Abstract

Background

The nutritional compositions of abalones (Haliotis discus hannai) vary with geographical origins and environmental factors. Traceability is an important part of food safety, and the heavy metals in the aquatic environment pose a threat to living organisms. Therefore, we present a comparative analysis of the nutrient and heavy metal content in abalones from three different sea areas in China: the Bohai Sea, East China Sea, and South China Sea. This study uniquely addresses the correlation between nutrient composition and heavy metal accumulation. By employing weighted gene co-expression network analysis, we reveal the biological implications of heavy metal exposure, specifically focusing on chromium, copper (Cu), manganese, zinc, arsenic (As), cadmium, and lead.

Results

Betaine, glycine, and glycogen appeared in three comparisons. The abalone in the East China Sea had the highest content of betaine, and the abalone in the South China Sea had the highest contents of glycine and glycogen. Among the measured metals, the heavy metals accumulated in the viscera were significantly higher than that in the muscle, except Cu, and As showed a high target hazard quotient and carcinogenic risk.

Conclusion

Betaine, glycine, and glycogen might be important indicators for origin traceability of abalone. Abalones from the South China Sea provide higher nutritional value. Cu had different accumulation patterns and As showed high health risks, and heavy metals brought oxidative stress to abalone. Our findings not only contribute to the understanding of abalone safety and quality but also provide a novel approach to assessing impact of heavy metals on marine food sources. © 2025 Society of Chemical Industry.

中国不同海域大盘盘鱼营养特征及重金属积累的健康风险

背景：鲍鱼（Haliotis discus hannai）的营养成分因地理来源和环境因素而异。可追溯性是食品安全的重要组成部分，水生环境中的重金属对生物构成威胁。为此，本文对中国渤海、东海和南海三个不同海域的鲍鱼的营养成分和重金属含量进行了比较分析。这项研究独特地解决了营养成分与重金属积累之间的关系。通过加权基因共表达网络分析，我们揭示了重金属暴露的生物学意义，特别是铬，铜（Cu），锰，锌，砷（As），镉和铅。结果：三组比较均出现甜菜碱、甘氨酸和糖原。甜菜碱含量最高的是东海鲍鱼，甘氨酸和糖原含量最高的是南海鲍鱼。所测重金属中，除Cu和As表现出较高的靶害商和致癌风险外，其余重金属在脏器内的蓄积量均显著高于肌肉。结论：甜菜碱、甘氨酸和糖原可作为鲍鱼原产地溯源的重要指标。来自南海的鲍鱼营养价值更高。铜具有不同的积累模式，砷具有较高的健康风险，重金属给鲍鱼带来氧化应激。我们的研究结果不仅有助于理解鲍鱼的安全和质量，而且为评估重金属对海洋食物来源的影响提供了一种新的方法。©2025化学工业协会。

期刊介绍： The Journal of the Science of Food and Agriculture publishes peer-reviewed original research, reviews, mini-reviews, perspectives and spotlights in these areas, with particular emphasis on interdisciplinary studies at the agriculture/ food interface. Published for SCI by John Wiley & Sons Ltd. SCI (Society of Chemical Industry) is a unique international forum where science meets business on independent, impartial ground. Anyone can join and current Members include consumers, business people, environmentalists, industrialists, farmers, and researchers. The Society offers a chance to share information between sectors as diverse as food and agriculture, pharmaceuticals, biotechnology, materials, chemicals, environmental science and safety. As well as organising educational events, SCI awards a number of prestigious honours and scholarships each year, publishes peer-reviewed journals, and provides Members with news from their sectors in the respected magazine, Chemistry & Industry . Originally established in London in 1881 and in New York in 1894, SCI is a registered charity with Members in over 70 countries.
