A sensitivity analysis using alternative toxic equivalency factors to estimate U.S. dietary exposures to dioxin-like compounds.

Highlights: [•] Novel sensitivity analyses of alternative toxic equivalency factors (TEFs). [•] Characterized uncertainty in dioxin toxic equivalency (TEQ) intakes. [•] Estimated U.S. mean daily TEQ intake of 23pg/day from 8 food categories. [•] Dairy (other than milk), beef, and seafood contribute most to TEQ intake. [•] TEF probability distributions needed to conduct probabilistic uncertainty analyses. [ABSTRACT FROM AUTHOR]
