Concentrations of Hg and other metals such as Ag, Cr, Co and Ni in soft tissues and byssi of the blue mussel (Mytilus edulis) from three sites along the east coast of Kyushu Island, Japan, were determined by a cold-vapor technique. Large inter-regional differences in metal concentrations in both soft tissues and byssi were observed. The tissue concentrations of Hg were significantly greater in M. edulis from the most contaminated locations (Saganoseki) compared to those from a non-industrialized area (Urashiro). It is evident that, compared to the soft tissue, byssus is a more sensitive biomonitor for Hg, Cr, Co and Ni. From the data obtained in the present study evidently results that the soft tissue and especially byssi of M. edulis appear to be good bioindicators for identification of coastal areas exposed to Hg contaminants.
采用冷蒸气技术测定了日本九州岛东海岸三个地点的蓝贻贝（紫贻贝）软组织和足丝中汞及银、铬、钴和镍等其他金属的浓度。在软组织和足丝中的金属浓度均观察到较大的区域间差异。与来自非工业化地区（浦代）的紫贻贝相比，来自污染最严重地点（佐贺关）的紫贻贝组织中汞的浓度显著更高。显然，与软组织相比，足丝对汞、铬、钴和镍是更敏感的生物监测指标。根据本研究获得的数据明显可以得出，紫贻贝的软组织尤其是足丝似乎是识别受汞污染物影响的沿海地区的良好生物指示物。
