- •
Mining wastes of the former Pb–Zn mining district of Touiref (Tunisia) is a source of contamination.
- •
The Sidi Bou Said Stream at the site is a pathway for contaminant transport.
- •
Enrichment factor values revealed in sediments of the two cores have extremely severe enrichment from Cd, Pb, and Zn.
- •
Contaminants exceed guideline values in sediment.
- •
Chemical extraction data indicates a higher potential mobility and bioavailability of Cd and Pb.
