Environmental Metabolomics

Definition

Environmental metabolomics is the study of metabolites present in environmental samples, allowing researchers to analyze how living organisms interact with their environment at a metabolic level. This approach can uncover the influence of environmental factors on biological systems, helping to identify biomarkers of exposure to pollutants and understanding ecosystem responses to changes in their surroundings.
