results showed that ZnO-NPs accumulated in the intestine of C. elegans and also in Escherichia coli OP50 that they ingested. Additionally, impairment of locomotive behaviors, including decreased body bending and head thrashing frequencies, were observed in C. elegans that were fed E. coli pre-treated with ZnO-NPs, which might have occurred because of damage to the D-type GABAergic motor neurons. However, these toxic effects were not apparent in C. elegans that were fed E. coli pre-treated with zinc chloride (ZnCl2). Therefore, ZnO-NPs particulates, rather than released Zn ions, damage the D-type GABAergic motor neurons and adversely affect the locomotive behaviors of C. elegans via dietary transfer.

“…Additionally, the sediment could act as a sink for CuO-NP and furthermore have negative effects on, for example, the abundance and bioaccumulation of sediment dwelling organisms like Gastrotricha (e.g., Chaetonotus ), Annelida (e.g., Lumbriculus ), and Mollusca (e.g., Lymnea, Physella ). ,,,, In this process, CuO-NP can be transformed more slowly and in a different ration to organic Cu-sulfides and NOM-Cu bound copper compared to added ions (e.g., Cu(NO 3 ) 2 ) resulting in different fate processes. , Avellan et al demonstrated that the persistence and dissolution of NP affects their mobility and accumulation in different compartments. Nanoparticles can also be remobilized and thus become bioavailable and enter the food web, which could subsequently lead to a trophic transfer. ,− The bioavailability of nanoparticulated Cu in fish was twice of that of CuSO 4 . Furthermore, plants could act as a sink for CuO-NP, with a higher deposition/uptake/attachment rate of Cu NP than for Cu(NO 3 ) 2 to plant tissues …”

Transformation, dissolution, and sorption of copper oxide nanoparticles (CuO-NP) play an important role in freshwater ecosystems. We present the first mesocosm experiment on the fate of CuO-NP and the dynamics of the zooplankton community over a period of 12 months. Increasingly low (0.08−0.28 mg Cu L −1 ) and high (0.99−2.99 mg Cu L −1 ) concentrations of CuO-NP and CuSO 4 (0.10− 0.34 mg Cu L −1 ) were tested in a multiple dosing scenario. At the high applied concentration (CuO-NP_H) CuO-NP aggregated and sank onto the sediment layer, where we recovered 63% of Cu applied. For the low concentration (CuO-NP_L) only 41% of applied copper could be recovered in the sediment. In the water column, the percentage of initially applied Cu recovered was on average 3-fold higher for CuO-NP_L than for CuO-NP_H. Zooplankton abundance was substantially compromised in the treatments CuSO 4 (p < 0.001) and CuO-NP_L (p < 0.001). Community analysis indicated that Cladocera were most affected (b k = −0.49), followed by Nematocera (b k = −0.32). The abundance of Cladocera over time and of Dixidae in summer was significantly reduced in the treatment CuO-NP_L (p < 0.001; p < 0.05) compared to the Control. Our results indicate a higher potential for negative impacts on the freshwater community when lower concentrations of CuO-NP (<0.1 mg Cu L −1 ) enter the ecosystem.

“…However, their high detection limits and barely quantitative capacity retrained the applications of these methods in environmental samples. By contrast, analytical methods based on inductively coupled plasma mass spectrometry (ICP-MS) have the competitive advantages of fast and high sensitivity and have been used for quantification and characterization of metal nanoparticles in environmental samples such as lake water, sediments, and algae. − Single particle ICP-MS (SP-ICP-MS) , and size exclusion chromatography coupled with ICP-MS (SEC-ICP-MS) − are capable of characterizing the sizes and determining the concentration of both nanoparticles and ions with high sensitivity and good tolerance to complex matrices, − exhibiting great potential for trace HgNPs analysis in algae.…”
