Résumé :
|
Antioxydant systems were studied in the freshwater bivalve Uniotumidus transplanted from a control site to four different contaminated areas, in order to study the biological response according to the contamination characteristics.The response of the gills and the digestive gland was not always paralleled, which can be explained by differences in the bioavailability of pollutants. In some cases, a relationship was not found between the antioxydant response and the degree and the type of contamination in sediments, suggesting that the effects could result from nonidentifeid pollutants or/and be indicators of bioavailability
