The application of SEM-EDX proved that the metal ions were sorbed on the surface of both tested algae.

The total mobilized fraction of a PAH compound was defined as a sum of that dissolved in the fluid and that sorbed on the residue.

It was found that 8-38% of the mobilized OCPs were sorbed on the residue and remained in the solid phase after the separation.

It was demonstrated that 10-41% of the spiked deuterated PAHs were sorbed on the assimilated residue, which would remain in the solid phase after separation.
