Table 4.
Dioxin-like chemical concentration and summary TEQ (mean (95% confidence interval) and range) comparisons between ACHS II and estimated NHANES 2014 (imputed from NHANES 2003/04 using half-life estimates of Milbrath et al., 2009).
| Dioxin-like Chemicals (pg/g lipid) | ACHS II (2014) 26–87 years old (n=338) |
Estimated NHANES (2014) 31–96 years old (n=1546) |
