Nanotechnology offers substantial prospects for the development of state-of-the-art products and applications for agriculture, water treatment, and food industry. Profuse use of nanoproducts will bring potential benefits to farmers, the food industry, and consumers, equally. However, after end-user applications, these products and residues will find their way into the environment. Therefore, discharged nanomaterials (NMs) need to be identified and quantified to determine their ecotoxicity and the levels of exposure. Detection and characterization of NMs and their residues in the environment, particularly in food and agricultural products, have been limited, as no single technique or method is suitable to identify and quantify NMs. In this review, we have discussed the available literature concerning detection, characterization, and measurement techniques for NMs in food and agricultural matrices, which include chromatography, flow field fractionation, electron microscopy, light scattering, and autofluorescence techniques, among others.

“…In parallel, the appropriateness of the available methodologies for risk assessment of ENMs, including analytical methods, was brought into question [5,6]. In the following years, a number of revision articles were published, summarizing the state of the art of analytical methods with respect to the detection, characterization and quantification of engineered nanoparticles [7][8][9][10][11][12][13][14][15][16][17][18][19] or focussing on specific techniques, like electron microscopy [20], inductively coupled plasma mass spectrometry [21], light scattering [22], particle tracking analysis [23] or field flow fractionation [24][25][26]. Most of the general reviews listed advantages and potential limitations, and even proposed approaches and techniques with high potential to overcome already detected as well as expected problems.…”

The increasing demand of analytical information related to inorganic engineered nanomaterials requires the adaptation of existing techniques and methods, or the development of new ones.The challenge for the analytical sciences has been to consider the nanoparticles as a new sort of analytes, involving both chemical (composition, mass and number concentration) and physical information (e.g. size, shape, aggregation). Moreover, information about the species derived from the nanoparticles themselves and their transformations must also be supplied. Whereas techniques commonly used for nanoparticle characterization, such as light scattering techniques, show serious limitations when applied to complex samples, other well-established techniques, like electron microscopy and atomic spectrometry, can provide useful information in most cases. Furthermore, separation techniques, including flow field flow fractionation, capillary electrophoresis and hydrodynamic chromatography, are moving to the nano domain, mostly hyphenated to inductively coupled plasma mass spectrometry as element specific detector.Emerging techniques based on the detection of single nanoparticles by using ICP-MS, but also coulometry, are in their way to gain a position. Chemical sensors selective to nanoparticles are in their early stages, but they are very promising considering their portability and simplicity.Although the field is in continuous evolution, at this moment it is moving from proofs-of-2 concept in simple matrices to methods dealing with matrices of higher complexity and relevant analyte concentrations. To achieve this goal, sample preparation methods are essential to manage such complex situations. Apart from size fractionation methods, matrix digestion, extraction and concentration methods capable of preserving the nature of the nanoparticles are being developed. This review presents and discusses the state-of-the-art analytical techniques and sample preparation methods suitable for dealing with complex samples. Single-and multimethod approaches applied to solve the nanometrological challenges posed by a variety of stakeholders are also presented.

Using the ionic liquid (IL) 1-octyl-3-methylimidazolium hexafluorophosphate as the extractant and methanol as the dispersion solvent, a dispersive liquid-liquid microextraction method was developed to extract silver nanoparticles (AgNPs) from environmental water samples.Parameters that influenced the extraction efficiency such as IL concentration, pH and extraction time were optimized. Under the optimized conditions, the highest extraction efficiency for AgNPs was above 90% with an enrichment factor of >90. The extracted AgNPs in the IL phase were identified by transmission electron microscopy and ultraviolet-visible spectroscopy, and quantified by inductively coupled plasma mass spectrometry after microwave digestion, with a detection limit of 0.01 μg/L. The spiked recovery of AgNPs was 84.4% with a relative standard deviation (RSD) of 3.8% (n = 6) at a spiked level of 5 μg/L, and 89.7% with a RSD of 2.2% (n = 6) at a spiked level of 300 μg/L, respectively. Commonly existed environmental ions had a very limited influence on the extraction efficiency. The developed method was successfully applied to the analysis of AgNPs in river water, lake water, and the influent and effluent of a wastewater treatment plant, with recoveries in the range of 71.0%-90.9% at spiking levels of 0.11-4.7 μg/L. IntroductionSilver nanoparticles (AgNPs) have been applied in various products, such as plastics, household textiles, medicine, and cosmetics, due to their excellent antimicrobial properties (Benn and Westerhoff, 2008;Blaser et al., 2008;Emam et al., 2013;Meyer et al., 2011;Quadros and Marr, 2011;Sondi and Salopek-Sondi, 2004;Shahverdi et al., 2007;Sallum et al., 2014;Tolaymat et al., 2010). As a result, AgNPs can be released into the environment, and result in potential risk to human beings and other biological organisms Khan et al., 2011;Losert et al., 2014;Sharma et al., 2014;Tian et al., 2013;Yu et al., 2012). It was reported that orally delivered AgNPs induced deleterious effects on the liver and heart for mammals (Elle et al., 2013). Additionally, AgNPs could accumulate and transport along the food chain (Zhao and Wang, 2010). However, the mechanism of AgNP toxicity is not clear, although it was reported that the morphological A v a i l a b l e o n l i n e a t w w w . s c i e n c e d i r e c t . c o m ScienceDirect w w w . e l s e v i e r . c o m / l o c a t e / j e s characteristics such as surface charge, particle size and shape were related to their toxicity (Badawy et al., 2011;Burkowska-But et al., 2014;Carlson et al., 2008;Pal et al., 2007). This lack of knowledge could be ascribed to the complexity of nanoparticles themselves, as well as the lack of methods that are capable of monitoring the trace AgNPs from complex environmental and biological samples without disturbing their characteristics (Farré et al., 2011).4 1 ( 2 0 1 6 ) 2 1 1 -2 1To date, several methods have been developed for the separation and determination of AgNPs such as field flow fractionation, anodic particle coulometry, and hydrodynamic chromato...
