Elemental concentrations in different species of seaweeds from Loreto Bay, Baja California Sur, Mexico: implications for the Geochemical control of metals in algal tissue

摘要

Concentration levels of 21 elements were analyzed by instrumental neutron activation analysis (Rb, cs, Ca, Sr, Ba, Sc, Cr, Fe, Co, Ni, Zn, Se, As, Sb, Th, U, Br, Hf, Ta, Zr, and Ag) in seven different seaweed species (Codium cuneatum, Sargassum sinicola, Padina durvillaei, Laurencia johnstonii, L. Papillosa, Gracilaria pachidermatica and Hypnea pannosa), collected in a shallow coastal Zone from Bahia de Loreto, Baja California Sur, Mexico.
