摘要:
为了探究水产品的种类和养殖时间对养殖水体及水产品中土臭素（GSM）和二甲基异莰醇（2-MIB）的影响，本研究以无锡地区不同种类水产品和养殖水体为研究对象，在5-10月份对养殖水体中GSM和2-MIB的质量浓度以及收获时水产品中GSM和2-MIB的含量进行检测。结果表明，水产品种类和养殖时间的变化会在一定程度上影响养殖水体中GSM和2-MIB的质量浓度，在不同水产品的养殖水体中，GSM、2-MIB质量浓度随养殖时间推移呈现出不同的变化趋势。在水产品中仅检出GSM，其在虾蟹类、四大家鱼和罗非鱼中的含量分别为0.45 μg/kg、0.62 μg/kg和0.94 μg/kg，生物浓缩系数分别为40.10、71.68、27.07，四大家鱼富集GSM能力最强，说明水产品的种类会影响水产品中GSM的含量。
Abstract:
Some aquatic species and aquaculture water were collected in Wuxi to research the interaction between odor chemicals and aquaculture species. The levels of geosmin (GSM) and 2-methylisoborneol (2-MIB) in the samples were quantitatively analyzed. The results showed that the variety of aquatic products and the change of aquaculture time would affect the mass concentrations of GSM and 2-MIB in aquaculture water to some extent. In the aquaculture water with different aquatic species, the mass concentrations of GSM and 2-MIB showed different trends over time. Only GSM was detected in aquatic products, the contents in shrimps and crabs, four major Chinese carps and tilapia were 0.45 μg/kg, 0.62 μg/kg and 0.94 μg/kg, respectively. The four major Chinese carps had the strongest ability to enrich GSM, with the bioconcentration factors (BCF) of 71.68. This ability of shrimps and crabs (40.10) was next to it, and the tilapia (27.07) was the weakest. Aquatic species can affect GSM content in aquatic products.
