Identify contamination sources, understand propagation processes, and target remediation. Stable metal isotopes provide a level of discrimination unattainable by conventional methods.
In multi-source environments, elemental concentrations alone cannot discriminate between inputs. Stable isotopes differentiate pollutant sources, quantify their respective contributions, and identify those with the most critical impact on populations or the environment.
This approach is particularly effective in urban, industrial, and mining areas, where it pinpoints specific contamination sources, whether legacy or still active, to guide more targeted, cost-effective remediation.
Beyond source identification, stable metal isotopes reveal the biogeochemical mechanisms at work in contaminated environments: mineral adsorption, redox reactions, and transfers between dissolved and particulate phases.
By quantifying the isotopic fractionation associated with each process, we reconstruct contaminant pathways from emission to accumulation, enabling anticipation of their fate and proper sizing of remediation actions.
Stable isotopes are valuable tools for studying the fate of emerging contaminants in the environment: novel metallic compounds, nanoparticles, and industrial residues whose dynamics remain poorly understood.
We support research teams and environmental consultancies in designing tailored sampling campaigns, selecting the relevant isotopic systems, and interpreting the resulting signatures, in coordination with partner analytical platforms.
Eight metallic tracers available through our partner platforms, covering the main environmental contaminants.
From sampling campaign design to data interpretation, we support you at every stage.
