Resumen
Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) The Todos os Santos bay (TSB) is the second largest Brazilian bay. Despite the large number of potential anthropogenic sources of mercury (Hg) in the bay, data on this element in this marine environment are very scarce. Total Hg concentrations were therefore determined in sediment, macroalgae, and seagrass species collected during dry and rainy seasons, from eight locations. In similar to 45 % of the sediment samples, Hg concentration was two to four times higher than the upper value considered the regional Hg background (15 mu g kg(-1)). Geoaccumulation index indicated that Hg contamination was at none to heavily contaminated. In Padina sp., Caulerpa sp., Hypnea sp., and Halodule wrigthii, Hg concentrations ranged from 10.61-297.61, 15.59-74.50, 12.84-158.03, and 4.02-67.25 mu g kg(-1), respectively. 23 19 19686 19695 Fundacao de Amparo a Pesquisa do Estado da Bahia (FAPESB) Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP) [2010/19040-4] Conselho National de Desenvolvimento Cientifico e Tecnologico (CNPq) Coordenacao de Aperfeicoamento de Pessoal de Nivel Superior (CAPES) Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)
