Metabolomic-Based Assessment of Earthworm (Eisenia fetida) Exposure to Different Petroleum Fractions in Soils.

ABSTRACT: Background/Objectives: Petroleum contamination in soil exerts toxic effects on earthworms (Eisenia fetida) through non-polar narcotic mechanisms. However, the specific toxicities of individual petroleum components remain insufficiently understood. Methods: This study investigates the effects of four petroleum components-saturated hydrocarbons, aromatic hydrocarbons, resins, and asphaltenes-on earthworms in artificially contaminated soil, utilizing a combination of biochemical biomarker analysis and metabolomics to uncover the underlying molecular mechanisms. Results: The results revealed that aromatic hydrocarbons are the most toxic fraction, with EC50 concentrations significantly lower than those of other petroleum fractions. All tested fractions triggered nota
