In order to compare with and assess the metal-accumulating ability of the soldier crab (Mictyris brevidactylus), the concentrations of copper (Cu), zinc (Zn), nickel (Ni), lead (Pb) and cadmium of ambient water and the Pacific oyster (Crassostrea gigas) were investigated. Seawater, soldier crabs and Pacific oysters were simultaneously collected from the Changhua coastal area, located in West-Central Taiwan. The Pacific oyster and stream results proved that site B is contaminated by Cu, Zn and Pb from streams B-1 and B-2. The highest Cu, Zn, Ni and Pb concentrations in soldier crabs appeared at site B, and significant differences in the accumulated concentrations of Cu, Pb, Zn and Ni in soldier crabs were found between the sites tested. The highest bioconcentration factors of Cu, Zn, Ni and Pb in soldier crabs appeared at site B, indicating that the soldier crab can accumulate Cu, Zn and Pb to the same degree as the Pacific oyster. In fact, soldier crabs can accumulate more Ni than Pacific oysters, better reflecting the conditions of the ambient environment. These phenomena, as well as the fact that the soldier crab is able to accumulate relatively high levels of Cu, Zn, Pb and Ni, suggest that this crab is a potential biomonitor of Pb and Ni pollution in aquatic ecosystems.
为了比较和评估招潮蟹（短指和尚蟹）的金属积累能力，对环境水体以及太平洋牡蛎（长牡蛎）中的铜（Cu）、锌（Zn）、镍（Ni）、铅（Pb）和镉的浓度进行了调查。海水、招潮蟹和太平洋牡蛎均同时采自位于台湾中西部的彰化沿海地区。太平洋牡蛎和溪流的检测结果表明，B 点受到来自 B - 1和 B - 2溪流中铜、锌和铅的污染。招潮蟹体内铜、锌、镍和铅的最高浓度出现在 B 点，并且在所测试的不同点位之间，招潮蟹体内铜、铅、锌和镍的积累浓度存在显著差异。招潮蟹体内铜、锌、镍和铅的最高生物富集系数出现在 B 点，这表明招潮蟹积累铜、锌和铅的程度与太平洋牡蛎相同。事实上，招潮蟹积累镍的能力比太平洋牡蛎更强，能更好地反映周围环境状况。这些现象，以及招潮蟹能够积累相对高水平的铜、锌、铅和镍这一事实，表明这种螃蟹是水生生态系统中铅和镍污染的潜在生物监测指标。
