Total methylmercury (MeHg) uptake models predicting blood and hair mercury (Hg). Total MeHg uptake (μg/month) from all seafood for subjects with measures of blood and/or hair Hg was calculated using three different corrections: assuming 100% bioavailability (model #1); accounting for seafood-specific bioaccessibility (model #2); accounting for seafood-specific bioavailability (model #3). All βs (SD in brackets) and r2 s were significant (p<0.001).
| Hg Biomarker | Model | Β (SD) | r2 | |
|---|---|---|---|---|
| Blood | #1 | Assuming 100% bioavailability | 0.21(0.02) | 0.20 |
| #2 | Accounting for bioaccessibility | 0.24(0.02) | 0.21 | |
| #3 | Accounting for bioavailability | 0.24(0.02) | 0.21 | |
| Hair | #1 | Assuming 100% bioavailability | 0.36(0.03) | 0.36 |
| #2 | Accounting for bioaccessibility | 0.37(0.03) | 0.37 | |
| #3 | Accounting bioavailability | 0.37(0.03) | 0.37 |
