Abstract：
:The effects of metals (cadmium, zinc, copper and nickel in a mixture) on biosorption and biodegradation of five mixed polycyclic aromatic hydrocarbons (PAHs), namely fluorene (FLU), phenanthrene (PHE), fluoranthrene (FLA), pyrene (PYR) and benzo[a]pyrene (BAP), by Selenastrum capricornutum were investigated. Exposure to metals significantly influenced the interactions between cells and PAHs and, such impact was PAH species dependent. For low molecular weight PAHs (FLU and PHE), both metal dosage and exposure time posed a significant, positive effect on their removal, with up to 99% of FLU and 89% of PHE were removed from the medium in seven days, which was mainly due to the cellular degradation induced by metal stress. For high molecular weight PAHs (FLA, PYR and BAP), the presence of metals did not affect the removal efficiency, but the uptake in the ethyl acetate-extractable fraction of the biomass was increased.
