The marine phanerogam Posidonia oceanica (L.) Delile was collected from a presumably unpolluted “reference” area in Port Cros National Park, Mediterranean Sea, in November 1985, and its elemental composition was studied by gamma spectrometry after neutron activation and by atomic-absorption spectrophotometry. Neutron-activation analysis revealed 23 elements and atomic-absorption spectrophotometry 4 others. Including all known records by other investigators, this brings the total of elementary components identified in P. oceanica up to 42: antimony, arsenic, barium, bromine, cadmium, cesium, calcium, carbon, cerium, chromium, cobalt, copper, europium, gold, hafnium, hydrogen, iodine, iron, lanthanum, lead, magnesium, manganese, mercury, molybdenum, nickel, nitrogen, phosphorus, potassium, rubidium, samarium, scandium, selenium, silver, sodium, strontium, tantalum, terbium, thorium, uranium, ytterbium, zinc, zirconium. These elements display significant differences in their distribution in the various parts of the plant (roots, rhizomes, and growing and freshly budded leaves).
