Dioxin Exposure Trends
Environmental Levels
- Peaked in late ’60s/early ’70s – decline since confirmed by sediment data
- Decline also supported by Emissions Inventory – shows significant decrease from ’87 to ‘;95 (~80%)
Human tissue data suggest current levels approximately half of 1980 levels
Steady State PK modeling of current intake levels project tissue levels will lead to 11 ppt TEQ lipid
