“…D. magna exposed to both Ag-NMs and AgNO 3 through different exposure routes (contamination through water only, food only and both water and food) showed a generally lower elimination rate for Ag-NMs compared to AgNO 3 , indicating that Ag from Ag-NM exposure was possibly more difficult to depurate than Ag from AgNO 3 . 65 Additionally, the inert fraction, not excreted from the organism, obtained through kinetics modelling showed that for Ag-NMs this fraction was higher than for ionic Ag.…”

“…2) 73 as was shown in earthworms in which metals were sequestered in stored forms that were not biologically active. 74 Such storage may also be applicable to nanomaterials or the metal ions released from NMs, which was illustrated in studies on the uptake of Ag-NMs in D. magna 65 and in isopods. 9 In such cases, the model may be extended with a stored fraction (SF no dimension).…”

“…Moreover, bioaccumulation was also dependent on route of exposure. Higher bioaccumulation of TiO 2 NPs (<25 nm; Dalai et al 2014) and 80-nm AgNPs (Ribeiro et al 2017) was also observed under combined waterborne and dietary exposure compared with either exposure alone, whereas accumulation of 20-to 75-nm CuO and 16-to 50-nm ZnONPs in goldfish (Carassius auratus) through waterborne exposure alone was found to be 10 times higher than accumulation through the diet . Higher bioaccumulation of TiO 2 NPs (<25 nm; Dalai et al 2014) and 80-nm AgNPs (Ribeiro et al 2017) was also observed under combined waterborne and dietary exposure compared with either exposure alone, whereas accumulation of 20-to 75-nm CuO and 16-to 50-nm ZnONPs in goldfish (Carassius auratus) through waterborne exposure alone was found to be 10 times higher than accumulation through the diet .…”

The experimental determination of bioaccumulation is challenging, and a number of approaches have been developed for its prediction. It is important to assess the applicability of these predictive approaches to nanomaterials (NMs), which have been shown to bioaccumulate. The octanol/water partition coefficient (K ) may not be applicable to some NMs that are not found in either the octanol or water phases but rather are found at the interface. Thus the K values obtained for certain NMs are shown not to correlate well with the experimentally determined bioaccumulation. Implementation of quantitative structure-activity relationships (QSARs) for NMs is also challenging because the bioaccumulation of NMs depends on nano-specific properties such as shape, size, and surface area. Thus there is a need to develop new QSAR models based on these new nanodescriptors; current efforts appear to focus on digital processing of NM images as well as the conversion of surface chemistry parameters into adsorption indices. Water solubility can be used as a screening tool for the exclusion of NMs with short half-lives. Adaptation of fugacity/aquivalence models, which include physicochemical properties, may give some insights into the bioaccumulation potential of NMs, especially with the addition of a biota component. The use of kinetic models, including physiologically based pharmacokinetic models, appears to be the most suitable approach for predicting bioaccumulation of NMs. Furthermore, because bioaccumulation of NMs depends on a number of biotic and abiotic factors, it is important to take these factors into account when one is modeling bioaccumulation and interpreting bioaccumulation results.

“…This is concerning since, in the case of solubility, the toxicity of nanosilver is partly due to the release of silver ions. 15 By comparing columns 1 and 2 of Table 2 we see that the degree of coverage between categories is generally highly variable. However, the degree of criteria fulfilment is, if at least not equivalent, generally higher in column 2.…”

The OECD created the Working Party on Manufactured Nanomaterials (WPMN), which launched the Testing Programme of Manufactured Nanomaterials in 2007 in order to test the applicability of the test guidelines established for chemicals on nanoparticles. After several years of testing, 11 dossiers were made publicly available in 2015. A first analysis of those data reported in these dossiers was performed by Hansen et al. (2017). They conclude that "the information in the dossiers present an incomplete portfolio of nanomaterial ecotoxicological evaluations that are difficult to draw substantive conclusions from and that most of the studies were not designed to investigate the validity of the OECD test guideline." Here, we apply the criteria of the DaNa checklist to evaluate the quality of ecotoxicological data presented in the OECD dossier on silver nanoparticles and compare it with recently published data from other peer-reviewed studies.Our results show that the quality of the nanosilver dossier when considering the original studies from which data are taken is better than that which is presented in the OECD dossier. Additionally, we could not find a difference in the quality of data sources used in the OECD dossiers and data from other peerreviewed studies. When only looking at the dossier, it is rather the quality of the reporting than the actual underlying data sources that is evaluated. Our analysis shows that the quality of those data provided by the OECD testing programme is at least equal to that of non-OECD studies. Overall, these data may be useful in future nanotoxicological evaluation studies.
