Synthetic musk compounds are extensively used in personal care and cosmetic products all over the world. Afterwards, they are discharged into the environment mainly because they are not completely removed in wastewater treatment plants. The aim of this study was to investigate if a passive sampler is applicable for the monitoring of tonalide, a polycyclic musk compound, in the aquatic environment and to compare the levels of tonalide in pesticide-polar organic chemical integrative sampler (POCIS) and biota. For this purpose, four sampling localities on the three biggest rivers in the Czech Republic were selected. Tonalide was determined in POCIS at all sampling sites in the concentration ranging from 9 ng/POCIS (Labe River, Hradec Králové) to 25 ng/POCIS (Morava River, Blatec). The locality with the most frequent occurrence of tonalide in biota samples was the Morava River which well corresponded with the highest tonalide concentration in POCIS among sampling sites. The highest number of positive tonalide detections among all studied biota samples was found in fish plasma. To the best of our knowledge, this is the first evidence that tonalide bioaccumulates in fish blood. Tonalide levels were below the limit of quantification in benthos samples at all sampling sites.
合成麝香化合物在世界各地的个人护理和化妆品产品中广泛使用。之后，它们主要因为在废水处理厂中没有被完全去除而被排放到环境中。本研究的目的是调查被动采样器是否适用于监测多环麝香化合物 tonalide 在水环 境中，并比较农药-极性有机化学综合采样器（POCIS）和生物群中 tonalide 的水平。为此，在捷克共和国的三条最大河流的四个采样地点进行了选择。在所有采样地点，POCIS 中的 tonalide 浓度范围从 9ng/POCIS（拉贝河，赫拉德茨克拉洛韦）到 25ng/POCIS（摩拉瓦河，布拉迪斯拉发）。在生物群样本中 tonalide 出现最频繁的地点是摩拉瓦河，这与采样地点中 POCIS 中 tonalide 的最高浓度非常吻合。在所研究的所有生物群样本中，鱼类血浆中发现的 tonalide 阳性检出数最高。据我们所知，这是 tonalide 在鱼类血液中生物积累的第一个证据。在所有采样地点，底栖样本中的 tonalide 水平均低于定量限。
