“…Recently, there has been an increase in the application of nondestructive multielement methods for analysis of seafood samples [ 25 , 49 ]. Methods based on X-ray spectrometry such as X-ray fluorescence (XRF) [ 19 , 25 , 49 ], energy dispersion-XRF (ED-XRF) [ 19 ], proton induced X-ray emission (PIXE), total reflection X-ray fluorescence spectrometry (TXRF), and synchrotron X-ray fluorescence (SXRF), as well as methods based on X-ray microanalysis, offer several benefits [ 50 ]. Among these, the selective detection and sensitivity (about mg kg −1 and below) for most of the elements [ 12 , 49 ], minimal sample preparation, high sample throughputs, and accuracy in quantification are worth mentioning [ 50 ].…”

“…Laser-based techniques also play an important role for the direct analysis of solid samples and, in the last years, they have become increasingly present in the food industry. Laser-induced breakdown spectrometry (LIBS) is considered a promising micro-destructive food analysis tool for rapid qualitative and quantitative chemical analysis [ 50 , 51 ]. However, the direct analysis of samples with complex organic matrices such as fresh food products is not easy [ 50 ].…”

The demand for fish and seafood is growing worldwide. Meanwhile, problems related to the integrity and safety of the fishery sector are increasing, leading legislators, producers, and consumers to search for ways to effectively protect themselves from fraud and health hazards related to fish consumption. What is urgently required now is the availability of reliable, truthful, and reproducible methods assuring the correspondence between the real nature of the product and label declarations accompanying the same product during its market life. The evaluation of the inorganic composition of fish and seafood appears to be one of the most promising strategies to be exploited in the near future to assist routine and official monitoring operations along the supply chain. The present review article focuses on exploring the latest scientific achievements of using the multi-elemental composition of fish and seafood as an imprint of their authenticity and traceability, especially with regards to the geographical origin. The scientific literature of the last 10 years focusing on the analytical determination and statistical elaboration of elemental data (alone or in combination with methodologies targeting other compounds) to verify the identity of fishery products is summarized and discussed.

“…The minimal quantity of sample required to perform solid sampling techniques is beneficial in two aspects: (a) they are perfectly suited for rare samples where only small amounts are available, especially for most clinical and environmental samples, and (b) the option of spatial resolution to study bioavailability and metal distribution 4,19,20 . Studies of human hair, which is a good indicator of exposure to both toxicologically critical and essential elements, are an example, where the potential of both methods is widely applied 10,19,21 . Due to the low absolute amounts of elements of interest, for example, mercury, only methods providing low absolute limit of detection and quantification are capable of this type of analysis; thus, ETV/ICP‐MS and LA/ICP‐MS are advantageous 22–24 .…”

Rationale (Eco‐)toxicological effects are mostly derived empirically and are not correlated with metal uptake. Furthermore, if the metal content is determined, mostly bulk analysis of the whole organism population is conducted; thus, biological variability is completely disregarded, and this may lead to misleading results. To overcome this issue, we compared two different solid sampling techniques for the analysis of single organisms. Methods In this study, complementary electrothermal vaporization/inductively coupled plasma mass spectrometry (ETV/ICP‐MS) ⇔ laser ablation/inductively coupled plasma mass spectrometry (LA/ICP‐MS)‐based methods for the analysis of individual organisms were developed and the results obtained were compared with the concentrations obtained after digestion and measured using ICP‐MS. For this purpose, a common (eco‐)toxicological test organism, the mud shrimp Corophium volutator, was selected. As proof‐of‐concept application, these organisms were incubated with environmentally relevant metals from galvanic anodes, which are often used for protection against metal corrosion in, for example, offshore wind farms. Results The bulk analysis revealed that large quantities of the incubated elements were detectable. Using the ETV/ICP‐MS method, we could identify a high biovariability within the population of organisms tested. Using the LA/ICP‐MS method, it could be determined that the large quantities of the elements detected were due to adsorption of the metals and not due to uptake, which correlates well with the absence of (eco‐)toxicological effects. Conclusions The results obtained imply the efficiency of complementary methods to explain the absence or presence of (eco‐)toxicological effects. In particular, methods that allow for single‐organism analysis or provide even a spatial resolution support the interpretation of ecotoxicological findings.

Atomic absorption spectrometry (AAS) is a well‐established technique for the quantitative determination of elements in environmental materials at trace and ultratrace levels. AAS is an optical atomic spectrometric technique based on the measurement of the specific absorption originated from the free, unionized atoms in the gas phase. For transferring the analyte to free atoms, different types of atomizers are in use, out of which the flame and the graphite furnace are the most often used atomizers. Typical detection limits of flame AAS (FAAS) are of the order of 1–100 μg L −1 , making it a perfect tool for the determination of minor and trace elements, at least for contaminated samples. Graphite furnace AAS (GFAAS), offering detection limits which are about a factor of 20–200 lower than for FAAS, is the standard method for many trace elements especially for background values, and for unpolluted samples, such as freshwater and biological materials. AAS in its conventional configuration is a single element technique, which has to be used in a sequential mode when more than one element has to be determined. However, there are commercial instruments available, that can be used for the determination of six to eight elements simultaneously. While most manufacturers provide instruments working with line sources, one manufacturer has commercialized high‐resolution instruments working with continuum sources (HRCS‐AAS).
