The objective of this study is to investigate the levels, inter-species-specific, locational differences and seasonal variations of vanadium in sea cucumbers and to validate further several potential factors controlling the distribution of metals in sea cucumbers. Vanadium levels were evaluated in samples of edible sea cucumbers and were demonstrated exhibit differences in different seasons, species and sampling sites. High vanadium concentrations were measured in the sea cucumbers, and all of the vanadium detected was in an organic form. Mean vanadium concentrations were considerably higher in the blood (sea cucumber) than in the other studied tissues. The highest concentration of vanadium (2.56 μg g(-1)), as well as a higher degree of organic vanadium (85.5 %), was observed in the Holothuria scabra samples compared with all other samples. Vanadium levels in Apostichopus japonicus from Bohai Bay and Yellow Sea have marked seasonal variations. Average values of 1.09 μg g(-1) of total vanadium and 0.79 μg g(-1) of organic vanadium were obtained in various species of sea cucumbers. Significant positive correlations between vanadium in the seawater and V org in the sea cucumber (r = 81.67 %, p = 0.00), as well as between vanadium in the sediment and V org in the sea cucumber (r = 77.98 %, p = 0.00), were observed. Vanadium concentrations depend on the seasons (salinity, temperature), species, sampling sites and seawater environment (seawater, sediment). Given the adverse toxicological effects of inorganic vanadium and positive roles in controlling the development of diabetes in humans, a regular monitoring programme of vanadium content in edible sea cucumbers can be recommended.
本研究的目的是调查海参中钒的含量、种间差异、位置差异和季节变化，并进一步验证控制海参中金属分布的几个潜在因素。对食用海参样本中的钒含量进行了评估，结果表明不同季节、物种和采样地点存在差异。在海参中检测到高浓度的钒，且所有检测到的钒均以有机形式存在。海参血液中的钒平均浓度明显高于其他研究组织。与所有其他样本相比，糙海参样本中的钒浓度最高（2.56 μg g(-1)），有机钒含量也更高（85.5%）。渤海湾和黄海的刺参钒含量有明显的季节变化。各种海参的总钒平均值为1.09 μg g(-1)，有机钒平均值为0.79 μg g(-1)。观察到海水中的钒与海参中的有机钒之间存在显著正相关（r = 81.67%，p = 0.00），沉积物中的钒与海参中的有机钒之间也存在显著正相关（r = 77.98%，p = 0.00）。钒浓度取决于季节（盐度、温度）、物种、采样地点和海水环境（海水、沉积物）。鉴于无机钒的不良毒理学影响以及其在控制人类糖尿病发展中的积极作用，建议对食用海参中的钒含量进行定期监测。
