AB The biological effects induced by the pollutants present in soils, together with the chemical and physical characterizations, are good indicators to provide a general overview of their quality. However, the existence ofstudies where the toxicity associated to soils contaminated with mixtures of pollutants applying both in vitro andin vivo models are scarce. In this work, three soils (namely, Soil 001, Soil 002 and Soil 013) polluted withdifferent concentrations of hydrocarbons and heavy metals were evaluated using different organisms representative of human (HepG2 human cell line) and environmental exposure (the yeast Saccharomyces cerevisiae, theGram-negative bacterium Pseudomonas putida and, for the in vivo evaluation, the annelid Enchytraeus crypticus). Invitro assays showed that the soluble fraction of the Soil 001, which presented the highest levels of heavy metals,represented a great impact in the viability of the HepG2 cells and S. cerevisiae, while organic extracts from Soils002 and 013 caused a slight decrease in the viability of HepG2 cells. In addition, in vivo experiments showed thatSoils 001 and 013 affected the survival and the reproduction of E. crypticus. Altogether, these results provide ageneral overview of the potential hazards associated to three specific contaminated sites in a variety of organisms, showing how different concentrations of similar pollutants affect them, and highlights the relevance oftesting both organic and soluble extracts when in vitro safety assays of soils are performed.
