Breath Analysis for Chemical Exposure (304)
Problem: Need to rapidly and non-invasively determine the level of chemical exposure in humans and animals
Project Activity Scope (from Technical Overview Chart): Mechanisms through Instruments
PNNL Solution:
- Exhaled breath analysis based on ion trap mass spectroscopy and physiologically based pharmacokinetic modeling
- Field measurements can show toluene or benzene exposures as low as 1 ppb in humans
- Sensitive to exposures from aerosols, liquids and solids
Capabilities Employed to Meet Client Needs: Animal modeling; toxicology, electrochemical sensors; micro-fluidics; statistical data analysis, physiologically based pharmacokinetic (PBPK) modeling; ion trap mass spectroscopy.
