Relevance of current PCB concentrations in edible fish species from the Mediterranean Sea

Persistent Organic Pollutants Burden, Trophic Magnification and Risk in a Pelagic Food Web from Coastal NW Mediterranean Sea

“…For PBDEs and PCDD/Fs, which exhibited more nd values, only congeners with >30% detection frequency and detected in at least seven different species and plankton size-classes were considered for the TMF calculation. In order to derive the estimated weekly intake (EWI) of DL POPs and ∑PBDEs (Section ), the weekly consumption data for France for demersal ( M. merluccius) and pelagic (rest of species) fish and cephalopod (222, 132, and 9.2 g/week, respectively) were multiplied by the WHO 05 -TEQ (PCDD/Fs + DL PCBs) and the ∑PBDEs (only detected values) concentration, respectively, measured in the corresponding species and divided by 70 kg (average human bodyweight, bw), as previously described . Risk quotients ( R ), were calculated as the concentration in the sample and its corresponding EWI, to threshold values, legally binding or not, derived by international authorities to protect humans consuming fishery products and aquatic ecosystems ( R > 1 indicating risk).…”

“…The chemical contamination of the marine environment is a global and transversal issue with important ecological and socio-economic implications, yet not well quantified nor efficiently managed. , Populations living in coastal areas, as well as marine organisms, are exposed to multiple sources of chemical contamination, particularly in semienclosed environments such as the Mediterranean Sea. The Mediterranean is a sensitive environment with the particularity of being a hotspot of both marine biodiversity (up to 18% of the world’s marine diversity) and chemical contamination (e.g., organic and inorganic contaminants, plastic debris). − Among the contaminants impacting this marine environment, persistent organic pollutants (POPs) and related chemicals are well documented in nonbiotic compartments − and different marine organisms. ,,− POPs are organic contaminants of major concern due to their high toxicity, long-range transport and bioaccumulation potential, and their high resistance to degradation . Even if these toxic chemicals have been banned by international regulations, such as the Stockholm Convention on POPs (SC), their ubiquity in the marine environment many years after their release may still pose potential risks.…”

Polychlorinated dioxins, furans (PCDD/Fs) and dioxin‐like polychlorinated biphenyls (dl‐PCBs) in food from Italy: Estimates of dietaryintake and assessment

“…The food monitoring studies on PCDD/Fs and PCBs in various European Countries have been performed in the last decades (Marin et al., 2011 ; Perelló et al., 2012 ; Quijano et al., 2018 ; Sirot et al., 2012 ; Törnkvist et al., 2011 ; Windal et al., 2010 ) until now (Hulin et al., 2020 ), but to the best of our knowledge, currently available data about the dietary exposure in Italian population are rather limited (Fattore et al., 2008 ; Fattore et al., 2006 ; Taioli et al., 2005 ; Turci et al., 2006 ) and often dedicated merely to a few dietary components (Barone et al., 2019 ; Ghidini et al., 2005 ; Grassi et al. 2010 ; Esposito et al., 2020 ; Bartalini et al., 2020 ; Castellani et al., 2021 ).…”

Assessment of Perceptions and Cancer Risks of Workers at a Polychlorinated Biphenyl-Contaminated Hotspot in Ethiopia

“… 18 Furthermore, PCBs were detected in the muscle of edible fish species such as sardine (4.15–17.9, ng/g w.w.), anchovy (1.01–7.08 ng/g w.w.) and bogue (1.46–7.22 ng/g w.w.) in the Mediterranean Sea. 19 The United States Environmental Protection Agency (USEPA) toxicological reference values for PCBs in food, water and air are 3 ppm, 5E-4 and 1 mg/m 3 respectively. 20 Humans can also be exposed to PCBs via occupational practices.…”
