Select a model or model description from the table below (ordered alphabetically),
and the corresponding processes on the diagram will be highlighted.
Notes
- Compound D: Benzene, Toluene, n-Hexane
- Metabolite: Combination of Phenol & Hydroquinone
- Mode of Action: Bone Marrow
- The combination of the three VOC’s produce the health effects of concern.
- Data gaps: No models for #3 VOC fugitive emissions from mixing vessel, #6 partitioning between vapor and particle phases (air conc.), #11 particle resuspension from surfaces (especially floors), #17 VOC from mainstream smoking (may be able to use something from review article on smoking release from website http://ehpnet1.niehs.nih.gov/docs/1999/Suppl-2/375-381ott/abstract.html)
- Dr. John Little and others at Virginia Tech in Blacksburg, VA have developed diffusion algorithms for VOCs that may be an improvement over existing models for diffusion-controlled release in process #1 and the reversible, diffusive sink effect for processes #6, #7, & #8. Papers describing these algorithms have recently been accepted in the journals "Indoor Air" and " Environmental Science & Technology". Dr. Little's e-mail address is jcl@vt.edu.
