Contamination by classic (polybromodiphenyl ethers, PBDEs) and emerging halogenated flame retardants (HFRs) like pentabromobenzene (PBEB), hexabromobenzene (HBB), decabromodiphenyl ethane (DBDPE), and halogenated norbornenes (HNs), as well as organophosphate flame retardants (OPFRs) were investigated in sediment and eel (Anguilla Anguilla) samples from Bizerte Lagoon, northern Tunisia. For sediment samples, HFR levels ranged from 3.30 to 28.5 ng/g dry weight (dw), with a mean value of 10.6 ± 4.36 ng/g dw, while OPFR levels ranged between 9.77 and 164 ng/g dw, with a mean value of 53.6 ± 10.5 ng/g dw. As regards levels in fish, concentration of HFRs ranged between 4.72 and 151 ng/g lipid weight (lw) (mean value of 36.5 ± 28.5 ng/g lw), and OPFR levels ranged between 19.7 and 2,154 ng/g lw (mean value of 404 ± 367 ng/g lw). This is the first time that OPFR levels have been reporting in this area, being higher than those for HFRs. Statistical analysis of the relationship between OPFR and HFR concentrations in sediment and total organic carbon (TOC) was examined. Results suggested that OPFR levels were significantly correlated with TOC, whereas no correlation was found for HFRs and TOC. The health risk associated by the consumption of eel in Bizerte city was assessed and posed no threat to public health concerning PBDE and OPFR intakes.

突尼斯比塞大泻湖的沉积物和鳗鱼（Anguilla anguilla）中卤化和有机磷阻燃剂的存在

经典（多溴二苯醚、PBDE）和新兴卤化阻燃剂（HFR）如五溴苯（PBEB）、六溴苯（HBB）、十溴二苯乙烷（DBDPE）和卤化降冰片烯（HN）以及有机磷阻燃剂（OPFR）的污染对来自突尼斯北部比塞大泻湖的沉积物和鳗鱼（安圭拉安圭拉）样本进行了研究。对于沉积物样品，HFR 水平介于 3.30 至 28.5 ng/g 干重 (dw) 之间，平均值为 10.6 ± 4.36 ng/g dw，而 OPFR 水平介于 9.77 至 164 ng/g dw 之间，平均值为53.6 ± 10.5 纳克/克干重。至于鱼类中的水平，HFR 的浓度介于 4.72 和 151 ng/g 脂重 (lw) 之间（平均值为 36.5 ± 28.5 ng/g lw），而 OPFR 的浓度介于 19.7 和 2,154 ng/g lw 之间（平均值404 ± 367 ng/g lw）。这是该领域首次报告 OPFR 水平，高于 HFR 的水平。检查了沉积物中 OPFR 和 HFR 浓度与总有机碳 (TOC) 之间关系的统计分析。结果表明，OPFR 水平与 TOC 显着相关，而 HFR 和 TOC 没有相关性。对比塞大市食用鳗鱼的健康风险进行了评估，在 PBDE 和 OPFR 摄入量方面未对公众健康构成威胁。而没有发现 HFR 和 TOC 的相关性。对比塞大市食用鳗鱼的健康风险进行了评估，在 PBDE 和 OPFR 摄入量方面未对公众健康构成威胁。而没有发现 HFR 和 TOC 的相关性。对比塞大市食用鳗鱼的健康风险进行了评估，在 PBDE 和 OPFR 摄入量方面未对公众健康构成威胁。
