“…Zhao et al 25 found that humic acid decreased GO-Al 2 O 3 toxicity to C. pyrenoidosa due to enhanced steric hindrance through a surface coating of GO-Al 2 O 3 heteroaggregates. In contrast, Yu et al 68 demonstrated that Suwannee River NOM increased the relative contribution of dissolved ions released from nCu and nZnO to the toxicity of the binary mixtures at high-effect concentrations of individual ENPs to D. magna . Moreover, the presence of Suwannee River NOM significantly enhanced the accumulation of either nCu or nZnO in D. magna exposed to the ENP mixtures.…”

“…Moreover, the presence of Suwannee River NOM significantly enhanced the accumulation of either nCu or nZnO in D. magna exposed to the ENP mixtures. 68 As depicted in Figure 2 E, the increase in the accumulation of a mixture of ENPs in the presence of NOM may be related to the direct ingestion of metal-NOM complexes and ENP-NOM complexes by water-exposed free-swimming species.…”

The rapid development of nanomaterials (NMs) and the emergence of new multicomponent NMs will inevitably lead to simultaneous exposure of organisms to multiple engineered nanoparticles (ENPs) at varying exposure levels. Understanding the joint impacts of multiple ENPs and predicting the toxicity of mixtures of ENPs are therefore evidently of importance. We reviewed the toxicity of mixtures of ENPs to a variety of different species, covering algae, bacteria, daphnia, fish, fungi, insects, and plants. Most studies used the independent-action (IA)-based model to assess the type of joint effects. Using co-occurrence networks, it was revealed that 53% of the cases with specific joint response showed antagonistic, 25% synergistic, and 22% additive effects. The combination of nCuO and nZnO exhibited the strongest interactions in each type of joint interaction. Compared with other species, plants exposed to multiple ENPs were more likely to experience antagonistic effects. The main factors influencing the joint response type of the mixtures were (1) the chemical composition of individual components in mixtures, (2) the stability of suspensions of mixed ENPs, (3) the type and trophic level of the individual organisms tested, (4) the biological level of organization (population, communities, ecosystems), (5) the exposure concentrations and time, (6) the endpoint of toxicity, and (7) the abiotic field conditions (e.g., pH, ionic strength, natural organic matter). This knowledge is critical in developing efficient strategies for the assessment of the hazards induced by combined exposure to multiple ENPs in complex environments. In addition, this knowledge of the joint effects of multiple ENPs assists in the effective prediction of hybrid NMs.

“…Since CuNPs were not found to be transferred to the predators (mysids) in the present study, the observed changes in feeding rate may be mainly related to the toxic effects of CuNPs on the prey (alga or daphnia). In our previous studies, the median lethal concentration of CuNPs for D. magna was found to be around 0.4 mg Cu/L (Yu et al, 2022). When the studied daphnids were exposed to around 355 μg Cu/L CuNPs, it was observed that some of the alive daphnids tended to swim slowly and became easier to catch during the 24 h exposure period.…”

To date, research on the toxicity and potential environmental impacts of nanomaterials has predominantly focused on relatively simple and single-component materials, whilst more complex nanomaterials are currently entering commercial stages. The current study aimed to assess the long-term and size-dependent (60 and 500 nm) toxicity of a novel core–shell nanostructure consisting of a SiC core and TiO 2 shell (SiC/TiO 2 , 5, 25, and 50 mg L −1 ) to the common model organism Daphnia magna . These novel core–shell nanostructures can be categorized as advanced materials. Experiments were conducted under environmentally realistic feeding rations and in the presence of a range of concentrations of humic acid (0.5, 2, 5, and 10 mg L −1 TOC). The findings show that although effect concentrations of SiC/TiO 2 were several orders of magnitude lower than the current reported environmental concentrations of more abundantly used nanomaterials, humic acid can exacerbate the toxicity of SiC/TiO 2 by reducing aggregation and sedimentation rates. The EC 50 values (mean ± standard error) based on nominal SiC/TiO 2 concentrations for the 60 nm particles were 28.0 ± 11.5 mg L −1 (TOC 0.5 mg L −1 ), 21.1 ± 3.7 mg L −1 (TOC 2 mg L −1 ), 18.3 ± 5.4 mg L −1 (TOC 5 mg L −1 ), and 17.8 ± 2.4 mg L −1 (TOC 10 mg L −1 ). For the 500 nm particles, the EC50 values were 34.9 ± 16.5 mg L −1 (TOC 0.5 mg L −1 ), 24.8 ± 5.6 mg L −1 (TOC 2 mg L −1 ), 28.0 ± 10.0 mg L −1 (TOC 5 mg L −1 ), and 23.2 ± 4.1 mg L −1 (TOC 10 mg L −1 ). We argue that fate-driven phenomena are often neglected in effect assessments, whilst environmental factors such as the presence of humic acid may significantly influence the toxicity of nanomaterials.
