Resumo: | The levels of vanadium, rubidium and potassium were determined in Octopus vulgaris caught during commercial fishing activities at three locations (Cascais, Santa Luzia and Viana do Castelo) in Portugal in autumn and spring. We determined the concentration of these elements in digestive gland, branchial heart, gills, mantle and arms in males and females. At least five males and five females were assessed for each season/location combination. Elemental concentrations were determined by Particle Induced X-ray Emission (PIXE). Vanadium was detectable only in digestive gland and branchial heart samples. Its concentration was not correlated with total weight, total length or mantle length. There were no differences in concentrations of V, Rb and K between sexes. There were significant differences in vanadium concentrations in branchial hearts in autumn between samples from Viana do Castelo and those from the other two sites. We found a significant positive relationship between the concentration of vanadium and those of potassium and rubidium in branchial hearts. Branchial hearts appear to play an important role in decontamination of V. |

Las concentraciones de estos elementos se determinaron en la glándula digestiva, corazón branquial, branquias, manto y en los brazos de machos y hembras en otoño y primavera. Al menos cinco machos y cinco hembras se muestrearon para cada combinación de temporada/localidad. Las concentraciones de estos elementos fueron determinadas por el método de Particle Induced X-ray Emission (PIXE). El vanadio fue solamente detectado en glándula digestiva y en los corazones branquiales y su concentración no tuvo correlación con el peso total, longitud total o longitud del manto. No se detectaron diferencias significativas en la concentración de V, Rb y K, entre machos y hembras aunque sí en las cantidades de vanadio acumulado en la glándula digestiva en otoño y primavera en muestras de Cascais y Santa-Luzia. En el caso del V en los corazones branquiales, se encontraron diferencias significativas en el otoño entre concentraciones en muestras de Viana do Castelo y las de las otras dos localidades. Se encontró una relación significativa positiva entre la concentración de vanadio y las de potasio y rubidio en los corazones branquiales. Concentraciones de Rb y K están correlacionadas en todos los tejidos excepto los musculares. Los corazones branquiales parecen jugar un papel importante en la descontaminación del V.Repositório AbertoSeixas, SóniaPierce, Graham2010-06-14T14:32:22Z20052005-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10400.2/1514engSeixas, Sónia; Graham J.
