“…This result is consistent with those reported by other researchers, who found higher levels of PCBs in eel muscle with respect to other species, attributable mainly to the high level of tissue fat peculiar to this species [24]. For this reason, eel is considered a bioindicator of PCB environmental pollution [37]. [45], and ppDDE = 10 ug/kg bw/d (FAO/WHO, 2000) [46].…”

The aim of our study was to describe the balance between health benefits and risks associated with the consumption of crawfish and nine fish species from lake Trasimeno. We thus determined both fatty acid profiles (particularly, eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids) and chemical pollutants (some polychlorinated biphenyls, pesticides, and heavy metals) in fish muscle tissues. The contents of all fatty acids varied significantly among species. Sand smelt, carp, and tench, which have a high fat content, contained considerable amounts of EPA and DHA; lean fish, like perch, pike, and largemouth bass, which have relatively high percentages of the predominant n-3 fatty acids EPA and DHA, showed lower amounts of these fatty acids because of their low lipid contents. Some species contributed strongly to the Dietary Reference Intake (RDI) of EPA and DHA. The contribution of lean fish to the RDI of EPA and DHA was more limited. The concentrations of all contaminants in fish muscle tissues were lower than the regulatory limits, demonstrating the safety of the environmental conditions of the lake. The contribution to health-based reference values and benefit–risk quotients indicated that the health benefits of consumption of fish from lake Trasimeno outweigh the potential risks.

“…Sediment-associated organisms, like marine bivalves and fish have been used to monitor pollution (Bettinetti et al, 2011;Bodin et al, 2014;Covaci et al, 2005;Roosens et al, 2010;Tapie et al, 2011). They are specific indicators of different environmental compartments in relation to their habitat and food web position, and they exhibit different rates of biotransformation and/or bioaccumulation with respect to xenobiotics (Livingstone, 1998;Scaps, 2002).…”

“…The highest contamination level concerned adult eels (silver eels) and was similar to Northern Europe contamination levels which raise sanitary problem for human consumption but also can affect eel sexual maturation. A study on PCB contamination in fish community from the Gironde estuary, confirmed the high concentration levels in eels and food web magnification (Bodin et al 2014).…”

The European sturgeon, Acipenser sturio, is a highly endangered species that almost disappeared in the last decades. Thanks to yearly restocking of the population, this species is still found in the Gironde estuary (France), where juveniles grow during several years before leaving to the ocean. The aim of this study was to evaluate the pressure exerted on these fish by known organic and inorganic contaminants during their stay at the Gironde estuary, and to get information on the fish's health in this context. Monthly captures over the year 2014, provided 87 fish from the cohorts 2012 and 2013 mainly, and from cohorts 2008, 2009 and 2011, all fish born in hatchery. We report the very first analyses of contaminant levels and of biological markers measured in the blood of these fish. Low inorganic contamination was found, composed of seven metals mainly: Zn (< 5 µg.mL-1), Fe (< 1.5 µg.mL-1), Cu (< 0.8 µg.mL-1), Se (< 0.8 µg.mL-1), As (< 0.25 µg.mL-1), Co (< 0.14 µg.mL-1) and Mn (< 0.03 µg.mL-1). Concerning persistent organic contaminants, the sum of 7 PCBs varied from 1 to 10 ng.g-1 plasma, that of 8 OCPs from 0.1 to 1 ng.g-1 , and that of 8 PBDEs from 10 to 100 pg.g-1. Higher levels of contaminants were measured during spring as compared to summer. The sex steroid hormone plasma levels (estradiol, testosterone and 11ketotestosterone) were quite low, which 2 was predictable for juveniles. The transcription of reproduction-involved genes (EstR, AR, LHR, sox9) in blood cells was demonstrated for the first time. Some of them were correlated to organic contaminant levels PCBs and OCPs. Other gene transcriptions (sodCu and bax) were correlated to PCBs and OCPs. However, the DNA damage level measured here as comet tail DNA and micronuclei ratio in red blood cells, were in the very low range of the values commonly obtained in fish from pristine areas. The data presented here can serve as a reference base for future monitoring of this population of sturgeons.
