Classic (polybromodiphenyl ethers, PBDEs) and emerging halogenated flame retardants (HFRs) such as decabromodiphenyl ethane (DBDPE) and halogenated norbornenes, as well as organophosphate flame retardants (OPFRs) were analysed in 52 sediments and 27 fish samples from three European river basins, namely the Evrotas (Greece), the Adige (Italy) and the Sava (Slovenia, Croatia, Bosnia and Herzegovina and Serbia). This is the first time that FR levels have been reported in these three European river basins. The highest contamination was found in the Adige and Sava rivers, whereas lower values were obtained for the Evrotas. The levels in sediment samples ranged between 0.25 and 34.0ng/g dw, and between 0.31 and 549ng/g dw, for HFRs and OPFRs respectively. As regards levels in fish, concentrations ranged between 9.32 and 461ng/g lw and between 14.4 and 650ng/g lw, for HFRs and OPFRs, respectively. Thus, whereas OPFR values were higher in sediments, similar concentrations (in the Evrotas) and even lower concentrations than HFRs (Sava) were found for OPFRs in the fish samples, indicating the lower bioaccumulation potential of OPFRs. Biota to sediment accumulation factors (BSAFs) were calculated and higher values were obtained for HFRs compared to those assessed for OPFRs.
在来自欧洲三个流域（即埃夫罗塔斯河（希腊）、阿迪杰河（意大利）和萨瓦河（斯洛文尼亚、克罗地亚、波斯尼亚和黑塞哥维那以及塞尔维亚）的 52 个沉积物和 27 个鱼类样本中分析了经典（多溴二苯醚，PBDEs）和新兴卤代阻燃剂（HFRs），如十溴二苯乙烷（DBDPE）和卤代降冰片烯，以及有机磷酸酯阻燃剂（OPFRs）。这是首次在这三个欧洲流域报告 FR 水平。阿迪杰河和萨瓦河的污染最为严重，而埃夫罗塔斯河的污染程度较低。沉积物样本中的 HFRs 和 OPFRs 含量分别在 0.25 至 34.0ng/g dw 和 0.31 至 549ng/g dw 之间。就鱼类样本而言，HFRs 和 OPFRs 的浓度分别在 9.32 至 461ng/g lw 和 14.4 至 650ng/g lw 之间。因此，虽然 OPFR 在沉积物中的含量较高，但在鱼类样本中，OPFR 的浓度与 HFRs 相似（在埃夫罗塔斯河）甚至比 HFRs （萨瓦河）低，这表明 OPFR 的生物蓄积潜力较低。计算了生物群到沉积物的积累因子（BSAFs），与 OPFRs 相比，HFRs 的 BSAFs 更高。
