- •
Bauxite residues were investigated as mineral amendments for dredge marine sediment stabilization.
- •
Application of 5% bauxite residue to dredged sediment is a sustainable approach to limit leaching of cationic pollutants.
- •
Leachates toxicity towards rotifers (Brachionus plicatilis) was high after 48 h of contact.
- •
Improvements are needed to limit leaching of anionic pollutants and to lower toxicity of the leachates.
