“…However, it does not explain the exception we observed for Pb. Nonetheless, in direct comparison, our results were similar to those found by Sofoulaki et al (2018) on individuals collected from six Greek sites (Mediterranean Sea), with higher levels of most of the study trace elements observed in anchovies versus sardines, with the exception of Pb (i.e. same as the inverse trend found in our study).…”

“…Therefore, these processes could lead to a dilution of the contaminant concentration with growth. However, it has been observed that the negative correlation between metal concentrations and body size occurs when the marine pollution is at low levels; for high levels of pollution, instead, a positive correlation has been described (Sofoulaki et al 2018 ).…”

“…It has been described that the metal bioaccumulation is strongly influenced by metabolism in fish (Canli and Atli 2003). Hence, same authors have been suggested that the negative correlation is probably due to a faster metabolism rate of the smaller animals, which correspond to the younger specimens, than the older ones (Sofoulaki et al 2018). Therefore, these processes could lead to a dilution of the contaminant concentration with growth.…”

This study assesses the PAH and heavy metal levels in muscle of warty crabs (Eriphia verrucosa), from the northern coast of the Campania region improving the data on toxic contaminants in this crustacean. The results showed a minimal PAH contamination; the mean concentrations were as follows: 0.2, 1.6 and 1.7 μg kg-1 wet weight (ww) for BaP, PAH4 and PAH6, respectively. Regarding the levels of the two PAHs not included in the European regulations, the BkF mean concentration was 0.1 μg kg-1 ww, while DahA was detected only in 10.7% of samples. Pb and Cr were also detected at low levels with mean values of 0.068 and 0.468 mg kg-1 ww, respectively; instead, high As levels, with a mean value of 5.021 mg kg-1 ww, were found. Considering the EWIs and the ILCRs calculated in this study, the PAH, Pb and Cr contamination levels found in the edible part of the crabs resulted safe for human consumption. Contrariwise, the ILCR calculated for the As exceeded the acceptable level of cancer risk, although the calculation did not refer to the inorganic form which is the only one recognized as carcinogenic. Hence, this study shows that warty crabs can accumulate environmental contaminants in their muscle tissue representing an important route of exposure to these toxics for the local population that regularly consumes them. This finding highlights the importance of monitoring the presence of these pollutants in crabs and in general in all fish and seafood in order to ensure food safety for consumers.

“…Very few studies have investigated the concentrations of such a diversity of essential elements in such a variety of marine species -encompassing whole crustaceans, cephalopod mollusks and both cartilaginous and bony fish -as in the present study (Asante et al 2008, Cipro et al 2018. Studies reporting essential element concentrations in marine organisms indeed generally focus 1) on a quite limited number of species (< 10) or on a particular taxon or group of species (Fowler 1986, Ridout et al 1989, Naeem et al 2011, Sofoulaki et al 2018, Chouvelon et al 2019, Figueiredo et al 2020; 2) on specific tissues (i.e. human-edible tissues such as the muscle, Figure 4.…”

By transferring energy and nutrients from plankton to top predators, forage species play a major ecological role in marine food webs. While large differences in energy densities have been demonstrated among these species, other determinants of their quality remain poorly explored. We analysed 78 forage species from the Bay of Biscay, NE Atlantic, for their concentrations in various chemical elements with a documented biological role (i.e. micro-nutrients). Species encompassed jellyfish, crustaceans, cephalopods, cartilaginous and bony fish. Elements included two essential macro-minerals (nitrogen and phosphorous) and nine trace elements (arsenic (As), cobalt, copper (Cu), chromium, iron, manganese, nickel, selenium (Se), zinc). We showed a broad range of elemental composition values across forage species, partly driven by taxonomy (fish versus crustaceans/cephalopods) or their habitat (coastal versus oceanic, pelagic versus benthic). Some elements (As, Cu or Se) were more variable than others, especially in fish for Cu and Se. The 78 forage species were then classified by hierarchical clustering analysis (HCA) into different nutritional groups, based on their composition in eleven elements. Mean concentrations of each element in the diet of eight cetacean species was finally calculated, as well as the importance of each nutritional group (as defined by HCA including all elements) for each predator species. We revealed contrasting diets in terms of exposure to elements. Neritic common dolphins and harbour porpoises but also minke whales were thus mainly supplied by the Se-enriched nutritional group composed of small (pelagic) schooling fish (including sandeels, (horse) mackerel and also some Clupeids), while the diets of pilot whales or Risso's dolphins that mostly consume benthic cephalopods were clearly Cu-enriched. This study raises the issue of essential element composition as another determinant of food quality, and the risk associated with changes in forage species' availability for the proper functioning of marine food webs and ecosystems.
