Environmental tracer analysis

Strontium isotope biosphere domains of Britain

Research in the geochronology and tracers facility is focused mainly on the use of the heavy isotopes of strontium (Sr) and lead (Pb), in conjunction with oxygen (O) and sulphur (S), to study movement, migration and traceability. We undertake a mixture of projects types, including collaborative supervision of PhD projects, research-grant awards, steering-committee awards and commercial projects.

Isotope studies in biosphere traceability

Isotope variations can be used to trace migration and movement, provenance material and provide a geochemical 'fingerprint' for products.

  • Sr isotopes are used to limit the possible origins of flora and fauna though the food chain. The nature and origin of the soil supplies plants with distinctive isotope characteristics.
  • Pb isotopes provide a tracking mechanism for pollution in both modern and historic times.
  • S provides data on the proximity and use of marine resources.
  • O isotopes monitor climate, drinking water and human mediation of water.
  • Carbon (C) and nitrogen (N) provide data on the photosynthetic characteristics of ingested plants and food-chain hierarchy.
