摘要

重金属污染是海洋生态系统的一个重要问题，构成了严重的威胁。监测海鱼体内的重金属含量对保障人类健康至关重要。本研究专门研究了南海琼州海峡海鱼体内砷（As）、镉（Cd）、铬（Cr）、铜（Cu）、镍（Ni）、铅（Pb）、硒（Se）和锌（Zn）八种元素的生物积累。Zn为优势重金属，平均浓度为39.5 μg/g。大多数海鱼的重金属摄取量风险较低，其中银鲳的风险最低，为10-6。此外，由于其As生物积累风险较高，建议谨慎食用，其水平达到70.1 μg/g，对总目标危害商的贡献显著，为94.3%（3.64）。本研究为沿海环境保护和生态事件的预防提供了有价值的建议。

Heavy metal alarm of marine fish consumption surrounding Qiongzhou Strait, the South China Sea

Heavy metal pollution presents a significant concern in marine ecosystems, posing a serious threat. Monitoring the levels of heavy metals in marine fish is crucial for safeguarding human health. This study specifically investigates the bioaccumulation of eight elements (arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), nickel (Ni), lead (Pb), selenium (Se), and zinc (Zn)) in marine fish in the Qiongzhou Strait in the South China Sea. Zn emerged as the predominant heavy metal, with an average concentration of 39.5 μg/g. Most marine fish showed a low risk of heavy metal intake, Pampus argenteus exhibited the lowest risk at 10–6. Moreover, caution is advised regarding the consumption of Uroconger lepturus due to its elevated risk of As bioaccumulation, with levels reaching 70.1 μg/g, contributing significantly to the total target hazard quotient at 94.3% (3.64). This study provides valuable recommendations for coastal environmental protection and the prevention of ecological incidents.

期刊介绍： Frontiers in Marine Science publishes rigorously peer-reviewed research that advances our understanding of all aspects of the environment, biology, ecosystem functioning and human interactions with the oceans. Field Chief Editor Carlos M. Duarte at King Abdullah University of Science and Technology Thuwal is supported by an outstanding Editorial Board of international researchers. This multidisciplinary open-access journal is at the forefront of disseminating and communicating scientific knowledge and impactful discoveries to researchers, academics, policy makers and the public worldwide. With the human population predicted to reach 9 billion people by 2050, it is clear that traditional land resources will not suffice to meet the demand for food or energy, required to support high-quality livelihoods. As a result, the oceans are emerging as a source of untapped assets, with new innovative industries, such as aquaculture, marine biotechnology, marine energy and deep-sea mining growing rapidly under a new era characterized by rapid growth of a blue, ocean-based economy. The sustainability of the blue economy is closely dependent on our knowledge about how to mitigate the impacts of the multiple pressures on the ocean ecosystem associated with the increased scale and diversification of industry operations in the ocean and global human pressures on the environment. Therefore, Frontiers in Marine Science particularly welcomes the communication of research outcomes addressing ocean-based solutions for the emerging challenges, including improved forecasting and observational capacities, understanding biodiversity and ecosystem problems, locally and globally, effective management strategies to maintain ocean health, and an improved capacity to sustainably derive resources from the oceans.
