Abstract
Metals concentrations were studied in dominant seaweeds and their adjacent sediments in
Bandar Abbas and Bandar Lengeh tidal areas. The status of selected heavy metals (Ni, Cd, Pb,
Cu) was determined in sediments and 15 dominant seaweed species including 4 species of
Chlorophyta, 4 species of Phaeophyta and 7 species of Rhodophyta. Samples of seaweed and
sediment were collected seasonally during November 2007 to August 2008 from intertidal
regions of nine sites along the Bandar Abbas and Bandar Lengeh coasts. Powdered samples of
sediments and seaweed were digested and analyzed using Atomic Absorption
Spectrophotometer (A.A.S). Concentrations of Cu, Pb, Cd, and Ni were 5.24, 20.44, 5.40 and
33.83μg/g-1 dry wt. in sediments. Concentration of these metals in μg/g-1 dry weight in
Chlorophyta were 11.11, 25.79, 4.76 and 46.57, in Phaeophyta were 9.18, 17.68, 4.82 and
36.65, and in Rhadophyta were 9.80, 21.03, 4.96 and 50.43, respectively. The marine seaweed
species collected during all seasons and sites in Bandar Abbas and Bandar Lengeh were
identified as Entromorpha compressa and Padina pavonica, respectively.
