Description
Concentrations of Cu, Cr, Cd, Zn, Mn, Co, Pb and Ni were determined in benthic algae of Bay of Ribeira, Angra dos Reis, SE Brazilian coast. The results showed that these elements are concentrate under different degrees depending on the algae species considered: Galaxaura marginata and Caulerpa racemosa presented the highest concentrations (ppm) for Cu (5,2), Cd (1,5), Mn (91,5), Co (6,2) and Ni (8,0) and Cr (7,9) and Pb (21,9) respectively. These algae are then suggested as potential monitor species for these metals in tropical coastal waters. The estimated bioaccumulation factors varied from 102 for Ni to 105 for Pb, falling within the range reported in the literature, with the exception of Cd, which was found to be two orders of magnitude greater.

As concentracoes de Cu, Cr, Cd, Zn, Mn, Co, Pb e Ni foram medidas em algas bentonicas da Baia da Ribeira, Angra dos Reis. Os resultados mostram que estes elementos sao concentrados em diferentes graus dependendo da especie de alga considerada. Galaxaura marginata e Caulerpa racemosa apresentam concentracoes (ppm) mais elevadas de Cu (5,2), Cd (1,5), Mn (91,5), Co (6,2), e Ni (8,0) e Cr (7,9) e Pb(21,9), respectivamente, sendo portanto sugeridas como monitores potenciais para estes metais em areas costeiras tropicais. Os fatores de bioacumulacao estimados variaram de 102 para Ni a 105 para Pb, estando dentro da faixa relatada na literatura, a excecao do Cd, que se apresentou duas ordens de grandeza mais elevado.
