| contents | Induction of metallothioneins in Mullus barbatus as specific biomarker of metal contamination: a field study in the western Mediterranean J. Campillo J Benedicto C. Martínez-Gómez Ciencias de la Tierra biomarker heavy metals Mullus barbatus metallothioneins Mediterranean Sea Red mullet (Mullus barbatus, Linnaeus, 1758) is one of the fish species used as bioindicator in the Mediterranean PollutionMonitoring Programme (MEDPOL). This paper presents the results of a field study on the induction of hepatic metallothioneins(MT) in red mullet as specific biomarker of metal contamination. Specimens of M. barbatus were collected in six areas withdifferent degrees of anthropogenic activities along the Iberian Mediterranean coast. The environmental exposure to heavy metalsof the populations was determined through the analyses of surface sediments collected in each study area. The MT levelsobtained showed statistically significant differences between areas, but not between specimens of different sex. Furthermore, thehighest MT levels were found in the most polluted areas. Hepatic MT levels in red mullet reflect the metal contamination presentin surface sediments, especially for Cu, for which a significant linear regression was found. The MT levels are better correlatedwith Cu and Cd concentrations than with Zn and Hg concentrations. The MT values obtained in this study are the first to bereported for this species in the Iberian Mediterranean and they should help in the interpretation of MT levels and to establish MTbackground levels for M. barbatus in the western Mediterranean. 2005 artículo científico 0185-3880 https://www.redalyc.org/articulo.oa?id=48003113 en http://www.redalyc.org/revista.oa?id=480 Ciencias Marinas application/pdf Universidad Autónoma de Baja California Ciencias Marinas (México) Num.1B Vol.31 |
