| Sumario: | In recent years, Peru has faced a significant increase in environmental liabilities related to hydrocarbons, which represents a serious problem for the environment (Bazán et al., 2024). This research evaluated the efficiency of the Californian red earthworm (Eisenia fetida) in the bioremediation of contaminated soils, comparing its ability to reduce contamination levels with the Environmental Quality Standards (ECA) established for soils. A 3x3 factorial experimental design was used, with three treatment levels and three repetitions, and the ANOVA test was applied for the statistical analysis of the results. The results revealed an efficiency in the bioremediation of soils contaminated by diesel. In the treatment with 10 worms, significant differences were found, highlighting treatment A3 (3.06 ml) as the most efficient. In contrast, for treatments with 20 and 30 worms, no significant differences were observed. The graphical analyzes indicate that the number of worms and the concentration of diesel influence the efficiency of the process, being more effective at moderate concentrations (A2) and less efficient at higher levels. In conclusion, the Californian red earthworm shows significant potential in the bioremediation of soils contaminated with hydrocarbons, being more efficient at lower concentrations (A1 and A2), while at higher concentrations (A3) a saturation is observed in its processing capacity. |
