Even though seaweeds have been considered a nutrient-rich dietary source of minerals in other parts of the world, there is little knowledge about trace element accu-mulation in seaweeds of the Arabian Gulf. The Arabian Gulf is of particular interest due to being an extreme environment, as it features some of the highest temperatures and salinities observed in any marine waters in the world. This study determined the minerals contents using inductively-coupled plasma-mass spectrometry (ICP-MS) in 10 of the most com-mon seaweeds of this region (Iyengaria stellata, Padinaboergesenii, Chondriasp., Feldmannia indica, Codium papil-latum,Sargassum aquifolium,Ulva chaugulii,Ulva tepidaandUlvasp.) supported by morphological and molecular (DNAbarcode)-based identification. The finding ofU. chauguliire-ported here is a new record for Kuwait. Most of the seaweeds were rich in essential minerals including Ca, Mg, Na, K, Feand Zn and their contents were higher than those of other mineral-rich foods. Principal component analysis revealed specific distributions of minerals in seaweeds.U. tepidaandI.stellatawere found to be exceptionally rich inmost of the macro- and trace elements along with low As and Se,and thus can be utilized for food and feed applications.
