In this study, the concentrations of trace elements (TEs) in caught from the East China Sea were determined. There were significant differences between TE concentrations in different body parts. Cu, Zn, and Cd were the most concentrated in the digestive glands and the concentrations of Cr and Co were highest in the gills. No significant differences in concentrations were shown between these tissues. In the four tissues analyzed, the mantle recorded the highest proportion of elemental load, while the digestive glands and gills had the lowest proportions. After maturity, TEs in the mantle showed no significant differences. In the digestive gland, the concentrations of all elements, except Zn, were significantly increased. The gonads illustrated apparent increases in the concentrations of Cr, Cu, and As. In the gills, the concentrations of Co and As were markedly increased.
在本研究中，测定了从中国东海捕获的[具体生物名称未给出]体内微量元素（TEs）的浓度。不同身体部位的TEs浓度存在显著差异。铜、锌和镉在消化腺中浓度最高，铬和钴在鳃中浓度最高。这些组织之间的浓度没有显著差异。在所分析的四个组织中，外套膜记录的元素负荷比例最高，而消化腺和鳃的比例最低。成熟后，外套膜中的TEs没有显著差异。在消化腺中，除锌外，所有元素的浓度均显著增加。性腺中铬、铜和砷的浓度明显增加。在鳃中，钴和砷的浓度显著增加。
