Abstract

Fish are important food sources for humans, and the availability of appropriate amount of trace elements (TEs) plays a crucial role in fish growth. Currently, due to large volumes of sewage discharge, high levels of certain elements are present in aquatic environments, and these elements accumulate in fish and potentially affect human health. In this study, the distribution and bioaccumulation capacity of trace elements in six dominant fish species from Chaohu Lake (China) were analyzed. The results showed that the bioaccumulation capacity of fish for Zn was greater than other TEs. And the source of the TEs in the fish were explored along with the concentration of the TEs in the aquatic environment, which indicated that TEs in fish were mainly obtained through ingestion and indirectly affected by the industrial activities in the basin. Additionally, stable carbon and nitrogen isotopes were used to classify the trophic levels and explore the biological magnification of TEs of the fish. It was found that Sb and Sr showed biomagnification with the increase of trophic level of fish. Based on the above analyses, the environmental biogeochemical cycle model of TEs in the lake was distinguished and established, which can offer valuable insights for sustainable fishery management in the downstream Yangtze River Delta ecosystem.

中国典型浅流湖流域鱼类体内微量元素的分布、生物累积、营养传递和风险评估
鱼类是人类的重要食物来源,而适量的微量元素(TEs)对鱼类的生长起着至关重要的作用。目前,由于大量污水排放,水生环境中某些元素含量较高,这些元素在鱼类体内蓄积,可能影响人类健康。本研究分析了巢湖六种主要鱼类体内微量元素的分布和生物累积能力。结果表明,鱼类对锌的生物累积能力大于其他微量元素。鱼类体内微量元素的来源与水生环境中微量元素的浓度同时得到探究,表明鱼类体内的微量元素主要通过摄食获得,并间接受到流域内工业活动的影响。此外,还利用稳定碳和氮同位素对鱼类的营养级进行了分类,并探讨了鱼类 TEs 的生物放大作用。结果发现,随着鱼类营养级的提高,锑和锶出现了生物放大现象。基于上述分析,区分并建立了湖泊中 TEs 的环境生物地球化学循环模型,为长江三角洲下游生态系统的可持续渔业管理提供了有价值的启示。

期刊介绍: Frontiers of Environmental Science & Engineering (FESE) is an international journal for researchers interested in a wide range of environmental disciplines. The journal''s aim is to advance and disseminate knowledge in all main branches of environmental science & engineering. The journal emphasizes papers in developing fields, as well as papers showing the interaction between environmental disciplines and other disciplines. FESE is a bi-monthly journal. Its peer-reviewed contents consist of a broad blend of reviews, research papers, policy analyses, short communications, and opinions. Nonscheduled “special issue” and "hot topic", including a review article followed by a couple of related research articles, are organized to publish novel contributions and breaking results on all aspects of environmental field.
