Abstract (EN): Biosorption is a sustainable biological treatment for remediating environmental hazardous matrices. The shells of the invasive bivalve Corbiculafluminea were tested for their potential as a natural, abundant sorption material to cope with extremely toxic olive oil mill wastes (OOMW). Shells of C.fluminea were exposed for 14 days to OOMW and variations in the chemical composition of the waste and the shells were monitored by FTIR analysis. In general, the results showed the inefficacy of the shells in adsorbing chemicals from OOMW, namely regarding predominant aromatic structures. A significant slight increase in the 1750-1180 cm(-1) region was found, relating to a mild reduction of the peak areas in the same FTIR region noted in shells, which suggests partial shell dissolution; this trend was further supported by the parallel increase of the levels of both pH and Chemical Oxygen Demand. Although the shells of C.fluminea were found inadequate as a sink for the organic components present in OOMW, the abundance of the resource and previous evidence of its absorption capacity for different contaminants support the need for extended research on the use of this biomaterial as a sorption agent in bioremediation.
