Abstract

Introduction The aims of the study were to determine the distribution of As, Hg, and Se in the muscle and liver of the dolphinfish Coryphaena hippurus and the striped marlín Kajikia audax and to assess the health risks related to the intake of their edible portion. Methods Fish were captured during sport fishing trips in Cabo San Lucas, Mexico (southern Gulf of California) in 2018 and 2019. Elemental analyses were conducted using atomic absorption spectrophotometry. Results and Discussion For both fish species, Spearman’s correlations of the elemental concentrations with the length and weight of individuals were positive and significant, except for Se in the muscle of C. hippurus with size of specimens. The median concentrations (in micrograms per gram wet weight) of Hg, As, and Se were as follows: in C. hippurus were 0.08, 0.81, and 0.20 in the muscle and 0.09, 2.40, and 0.27 in the liver, respectively, and in K. audax were 0.29, 0.591, and 0.27 in the muscle and 0.12, 1.50, and 0.23 in the liver, respectively. In C. hippurus , the sequence of elemental concentrations was As > Se > Hg in both the muscle and liver; in K. audax , the order resulted as As > Hg > Se in the muscle and As > Se > Hg in the liver. For both fish species, the hazard quotients (assuming that 10% of As was inorganic and considering total Hg as a surrogate for methylmercury) related with their consumption were HQ Hg > HQ Se >HQ As . With respect to the hazard index, in C. hippurus , all values were below 1; in K. audax , the values were above 1 in 82.8% of children, 45.3% of women of childbearing age, and 32.8% of men. Under the HBV Se approach, the values were positive for all tissues in both species, indicating that Se is present in molar excess over Hg. From these estimations, it is necessary to continue monitoring and dietary risk assessment, particularly in people with elevated rates of fish consumption and those in vulnerable groups.

来自加利福尼亚湾南部的鲯鳅和条纹马林鱼中汞、砷和硒的健康风险评估

本研究的目的是确定As、Hg和Se在海豚（Coryphaena hippurus）和斑纹marlín海豚（Kajikia audax）肌肉和肝脏中的分布，并评估摄入其可食用部分所带来的健康风险。方法于2018年和2019年在墨西哥卡波圣卢卡斯（加利福尼亚湾南部）的运动钓鱼旅行中捕获鱼类。元素分析采用原子吸收分光光度法。结果与讨论除了棘鱼肌肉中的硒含量与标本大小呈显著正相关外，两种鱼类的硒含量均与个体长度和体重呈显著正相关。汞、砷和硒的中位数浓度（单位为微克/克湿重）分别为：马尾鱼肌肉为0.08、0.81、0.20，肝脏为0.09、2.40、0.27；乌达克斯鱼肌肉为0.29、0.591、0.27，肝脏为0.12、1.50、0.23。在棘草中，元素浓度顺序为As &；gt；Se和gt;肌肉和肝脏中的汞含量；在K. audax中，顺序为as &；gt；Hg, gt;肌肉中的硒和As &；gt；Se和gt;肝脏中的汞。对于这两种鱼类，与它们的消费相关的危害商数（假设10%的砷是无机的，并考虑总汞作为甲基汞的替代品）是HQ Hg & & gt；总部Se &；gt；总部As。在危害指数方面，沙棘的危害指数均小于1；82.8%的儿童、45.3%的育龄妇女和32.8%的男性的值大于1。在HBV Se方法下，这两个物种的所有组织的值都是阳性的，表明硒的摩尔含量超过汞。根据这些估计，有必要继续监测和饮食风险评估，特别是在鱼类消费量增加的人群和弱势群体中。

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.
