Abstract

Several shark species worldwide present high total arsenic (As) concentrations in muscle tissue, although to what extent has not yet been systematized. This study assessed total As concentrations in different shark species, as these animals comprise a significant fishery resource worldwide and are paramount for ecosystem equilibrium. A scientometric assessment retrieved 21 articles published between 1993 and 2023 reporting total As concentrations in muscle tissue of 27 shark species belonging to 16 different genera landed around the globe. Total As concentrations ranged from 0.14 to 152.20 mg kg⁻¹ wet weight and are not explained by mean length variability (23 to 297 cm). Toxic inorganic As contents usually range from 0.6 to 5%, in sharks, and organic, non-toxic, concentrations vary from 85 to 98% of total As contents, due to biologically-driven chemical speciation changes. Because of this, speciation assessments are paramount to adequately assess human health risks due to shark meat consumption.

全球有几种鲨鱼的肌肉组织中总砷 (As) 含量很高，但具体高到什么程度尚未系统化。本研究评估了不同鲨鱼物种的总砷浓度，因为这些动物是全球重要的渔业资源，对生态系统平衡至关重要。科学计量学评估检索了 1993 年至 2023 年间发表的 21 篇文章，这些文章报告了全球上岸的 16 个不同属的 27 种鲨鱼肌肉组织中的总砷浓度。总砷浓度范围从 0.14 到 152.20 毫克/千克-1（湿重）不等，且无法用平均长度变化（23 到 297 厘米）来解释。鲨鱼体内有毒的无机砷含量通常在 0.6%到 5%之间，而无毒的有机砷含量则占总砷含量的 85%到 98%，这是由于生物驱动的化学成分变化造成的。因此，要充分评估食用鲨鱼肉对人类健康造成的风险，就必须进行物种评估。

期刊介绍： Environmental Monitoring and Assessment emphasizes technical developments and data arising from environmental monitoring and assessment, the use of scientific principles in the design of monitoring systems at the local, regional and global scales, and the use of monitoring data in assessing the consequences of natural resource management actions and pollution risks to man and the environment.
