-----摘要:-------------------------------------------------------------------------------------------

采用UPLC-MS/MS法,研究了阿维菌素泼洒用药后,该药物在水体、底泥、伊乐藻(Elodea nuttallii)和水产动物体内的蓄积与消除规律。结果显示,以6μg/L浓度单次泼洒用药后,水体中阿维菌素消解较快,其半衰期为63.8 h。阿维菌素在养殖水环境中消减的同时,逐渐由水体向底泥、伊乐藻和水产动物迁移。底泥中阿维菌素峰浓度、曲线下面积和半衰期分别为1.25μg/kg、469.2μg/(kg·h)和115.5 h,说明伊乐藻中的相应值分别为8.75μg/kg、2521.7μg/(kg·h)和315.0 h,说明伊乐藻对阿维菌素有明显的吸收和富集作用。该模拟系统中的异育银鲫(Carassius auratus gibelio)对阿维菌素具有明显的吸收,其血液、肾、鳃、肝和肌肉组织阿维菌素的最高浓度(Cmax)依次为50.9、45.37、21.25、15.47和11.9μg/kg;而该模拟系统中的中华绒螯蟹(Eriocheir sinensis)仅鳃组织检出阿维菌素,其Cmax在12 h为8.08μg/kg,血淋巴、肌肉和肝胰腺等组织均未检出阿维菌素。生物富集系数FBC值显示,对阿维菌素的富集浓度由高到低依次为鲫鱼、伊乐藻、中华绒螯蟹、底泥,显示阿维菌素在不同分配相和不同生物组织的富集作用差异较大。

Ultra-performance liquid chromatography tandem mass-spectrometry was used to study the environmental behavior of avermectin (AVM) in a simulated aquaculture pond ecosystem. AVM degradation in water, as well as the accumulation and elimination of AVM in sediments, Elodea nuttallii, and fish and crab tissues were explored. The results showed that 6 μg/L AVM had a half-life of 63.8 h in the simulated pond. At the same time, AVM was transferred to the sediment, E. nuttallii, and aquatic animals. The peak AVM concentration, concentration time curve, and half-life in sediment were 1.25 μg/kg, 469.2 μg/(kg·h), and 115.5 h, respectively. The corresponding values in E. nuttallii were 8.75 μg/kg, 2521.7 μg/(kg·h), and 315.0 h, respectively. These results indicate that AVM was absorbed and enriched in E. nuttallii. In the simulated system, crucian carp (Carassius auratus gibelio) absorbed AVM from water, and peak blood, kidney, gill, liver, and muscle concentrations were 50.9 μg/kg, 45.37 μg/kg, 21.25 μg/kg, 15.47 μg/kg, and 11.9 μg/kg, respectively. AVM was only detected in the gill of Chinese mitten crab (Eriocheir sinensis) at a peak concentration of 8.08 μg/kg but was not detected in hemolymph, muscle, or hepatopancreas. The bioconcentration factors in descending order were crucian carp > E. nuttallii > Chinese mitten crab > sediments. These results demonstrate different absorption and enrichment in different environmental components and tissues in the same aquatic animal.
