Contamination by organophosphate flame retardants (OPFRs) is an emerging concern in aquatic environments. Concentrations of 18 OPFRs were measured in water and sediments collected from the artificial Lake Shihwa. OPFR concentrations in sediments measured in this study were the highest reported worldwide, implying severe OPFR contamination. The highest concentrations of OPFRs were found in creeks taken near industrial complexes, and OPFR concentrations decreased with increasing distance from creeks to inshore or offshore lake waters. On-going OPFR contamination by wastewater treatment plant (WWTP) discharge was evidenced by the clear decrease in OPFRs in water samples collected moving away from WWTP outfall. TBEP and TEP were dominant in water samples, while TDCPP and TCPP were dominant in sediment samples. Differences in contamination profiles with sample matrices are likely due to hydrophobicity of individual OPFRs. Non-parametric multidimensional scaling ordination showed that OPFR contamination was affected by pollution inflow and proximity to industrial complexes.
水体中有机磷酸酯阻燃剂（OPFRs）的污染是一个新出现的环境问题。本研究在石湖采集的水样和沉积物中检测到了 18 种 OPFRs，其浓度水平为全球最高，表明该地区存在严重的 OPFR 污染。在靠近工业综合体的溪流中检测到的 OPFRs 浓度最高，并且随着与溪流的距离增加，OPFRs 的浓度从近岸或近海湖水中逐渐降低。污水处理厂（WWTP）排放的持续 OPFR 污染可通过远离 WWTP 出水口的水样中 OPFRs 浓度的明显降低得到证明。TBEP 和 TEP 在水样中占主导地位，而 TDCPP 和 TCPP 在沉积物样品中占主导地位。由于个体 OPFRs 的疏水性，不同样本基质的污染特征存在差异。非参数多维尺度排序表明，OPFR 污染受到污染物流入和靠近工业综合体的影响。
