| Abstract: | Levels of cadmium, copper, aluminium, iron, manganese and zinc (Cd, Cu, Al, Fe, Mn and Zn) in deep-sea sediments and sediment-feeding
holothurians are reported. Profiles of metals were found to vary with depth in the sediment. Holothurian foregut metal values
are generally closer to surficial sediment levels, whereas body wall levels, with the exception of Cd and Cu, were generally
lower. Holothurians are presented as potential biomonitors of metal concentrations in the deep-sea floor environment.
