Seventeen species of green, brown and red seaweeds collected fromManora, Buleji and Paradise Point near Karachi coast of Pakistan wereanalyzed for their elemental composition with the help of Perkin Elmer 3 100Atomic Absorption Spectrometer. Several significant elements e.g., Ca, Cd, Co,Cr, Cu, Fe, K, Mg, Na, Pb and Zn were detected quantitatively. Ca, Fe, K, Mgand Na were found in large amounts (223.79-13129.56 ppm), Cr, Cu, Pb and Znwere present in small quantities (1.27-10.49 ppm), while Cd and Co weredetected in extremely small amounts (0.39-1.10 ppm). The average quantity ofNa was found to be the highest among these algae (13129.56 ppm), followed byK (11655.71 ppm) and Ca (4242.17 ppm) with low quantity of Cr (1.27 ppm), Co(1.10 ppm) and Cd (0.39 ppm).
