The common marine mussel Mytilus edulis collected from French coastal waters of the Channel, Atlantic Ocean and Mediterranean Sea was shown to contain lanthanum; higher levels were found in the samples collected from the Eastern Channel and more particularly from the Baie de Seine. 139La+ was detected within lysosomes of digestive gland, labial palp and gill epithelium, macrophage hemocytes and chitinous tissue. Lanthanum was always associated with high phosphorus contents in the lysosomes. Thus, lanthanum which exists in sea water at trace level is taken up by the Mussel, via gill and digestive tractus, in a soluble form and then concentrated in the form of an insoluble phosphate in the storage organelles. A comparison is made between the behaviour of lanthanides and actinides in the biological systems.
从法国英吉利海峡、大西洋和地中海沿海水域采集的常见贻贝紫贻贝被证明含有镧；在从东英吉利海峡特别是从塞纳湾采集的样本中发现镧的含量更高。在消化腺、唇瓣和鳃上皮、巨噬血细胞和几丁质组织的溶酶体中检测到了¹³⁹La⁺。镧在溶酶体中总是与高磷含量相关。因此，海水中痕量存在的镧通过鳃和消化道以可溶形式被贻贝吸收，然后以不溶性磷酸盐的形式在储存细胞器中浓缩。对镧系元素和锕系元素在生物系统中的行为进行了比较。
