The concentrations of ten trace metals were determined in the gills, muscles, hepatopancreas, and exoskeleton tissues of Xenograpsus testudinatus that lives around shallow and acidic hydrothermal vents off Kueishan Island, northeastern Taiwan. The analytical results demonstrate that the metal concentrations vary significantly with the type of crab tissue. The concentrations of Al, Cd, Co, Cu, Fe, Ni, and Zn are highest in the gills, whereas the concentration of Mn is highest in the exoskeleton. Cr and Pb concentrations are similar across the different tissues. The enhanced accumulation of most metals in the gills suggests the metal accumulation via the respiration pathway rather than the uptake of food. The results also reveal that the distribution patterns of metals in tissues are similar in the hepatopancreas and muscles, but very different in both the gills and the exoskeleton, perhaps because of the different pathways of metal utilization in the different crab tissues.
在台湾东北部龟山岛附近浅酸性热液喷口周围生活的 Xeno grapsus testudinatus 的鳃、肌肉、肝胰腺和外骨骼组织中，测定了十种痕量金属的浓度。分析结果表明，金属浓度随蟹组织类型的不同而有显著差异。Al、Cd、Co、Cu、Fe、Ni 和 Zn 的浓度在鳃中最高，而 Mn 的浓度在外骨骼中最高。Cr 和 Pb 的浓度在不同组织中相似。大多数金属在鳃中的积累增加表明金属通过呼吸途径而不是通过摄取食物积累。结果还表明，金属在组织中的分布模式在肝胰腺和肌肉中相似，但在鳃和外骨骼中则非常不同，这可能是由于不同蟹组织中金属利用的途径不同。
