Contaminant Biology: Stable Isotope Applications
Project Manager:Craig Stricker
Environmental contaminants of natural and anthropogenic origin represent a major stressor to ecosystems, including human and wildlife populations. A better mechanistic understanding of contaminant cycling under natural environmental conditions is necessary to mitigate and protect our natural resources. Stable isotope techniques are extremely useful in resolving trophic pathways by which contaminants become bioavailable, bioaccumulate, and biomagnify. The objectives of this project are to:
- Utilize stable isotopes to better resolve the geochemical cycling of contaminants that influences bioavailability.
- Use stable isotope data to constrain contaminant sources.
Employ stable isotope techniques to infer trophic transfer pathways of select contaminants.
