“…[81,92,93,95,97] Utilising millisecond to microsecond dwell times, the count intensity arising from a single particle ablation event can be detected. This count intensity can then be converted into a mass using a calibration curve of dissolved standards that relate elemental mass to count intensity.…”

Environmental context. The detection and characterisation of engineered nanomaterials in the environment is essential for exposure and risk assessment for this emerging class of materials. However, the ubiquitous presence of naturally occurring nanomaterials presents a unique challenge for the accurate determination of engineered nanomaterials in environmental matrices. New techniques and methodologies are being developed to overcome some of these issues by taking advantage of subtle differences in the elemental and isotopic ratios within these nanomaterials.Abstract. The increasing manufacture and implementation of engineered nanomaterials (ENMs) will continue to lead to the release of these materials into the environment. Reliably assessing the environmental exposure risk of ENMs will depend highly on the ability to quantify and characterise these materials in environmental samples. However, performing these measurements is obstructed by the complexity of environmental sample matrices, physiochemical processes altering the state of the ENM and the high background of naturally occurring nanoparticles (NNPs), which may be similar in size, shape and composition to their engineered analogues. Current analytical techniques can be implemented to overcome some of these obstacles, but the ubiquity of NNPs presents a unique challenge requiring the exploitation of properties that discriminate engineered and natural nanomaterials. To this end, new techniques are being developed that take advantage of the nature of ENMs to discern them from naturally occurring analogues. This paper reviews the current techniques utilised in the detection and characterisation of ENMs in environmental samples as well as discusses promising new approaches to overcome the high backgrounds of NNPs. Despite their occurrence in the atmosphere and soil, this review will be limited to a discussion of aqueous-based samples containing ENMs, as this environment will serve as a principal medium for the environmental dispersion of ENMs.

The quantities of engineered nanoparticles (NP) released to the environment are often influenced by their fate in waste water treatment plants (WWTP). Here, 40 nm silver NP (AgNP) were spiked into a mesocosm simulating the process used at a major municipal WWTP. The evolution of the mass distributions and number concentrations were followed by fast acquisition speed technique single particle inductively coupled mass spectrometry (FAST spICP-MS) using a high-resolution ICP-MS. It was thus possible to detect smaller Ag containing NP than hitherto possible in similar studies. These small particles (ca. 5-10 nm in corresponding metallic Ag equivalent spherical diameter) were possibly dissolved Ag + precipitated as Ag 2 S particles. They were detected immediately upon spiking and were stable with respect to aggregation and thus much less removed by the WWTP process compared to the 40 nm AgNP. The results also suggested that any transformation of the latter AgNP occurred without dissolution. Most of these larger AgNP were probably removed by aggregation with large floc particles and subsequent sedimentation with the suspended particulate matter in the simulated WWTP process. The results have implications for differentiating the fate of nanoparticles as a function of size and demonstrate how spICP-MS can reveal such size-dependent fate dynamics. Environmental Significance StatementThe size distributions of Ag nanoparticles during simulated waste water treatment were followed by FAST spICP-MS. The high sensitivity allowed to detect particles with an Ag mass as small as ca. 5 nm in corresponding metallic Ag equivalent spherical diameter. These small particles were contrary to expectations stable with respect to aggregation with suspended particulate matter.

The use of nanoparticles (NP) has increased in these years. They are used in many fields, for example industrial and commercial sectors. The large employment may compromise the human and the ecosystem health, because the fate/damages/consequences of NP in the environment are still not known. SP-ICP-MS is a fast method and it can be used for a screening of environmental samples, it combines high sensitivity with fast analytical speed. This is a water surface study, few rivers in the North East of Italy are analysed. 3 litres of surface water are filtered with a vacuum pump with membrane by 0.22 µm pore. The filter is put into a test tube with 30 mL of ultrapure water and then sonicated for 20 minutes. The analyses are performed on a SP-ICP-MS NexION 350D Perkin Elmer using Syngistix Software. Transport efficiency and particle calibration are performed with standard gold nanoparticles of 30 nm, 60 nm and 90 nm. The detection limit (DL) is calculated from the analysis of 5 replicates of ultrapure water. The recovery test is made on water surface both spiked and unspiked and it appears to be between 61,8% and 97%. Considering the high dilution of NP in an environmental complex matrix, this study evaluates the efficiency of the concentration via filtration for SP-ICP-MS analysis of nanoparticles of ZnO, CeO 2 , TiO 2 , Ag. The results show that the analysis in SP-ICP-MS combined with the filtration enhance the detection sensitivity and the characterization of nanoparticles.
