Abstract The concentrations of Na, Mg, Al, S, Cl, K, Ca, Sc, Ti, V, Mn, Fe, Co, Ni, Zn, As, Se Br, Rb, Sr, Mo, Ag, Sb, I, Cs, Ba, La, Sm, Tb, Yb, Hf, Ta, Th and U in some types of marine macrophytes (algae and seagrass), collected from 7 stations along the Mediterranean Sea coast of Egypt were determined using instrumental neutron activation analysis. The contents of elements in marine macrophytes indicated that they accumulated elements at different levels depending on their type of species (brown, red, green and seagrass) and the ambient water conditions. In general, the levels of classically investigated elements, particularly, Mn, Fe, Co, and Ni determined in the macrophytes in the present study are lower or within the wide range of values previously reported for the Mediterranean Sea. While the concentrations of Zn measured in some samples showed a higher trend reflecting a possible source of Zn contamination |
