Notes
- Compound B: Ethylene Glycol
- Metabolite: methoxyacetic acid
- Mode of Action: Kidney
- Data gap: No models for #5 partitioning between vapor and particle phase or #10 particle resuspension from surfaces (especially floors)
- Data gap: No PBPK or PBPD model for ethylene glycol in the newborn or child, current available information is insufficient to develop a PBPK or PBPD model for this age group
- 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.
