“…9 As a comparison, recent work has shown α = 0.18 ± 0.07 for dietary TiO 2 NP exposure to zebrafish. 22 α for AgNP trophic transfer to marine medaka was reported to be ∼0.06. 21 The reason that the dietary AgNP and Ag + exposure routes show similar α and BMF k (Table 2) is speculated to be the dynamic fate of AgNPs and Ag + in fish discussed earlier.…”

“…The BMF k values of ∼0.01 for both treatments (Table 2) were ∼2 orders of magnitude smaller than the threshold BMF of unity, consistent with the results of recent studies about AgNPs bioaccumulating in marine medaka (BMF of ∼0.01) and TiO 2 NPs in zebrafish (BMF < 0.024). 21,22,35…”

The toxicokinetic (TK) model‐derived kinetic bioconcentration factor (BCFk) provides a quantitatively comparable index to estimate the bioaccumulation potential of nanoparticles (NPs) that barely reach thermodynamic equilibrium in aquatic organisms, but experimental data are limited for various NPs. In the present study, a machine learning model was applied to offer reliable in silico predictions for the dynamic body burden of diverse NPs to derive corresponding parameters for the TK model. The developed eXtreme Gradient Boosting‐derived TK (XGB‐TK) model was applied to predict BCFk results for a broad range of metallic or carbonaceous NPs, with an appreciable prediction R2 of 0.96. The BCFk values were predicted based on a random combination of selected variable features, revealing that their bioaccumulation potential showed an overall negative correlation with NP density or organism size. By applying importance analysis and partial dependence plots, NP density and organism size were revealed to be the top essential features that impact the bioaccumulation potential. The conjunctively used XGB‐TK model enabled a prior comparison for diverse NPs and straightforward derivation on the dependency of features, which could also guide the bioaccumulation mechanism exploration and experimental condition formulation.

The extensive application of metallic nanoparticles (NPs) in several fields has significantly impacted our daily lives. Nonetheless, uncertainties persist regarding the toxicity and potential risks associated with the vast number of NPs entering the environment and human bodies, so the performance of toxicological studies are highly demanded. While traditional assays focus primarily on the effects, the comprehension of the underlying processes requires innovative analytical approaches that can detect, characterize, and quantify NPs in complex biological matrices. Among the available alternatives to achieve this information, mass spectrometry, and more concretely, inductively coupled plasma mass spectrometry (ICP-MS), has emerged as an appealing option. This work critically reviews the valuable contribution of ICP-MS-based techniques to investigate NP toxicity and their transformations during in vitro and in vivo toxicological assays. Various ICP-MS modalities, such as total elemental analysis, single particle or single-cell modes, and coupling with separation techniques, as well as the potential of laser ablation as a spatially resolved sample introduction approach, are explored and discussed. Moreover, this review addresses limitations, novel trends, and perspectives in the field of nanotoxicology, particularly concerning NP internalization and pathways. These processes encompass cellular uptake and quantification, localization, translocation to other cell compartments, and biological transformations. By leveraging the capabilities of ICP-MS, researchers can gain deeper insights into the behaviour and effects of NPs, which can pave the way for safer and more responsible use of these materials.
