摘　　要：The demand for simple and rapid bioassays in ecotoxicological evaluations is of paramount importance in order to speed up environmental monitoring programs.In this study we performed bioassays with lettuce seeds and two species of terrestrial isopods (Armadillidium vulgare and Porcellio dilatatus) for the ecotoxicological assessment of a landfarming soil from a petrochemical complex area.The solubilized content of test soil demonstrated a concentration-response type toxic effect on seed germination rate,and a delay on germination,but showed toxic effect on seedlings wet weight only at the highest concentration.Toxic effects were also observed in mortality rate and avoidance behavior of the two woodlice species.These results demonstrated the sensitiveness of the organisms studied,and highlighted the possibility to use these bioassays in environmental monitoring programs in areas contaminated with fossil fuels.The demand for simple and rapid bioassays in ecotoxicological evaluations is of paramount importance in order to speed up environmental monitoring programs.
