Artigo IPEN-doc 20722 Passive biomonitoring study and effect biomarker in oysters Crassostrea brasiliana (Lamark, 1819: Mollusca, Bivalvia) in Santos and Cananéia Estuaries in São Paulo State, Brazil2015 - CATHARINO, M.G.M.; VASCONCELLOS, M.B.A.; KIRSCHBAUM, A.A.; GASPARO, M.R.; SOUSA, E.C.P.M. de; MINEI, C.C.; MOREIRA, E.G.This study assessed the exposure and effects of trace elements in sentinel organisms, using the bivalve Crassostrea brasiliana in two estuarine areas in Sa˜o Paulo State, Brazil: Santos Estuary and Canane´ia Estuary, site of oyster farms, which was used as reference site. Oysters were evaluated for bioaccumulation of As, Co, Cr, Fe, Se and Zn by INAA and Cd, Pb and Hg by AAS. Effect biomarker was assessed by evaluation of lysosomal membrane stability. In the study of bioaccumulation of trace elements it was verified that Santos Channel presented the largest concentrations of elements studied in most cases. From the study of the cellular biomarker, it was verified that Santos Channel and winter showed higher stress to organisms in the present study.Artigo IPEN-doc 13732 Biomonitoring of Hg, Cd,Pb and other elements in coastal regions of Sao Paulo State, Brazil, using the transplanted mussel Perna perna (Linnaeus, 1758)2008 - CATHARINO, M.G.M.; VASCONCELLOS, M.B.A.; SOUSA, E.C.P.M. de; MOREIRA, E.G.; PEREIRA, C.D.S.Artigo IPEN-doc 13751 Avaliacao da contaminacao por elementos metalicos dos sedimentos do estuario Santos - Sao Vicente2008 - HORTELLANI, MARCOS A.; SARKIS, JORGE E.S.; ABESSA, DENIS M.S.; SOUSA, EDUINETTY C.P.M.Artigo IPEN-doc 17880 Biomonitoring of coastal regions of São Paulo state, Brazil, using mussels Perna perna2012 - CATHARINO, M.G.M.; VASCONCELLOS, M.B.A.; KIRSCHBAUM, A.A.; GASPARRO, M.R.; MINEI, C.C.; SOUSA, E.C.P.M. de; SEO, D.; MOREIRA, E.G.Artigo IPEN-doc 18063 Vanadium biomonitoring by using Perna perna (Linnaeus, 1758) mussels transplanted in the coast of the State os São Paulo, Brazil2012 - SEO, D.; VASCONCELLOS, M.B.A.; SAIKI, M.; CATHARINO, M.G.M.; MOREIRA, E.G.; SOUSA, E.C.P.M. de; PEREIRA, C.D.S.Artigo IPEN-doc 18757 Vanadium determination in Perna perna mussels (Linnaeus, 1758: Mollusca, Bivalvia) by instrumental neutron activation analysis using the passive biomonitoring in the Santos coast, Brazil2013 - SEO, D.; VASCONCELLOS, M.B.A.; CATHARINO, M.G.M.; MOREIRA, E.G.; SOUSA, E.C.P.M. de; SAIKI, M.Vanadium determination present in seawater is of great importance to evaluate marine contamination from industrial sources as well as to identify health hazards since mussels and other marine organisms are used as food. Besides, this evaluation in the Santos coast, SP, Brazil, is important, since this area is impacted by industrial and urban activities and discharges from ships and boats. In a previous study, V results obtained for transplanted mussel (active biomonitoring) were presented. This study aimed the V determination by passive biomonitoring by analyzing Perna perna mussels collected in natural environment, from three sites in Sa˜o Paulo State coast: Cocanha Beach (reference site), Ponta de Itaipu and Palmas Island. Ninety individuals of mussels were collected in each site between September/08 and July/09 during the four seasons of the year. After shell removal and sample preparation, V was determined by instrumental neutron activation analysis. For analytical quality control, the NIST Standard Reference Material SRM 1566b Oyster Tissue was analyzed and the results presented good accuracy. The V concentrations in mussels on dry mass basis varied from 0.77 ± 0.02 to 3.56 ± 0.88 mg kg-1 . Statistical tests were applied to the results showing differences on V concentrations among the sampling sites and season of sample collection.
