Resumen : | The water-soluble-fractions (WSF) from biodiesel and biodiesel/diesel blends were compared to diesel in their sub-lethal toxicity to microalgae. Chemical analyses of aromatics, non-aromatics hydrocarbons and methanol were carried out in the WSF, the former showing positive correlation with increasing diesel concentrations (B100 < B5 < B3 < B2 < D). Biodiesel interacted with the aqueous matrix, generating methanol, which showed lower toxicity than the diesel contaminants in blends. The WSF caused 50% culture growth inhibition (IC50-96 h) at concentrations varying from 2.3 to 85.6%, depending on the tested fuels and species. However, the same species sensitivity trend (S. costatum > N. oculata > T.chuii > P. subcapitata) was observed for all the tested fuels. |
