| Abstract | Polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) and dioxin-like polychlorinated biphenyls (DL-PCBs) in fish samples have been investigated in many previous studies. However, the available data regarding this issue in low- and middle-income countries are very scarce, and no study has been performed in Algeria yet. Therefore, this work aimed to determine the levels of PCDD/Fs and DL-PCBs in swordfish (Xiphias gladius) caught in three regions of the Algerian coasts, and the health risk associated with these contaminants was assessed. The PCDD/Fs and DL-PCBs were analyzed in 37 fish samples from Algiers, Bejaia, and Oran using the DR-CALUX bioassay method. The overall mean (and standard deviation) of PCDD/Fs and DL-PCBs concentrations in swordfish from Algiers, Bejaia, and Oran were 0.19 (0.13), 0.27 (0.24), and 0.08 (0.05) pg TEQ g−1 wet weight (ww), respectively, which were lower than the national and European regulatory limits. Daily and weekly intake values of PCDD/F and DL-PCB were higher for the samples from Bejaia (0.45 and 3.15 pg TEQ kg−1 body weight (bw) per day and week, respectively) and for the samples from Algiers (0.31 and 2.17 pg TEQ kg−1 bw per day and week, respectively), which were higher than the tolerable weekly intake of 2 pg TEQ kg−1 bw per week recently established by the European Food Safety Authority. Overall, our findings indicate that swordfish consumption poses a risk to the Algerian consumer. |
