Experimental intoxications were performed on the Crayfish Pontastacus leptodactylus using hydrosoluble uranium nitrate. Investigations demonstrate that Crustacea are able to concentrate both uranium main radioactive isotopes 238U and 235U within the cuticle, gill epithelium, midgut gland (= hepatopancreas) and macrophagic hemocytes. The storage occurs within nucleus and lysosomal system where uranium is precipitated in the form of an unsoluble phosphate. The proposed hypothesis for the metal extrusion is the following: residual bodies containing the uranium precipitates are extruded into the extracellular space where they are absorbed, by phagocytosis, by the macrophagic hemocytes.
使用水溶性硝酸铀对小龙虾窄指螯虾进行了实验性中毒研究。研究表明，甲壳纲动物能够在角质层、鳃上皮、中肠腺（=肝胰腺）和巨噬血细胞中富集铀的两种主要放射性同位素238U和235U。储存发生在细胞核和溶酶体系统内，铀以不溶性磷酸盐的形式沉淀。关于金属排出的提出的假说是：含有铀沉淀物的残余体被排出到细胞外空间，在那里它们被巨噬血细胞通过吞噬作用吸收。
