“…The slope of 0.057, which is in good agreement with the transport efficiency of 0.061 reported above, underscored the reliability of our approach. The value of transport efficiency was lower than that of SALD-SP-ICP-MS (0.61) 17 and higher than that obtained by SP-ICP-MS (0.013, 0.0156, and 0.0398) 15, 25, 26 . This is likely due to differences in transport efficiency of the sampling device—i.e., a direct sampling device (i.e., LA and SALD) reduces transport loss in contrast to a solution sampling device with 3%–5% nebulisation efficiency (i.e., nebuliser and spray chamber) 27 .…”

Imaging the size distribution of metal nanoparticles (NPs) in a tissue has important implications in terms of evaluating NP toxicity. Microscopy techniques used to image tissue NPs are limited by complicated sample preparation or poor resolution. In this study, we developed a laser ablation (LA) system coupled to single-particle inductively coupled plasma mass spectrometry (SP-ICP-MS) for quantitative imaging of gold (G)NPs in tissue samples. In this system, GNPs were ablated but did not disintegrate and integrate under optimised operation conditions, which were verified by characterising LA particles by scanning electron microscopy. The feasibility of imaging size distributions in tissue was validated using reference GNPs 60 and 80 nm in size on matrix-matched kidney. A transport efficiency of 6.07% was obtained by LA-SP-ICP-MS under optimal conditions. We used this system to image 80-nm GNPs in mouse liver and the size distribution thus obtained was in accordance with that determined by nebuliser SP-ICP-MS. The images revealed that 80-nm GNPs mainly accumulate in the liver and did not obviously aggregate. Our results demonstrate that LA-SP-ICP-MS is an effective tool for evaluating the size distribution of metal NPs in tissue.

“…In the years since 2008, the situation has been improved by the development of new methods such as NP tracking analysis, hyphenated methods such as field flow fractionation with inductively coupled plasma-mass spectrometry (FFF-ICP-MS; Meisterjahn et al 2016), and especially single-particle (SP)-ICP-MS (Reed et al 2012;Bi et al 2014;Yang et al 2016;Tharaud et al 2017). Nanoparticle tracking analysis may give more accurate data compared to dynamic light scattering (Domingos et al 2009), and SP-ICP-MS allows the single and ensemble analysis of particle number and concentration on an ion-specific basis (Merrifield et al 2017a).…”

The present review covers developments in studies of nanomaterials (NMs) in the environment since our much cited review in 2008. We discuss novel insights into fate and behavior, metrology, transformations, bioavailability, toxicity mechanisms, and environmental impacts, with a focus on terrestrial and aquatic systems. Overall, the findings were that: 1) despite substantial developments, critical gaps remain, in large part due to the lack of analytical, modeling, and field capabilities, and also due to the breadth and complexity of the area; 2) a key knowledge gap is the lack of data on environmental concentrations and dosimetry generally; 3) substantial evidence shows that there are nanospecific effects (different from the effects of both ions and larger particles) on the environment in terms of fate, bioavailability, and toxicity, but this is not consistent for all NMs, species, and relevant processes; 4) a paradigm is emerging that NMs are less toxic than equivalent dissolved materials but more toxic than the corresponding bulk materials; and 5) translation of incompletely understood science into regulation and policy continues to be challenging. There is a developing consensus that NMs may pose a relatively low environmental risk, but because of uncertainty and lack of data in many areas, definitive conclusions cannot be drawn. In addition, this emerging consensus will likely change rapidly with qualitative changes in the technology and increased future discharges.

“…However, in SP-ICP-MS mode with the interfering in particulate form, the induced Zr interference would be similar to the signal of a Ag particle and could not simply subtracted since randomly distributed. The detection of Np 107 Ag in significant concentrations in natural waters compared to wastewater effluents may raise questions about their occurrence and interferences from natural suspended particles [7]. In this study, we thus propose to determine the interference of particulate and colloidal Zr on the detection of NP-Ag in natural waters by SP-ICP-MS using both natural 107 and 109 Ag isotopes.…”

“…The analysis of Ag by ICP-MS presents isobaric interferences, both with the Ag isotopes 107 and 109, due to the presence of natural zirconium (Zr) in the sample. The isotope 107 is frequently used for the detection of Np Ag in various environmental samples [7,8]. For the isotope 107, the interfering elements are 91 Zr 16 O and 90 Zr 16 O 1 H, while the elements 92 Zr 16 O 1 H for the isotope 109 [9,10].…”

Background: The analysis of silver nanoparticle (NP-Ag) by the single particle technique with argon plasma-coupled mass spectrometry (SP-ICP-MS) is an increasingly used analytical approach. The sensitive technique, distinguishing particle size distribution, allows working at concentrations similar to those found in environmental samples. The two natural Ag isotopes 107 and 109, with abundances of 52 and 48% respectively, have similar sensitivity in ICP-MS detection. However, it is common to encounter isobaric interferences in mass spectrometry, and the element silver is not an exception, as much with the 107 isotope as 109. For both isotopes, zirconium oxides present isobaric interferences, either 91Zr16O, 90Zr16O1H for the isotope 107 and the 92Zr16O1H for the 109. Results: For surface water analysis by ICP-MS in regular technique, these interferences do not generally impact the analysis of total Ag concentrations (mainly dissolved) as they can be then simply subtracted like background signal. On the other hand, detection of NPAg was impacted by the interfering colloidal Zr. The analysis of Zr by the SP-ICP-MS technique of surface waters showed the presence of colloidal Zr, a random signal that cannot be simply subtracted from NP Ag signal. Our results show that, Zr colloids are effectively interfering with the NP-Ag assays by SP-ICP-MS technique where interferences translated into a false positive. Conclusion: The analytical issue related isobaric interferences from the naturally occurring colloidal Zr was attenuated (up to 250% in this assay) by the use of the 109 isotope in the Ag detection, limiting false positive detections and improving the reliability of NP-Ag measurements in natural waters. Therefore , more specific detection of NP Ag in surface waters that naturally contain Zr colloids can be accomplished.
