“…In the group of species showing higher ∑PBDE median concentrations (i.e., S. sarda , S. colias , T. trachurus , T. mediterraneus , and T. sagittatus ), the PBDE pattern was characterized mostly by the predominance of BDE-47 and -100 (32–46% and 13–31% of the detected ∑PBDEs, respectively) and a lower contribution of PBDE-209 (4–16% of the detected ∑PBDEs) (SI Figure S11A). The predominance of these congeners, particularly BDE-47, has been reported for other marine organisms. ,, Furthermore, the patterns in M. merluccius and I. coindetii , two out of the three species showing the lowest median values, showed a more even relative distribution of BDE-47 and BDE-209, accounting for the 24–32 and 32–39% of the detected ∑PBDEs, respectively (SI Figure S11B). These are piscivorous and invertivorous species feeding mainly on pelagic species.…”

“…This threshold value was exceeded in every single individual in all TLs (SI Table S14), indicating a risk for humans consuming the edible species, again pointing to S. sarda ( R = 54–97) and S. colias ( R = 15–65) as the most “risky” fish. However, some authors argue that the existing EQS Biota for PBDEs is extremely low leading to environmental concentrations exceeding the threshold value in most study cases. , For OSPAR, there are still questions on the reliability and appropriateness of some of the thresholds set as EQS biota , based on human protection, to support environmental assessment. This issue has recently resulted in the proposal to adopt the Canadian Federal Environmental Quality Guidelines (FEQGs) based only on wildlife protection .…”

The storage capacity, trophic magnification and risk of sixty-two POPs have been evaluated in a well-characterized pelagic food web (including phytoplankton, zooplankton, six fish, and two cephalopods species) from an impacted area in NW Mediterranean Sea. Our results show the high capacity of the planktonic compartment for the storage of polybrominated diphenyl ethers (PBDEs) and polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), consistent with their estimated low trophic magnification factors (TMF) of 0.2–2.0 (PBDEs) and of 0.3–1.1 (PCDD/Fs). ∑PBDEs dominated in the zooplankton size-class 200–1000 μm (∼330 ng g–1 lw, median), whereas ∑PCDD/Fs accumulated preferentially in phytoplankton size-class 0.7–200 μm (875 pg g–1 lw, median). In contrast, polychlorinated biphenyls (PCBs) were preferentially bioaccumulated in the higher trophic levels (six fish species and two cephalopods) with TMFs = 0.8–3.9, reaching median concentrations of 4270 and 3140 ng g–1 lw (∑PCBs) in Atlantic bonito (Sarda sarda) and chub mackerel (Scomber colias), respectively. For these edible species, the estimated weekly intakes of dioxin-like POPs for humans based on national consumption standards overpassed the EU tolerable weekly intake. Moreover, the concentrations of nondioxin-like PCBs in S. sarda were above the EU maximum levels in foodstuffs, pointing to a risk. No risk evidence was found due to consumption of all other edible species studied, neither for PBDEs. The integrated burden of POPs in the food web reached ∼18 μg g–1 lw, representing a dynamic stock of toxic organic chemicals in the study area. We show that the characterized food web could be a useful and comprehensive “bioindicator” of the chemical pollution status of the study area, opening new perspectives for the monitoring of toxic chemicals in Mediterranean coastal waters.

Accumulation of pesticides has a harmful impact on the environment and human health. The main goal of this work was to develop a method to determine and quantify the residues of thirteen pesticides in edible fish and bivalves such as parati (Mugil curema), seabass (Centropomus ssp.), mullet (Mugil brasiliensis), clams (Anomalocardia brasiliana) and mussel (Mytilus galloprovincialis) collected from Sepetiba Bay and Parnaiba River Delta (Brazil) between 2019 and 2020. Matrix solid-phase dispersion (MSPD) was used for extraction and quantification through gas chromatography coupled to tandem mass spectrometry (GC-MS/MS). The method was validated (linearity, accuracy and precision) for fatty fish (Salmo salar), lean fish (Mugil curema) and bivalves (Mytilus edulis). The survey found linear correlation coefficients (r) equal to or greater than 0.9 for almost all analytes. The relative standard deviations (RSD) of five replicates were less than 20% for almost all analytes at different concentrations in lean fish, fatty fish and bivalves. Most analytes showed satisfactory accuracy. Alachlor herbicide was found in samples of seabass, mussels, clams and parati with levels ranging between 0.55 to 420.39 μg kg−1 dw. Ethion was found in parati (maximum 211.22 μg kg−1 dw), mussels (15.1 μg kg−1 dw) and clams (maximum 44.50 μg kg−1 dw). Alachlor was found in clams (maximum 93.1 μg kg−1 dw), and bifenthrin was found in parati (maximum 43.4 μg kg−1 dw) and clams (maximum 42.21 μg kg−1 dw). The validated method was satisfactory for the determination of eleven pesticides in the fatty fish matrix, and thirteen pesticides in the samples of lean fish and bivalves. The presence of alachlor, ethion and bifenthrin stands out.
