TL;DR: This paper presents a practical guide on how to count and size nanoparticles using spICPMS, and an alternative protocol is provided for determining particle size that broadens the applicability of the technique to all types of inorganic nanoparticles.

TL;DR: This study compares sizing of four silver nanoparticle dispersions by spICPMS to four established sizing techniques: dynamic light scattering, differential centrifugal sedimentation, nanoparticle tracking analysis, and TEM, and shows that sp ICPMS is able to size silver nanoparticles, across different sizes and particle number concentrations, with accuracy similar to the other commercially available techniques.

TL;DR: Results indicate that dissolved silver was responsible for the toxicity and highlight the need to account for matrix components such as chloride and organic matter in natural waters that influence AgNP fate and mitigate toxicity.

TL;DR: Results demonstrate that DGT is a useful tool for assessing metal bioavailability in sediments and can provide useful predictions of metal bioavailable to benthic organisms in dynamic sediment environments.

TL;DR: The study indicated that the labile fraction of metals measured by DGT is useful for predicting metal toxicity to benthic invertebrates, supporting the applicability of this technique as a rapid monitoring tool for sediments quality assessments.
