Palaemon elegans

Half-time persistence of zinc in the prawn (Palaemon elegans) is about 17 days (Nugegoda and Rainbow 1988b), and between 30 and 270 days for five other crustacean species (NAS 1979). Differences in half-time persistence are finked to differences in excretion rates of ionic zinc and complexed zinc. In general, ionic zinc in crustaceans is excreted first, then complexed zinc surface-adsorbed zinc is turned over faster than internally adsorbed zinc molting accounts for 33 to 50% loss of the total body burden in crabs (Eisler 1981).
