Abstract
Samples of four different species of seaweed were collected monthly between October 2000 and March 2001 from the coast of the Strait of Magellan Chile to establish baseline levels of trace metals silver total mercury nickel lead antimony vanadium and zinc and to compare the accumulation capacity among species The algae included in the study were Adenocystis utricularis n = 15 Enteromorpha sp n = 11 Mazzaella laminarioides n = 12 and Porphyra columbina n = 6 The concentration range of each metal in μg g−1 dry weight varied as follows Ag = ND03 Hg = ND002 Ni = ND126 Pb = ND112 Sb = ND197 V = ND1134 and Zn = 141079 Results showed that levels of Ag Hg Ni Pb Sb V and Zn for all species were similar to those found in other studies for noncontaminated areas with very little influence from anthropogenic activity Also among the four species studied macroalgae Enteromorpha sp had the highest capacity for metal accumulation and could therefore be considered as a biomonitor for future studies in the area
