Lobsters, Homarus americanus , were exposed in a flow‐through system to a sublethal concentration of zinc (Zn ++ ) for 4 d and then transferred to flowing unspiked sea water for 7 d. The concentrations (μg/g dry weight) of Zn ++ after the four days of exposure were in the order gill > green gland > haemolymph > hepatopancreas > crusher tissue > crusher muscle > pincer tissue > shell > testes > heart > pincer muscle > abdominal (tail) muscle. After 7 d in unspiked water the concentration of Zn ++ in each of the tissues decreased, but did not return to pre‐exposure levels. In terms of the total tissue burden the level of Zn ++ in only the hepatopancreas continued to increase during the depuration phase. The data were analysed using a four‐compartment model with haemolymph as the “central” compartment. The exchange of Zn ++ between gills and water was rapid, between gills and haemolymph was somewhat slower, and between haemolymph and tail muscle was extremely slow.
