The status of Óbidos Lagoon (Portugal) was assessed combining water quality, sediment quality, and oxidative stress responses in female shore crab Carcinus maenas. Two sites were surveyed in October 2005, one located in an impacted, confined inner branch (Barrosa) and another in the middle of the la...

Se evaluó el estado de la Laguna de Óbidos (Portugal) mediante la calidad del agua y del sedimento, así como las respuestas al estrés oxidativo en hembras de cangrejo Carcinus maenas. En octubre de 2005 se muestrearon dos estaciones en la laguna, una localizada en un brazo interno e impactado (brazo Barrosa) y otra en la parte media de la laguna, con mayor influencia de aportes oceánicos. Las concentraciones de amonio y nitrato + nitrito fueron notablemente mayores en Barrosa, mientras que las diferencias en los niveles de metales en el sedimento fueron mínimas. La disponibilidad de Mn, Cu, Ni y Cd disueltos fue mayor en Barrosa, especialmente por la mañana, lo que sugiere la influencia de procesos internos que ocurren cerca del sedimento durante la noche. Las hembras de C. maenas capturadas en Barrosa presentaron alteraciones en sus antioxidantes hepatopancreáticos, una clara indicación de que el brazo interno es una zona más contaminada. Los cangrejos mostraron un incremento en la actividad glutatión peroxidasa, catalasa y glutatión S-transferasa, así como daño peroxidativo de lípidos, mientras que para el glutatión total no se observaron diferencias. Las respuestas significativas no fueron acompañadas por un incremento significativo de los niveles de metales en el hepatopáncreas, lo que indica que los efectos adversos pudieron haber sido causados por el sinergismo de las fuentes de estrés. |
