The environmental risk of metal mixtures will be assessed using a unicellular alga. The work aims to:
1) quantify the dynamic metal speciation of single metals and metal mixtures in presence of small ligands.
2) study the bioaccumulation of the single metals and the metal mixtures in the presence of the ligands using the alga: evaluation of the rate limiting step on the uptake.
3) characterize the water samples collected on the Tagus estuary (Portugal).
