合成麝香作为一种新兴的污染物，由于其在生物群中的生物积累而引起了世界范围的关注。然而，SMs在生物群中的环境命运却知之甚少。本研究首次揭示了SMs在可食生物群（鱼和芦荟）中的吸收和消除行为以及转移能力。鱼类肌肉对SMs的积累效率约为芦荟叶片的100-2000倍，在生物群中，硝基麝香比多环麝香具有更高的生物积累潜力。此外，芦荟根系吸收的SMs转移能力较差。本研究还发现，积累在生物群中的硝基麝香和多环麝香在清洁水中均表现出优异的去除率，在鱼类（3 d）和芦荟（2 d）中去除率分别大于78%和80%。此外，计算结果表明，SMs可能具有化学增敏剂的作用，并增加了实际水生环境中生物群中通常排除的有毒物质的积累。
As emerging contaminants, synthetic musks (SMs) cause worldwide concern due to their bioaccumulation in biota. However, the environmental fates of SMs in biota are poorly understood. Here, for the first time, the uptake and elimination behaviors, as well as the transferable capacities, of SMs in living edible biota (fish and aloe) were revealed. Fish muscle was approximately 100–2000 times more efficient in accumulating SMs than was aloe leaf, and nitro musks showed a higher bioaccumulation potential than did polycyclic musks in biota. In addition, the transferable capabilities of SMs by root uptake in aloe were poor. This investigation also showed that both nitro musks and polycyclic musks that accumulated in biota exhibited excellent elimination rates in clean water, and the elimination rates were greater than 78% and 80% in fish (3 d) and aloe (2 d), respectively. Furthermore, the calculated results suggest that SMs might act as chemosensitizers and enhance the accumulation of normally excluded toxicants in biota in a real aquatic environment.
