Key Findings of the Reassessment Exposure Document (con.)
General Population exposure – animal fats in commercial food supply
- Local sources make little contribution to most people’s exposure
- Environmental levels in meat & dairy productions are major contributor
Air deposition onto plants consumed by domestic meat and dairy animals – primary route for contamination of commercial food supply
Reservoir sources – significant component of current exposure; may dominate future exposures
- Accounts for most coplanar PCB exposures
- Unknown contribution for PCDDs/PCDFs
Special populations may be more exposed, but prevalence is not well substantiated
