Chemical Fingerprinting in the Environment (20)

Chemical Sensing Macro-Property Measurements Atmospheric Modeling

Problem: Determine if the origin of chemicals found at field sites can be traced to specific chemical sources/processes

Project Activity Scope (from Technical Overview Chart): Interaction mechanisms through Measurement & Analysis System Applications

PNNL Solution:

  • Evaluated chemicals present at site
  • Used chemical database to estimate chemical stability & reactions at site
  • Analyzed co-present chemicals to project back-in-time to identify & estimate source contributions
  • Successfully performed analysis at several waste sites

Capabilities Employed to Meet Client Needs: Atmospheric dispersion modeling; oil spill modeling; chemical and biological agent database developments; probability analysis; accident and consequence analysis; fate and transport modeling applications; waterborne pathway determinations; source-term contributions; population exposure modeling; mass balance and biotransformation effects analysis.
