摘要

共心河是中国安徽省大山地区的主要河流之一,属于富硒高镉地区,但目前还没有研究重点关注鱼类体内硒和三卤甲烷的浓度、来源、拮抗作用和健康风险。本研究采集了 120 份鱼类样本(14 个品种)、24 份沉积物样本和 24 份水样,以调查典型的富硒高镉地区鱼类体内钛和硒的拮抗作用、来源和健康风险。恭新河鱼类体内锌和硒的含量高于背景值,这可能与不同鱼类的摄食习惯有关。探讨了 Se 与铜、铅、镉的明显拮抗作用,结果表明,Se/铜、Se/铅、Se/镉的比值分别有 30%、75%、100% 大于 1,表明鱼类体内的铜、铅、镉可能与 Se 结合或被 Se 解毒。元素来源分析表明,地质背景是鱼类样本中三卤甲烷和硒的来源。硒和三卤甲烷的含量都在中国的可接受水平准则之内,这表明食用鱼类不会对公民造成伤害。

Antagonistic Effects, Sources, and Distribution of Selenium and Toxic Metals in Fish from Selenium-Rich and High Cadmium Areas, Dashan Region, China.

The Gongxin River is one of the main rivers in the Dashan Region of Anhui Province in China, which is a Se-rich and high-Cd area, but no research has focused on the concentration, source, antagonism, and health risks of Se and TMs in fish. In this study, 120 fish samples (14 species), 24 sediment samples, and 24 water samples were collected to investigate the antagonistic effects, sources, and health risks of TMs and Se in fish from a typical selenium-rich and high cadmium region. Zn and Se in fish from the Gongxin River were higher than in the background, which might be attributed to the different feeding habits of different fish species. The apparent antagonism between Se and Cu, Pb, and Cd was explored, and the results showed that 30%, 75%, and 100% of the Se/Cu, Se/Pb, and Se/Cd ratios were greater than one, indicating that Cu, Pb, and Cd in fish might be combined with or detoxicated by Se. The source analysis of the elements showed that the geological background was the source of TMs and Se in fish samples. The amounts of Se and TMs were all within China's acceptable level guidelines, signifying no harm to citizens from eating fish.

期刊介绍: Biological Trace Element Research provides a much-needed central forum for the emergent, interdisciplinary field of research on the biological, environmental, and biomedical roles of trace elements. Rather than confine itself to biochemistry, the journal emphasizes the integrative aspects of trace metal research in all appropriate fields, publishing human and animal nutritional studies devoted to the fundamental chemistry and biochemistry at issue as well as to the elucidation of the relevant aspects of preventive medicine, epidemiology, clinical chemistry, agriculture, endocrinology, animal science, pharmacology, microbiology, toxicology, virology, marine biology, sensory physiology, developmental biology, and related fields.
