| Trace metal concentrations (Cd, Cu, Fe, Zn) and total-calcium content were measured in the gills of 2 marine fish (painted comber Serranus cabrilla and striped mullet Mullus barbatus) sampled in different stations in the cove of Cortiou, where the outlet collecting the waste waters of Marseille, France, is situated (NW Mediterranean). In parallel, the activity rates of some phase I enzymes (ethoxyresorufin-0-dealkylase, EROD; pentoxyresorufin-0-dealkylase, PROD) and phase II enzymes (glutathione-S-transferase, GST) were determined in the livers of both species of fish. Cadmium and copper concentrations were highly variable for both species. Two sampling stations situated in the dispersion area of waste waters seemed affected by chemical pollution. At these... |
