Seven typical synthetic musks (SMs) in the samples from the surface water, sediment and fish of the Haihe River were measured. The SM concentrations in the sediment and surface water of the Haihe River were significantly lower than those in the Dagu Drainage River and Chentaizi Drainage River (p<0.05). Along the flow direction, the SM concentrations in surface water and sediment tended to increase from the upstream to the downstream of Dagu Drainage River. The Bioaccumulation factors (BAFs) of galaxolide (HHCB) and tonalide (AHTN) were calculated at high levels in the muscles of crucian carp, common carp, and silver carp. Most of the biota-sediment accumulation factors (BSAFs) for HHCB and AHTN were higher than 1.7, suggesting magnification possibly exist in the musk bioaccumulations of the three fishes in the Haihe River. No significant differences in HHCB/AHTN ratios were observed among the water, fish, and sediment samples (p>0.05). However, the HHCB/AHTN values in the Haihe River were much lower than those in the Dagu Drainage River and Chentaizi Drainage River (p<0.05). Compared with several typical persistent organic pollutants (POPs), the musk concentrations were higher or comparable in the Haihe River.
对海河表层水、沉积物和鱼类样品中的 7 种典型合成麝香（SMs）进行了测定。海河沉积物和表层水中的 SM 浓度明显低于大沽排水河和陈台子排水河（p<0.05）。沿水流方向，大沽排水河表层水和沉积物中的 SM 浓度有从上游到下游增加的趋势。鲫鱼、鲤鱼和草鱼肌肉中环己酮麝香（HHCB）和乙酰基甲酮麝香（AHTN）的生物积累因子（BAFs）较高。HHCB 和 AHTN 的大多数生物 - 沉积物积累因子（BSAFs）均高于 1.7，表明海河三种鱼类的麝香生物积累可能存在放大效应。水、鱼和沉积物样品中的 HHCB/AHTN 比值无显著差异（p>0.05）。然而，海河的 HHCB/AHTN 值远低于大沽排水河和陈台子排水河（p<0.05）。与几种典型的持久性有机污染物（POPs）相比，海河的麝香浓度较高或相当。
