Antioxidant enzyme activities in periphyton as new biomarkers of low metal pollution in streams

Utilisation des activitées enzymatiques anti-oxydantes comme biomarqueurs de contaminations métalliques faibles en cours d'eau

Résumé

The goal of this study was to assess the use of antioxidant enzyme activities (AEA) in periphyton communities as biomarkers of low metal pollution under multiple stress field conditions. With this purpose, the effects of metal exposure were investigated in situ in a low order stream, located in a former mining area. Translocation experiments were performed along a gradient of metal pollution including a control and five polluted sites. Physical and chemical parameters, metal bioaccumulation, AEA and diatom species composition in periphyton were followed over the five weeks of translocation. Dissolved Zn concentration was
