Table 2.
Estimated weekly intake of metals (μg kg−1 b.w. and %TWI or %BMDL) based on geometric mean concentration in different age and socio-economic groups.
| Weekly intake | Age group (years) | Socio-economic status group | ||||
|---|---|---|---|---|---|---|
| 18–40 | 41–60 | ≥ 61 | Low | Medium | High | |
| Cd (μg kg−1 b.w.) | 0.199 | 0.106 | 0.389 | 0.274 | 0.166 | 0.214 |
| Cd (%TWI) | 7.95 | 4.23 | 15.6 | 11.0 | 6.65 | 8.55 |
| Hg (μg kg−1 b.w.) | 0.142 | 0.075 | 0.277 | 0.196 | 0.119 | 0.152 |
| Hg (%TWI) | 10.9 | 5.80 | 21.3 | 15.0 | 9.12 | 11.7 |
| Pb (μg kg−1 b.w.) | 0.055 | 0.029 | 0.108 | 0.076 | 0.046 | 0.059 |
| Pb (%BMDL01) | 3.68 | 1.96 | 7.20 | 5.08 | 3.08 | 3.96 |
| Pb (%BMDL10) | 8.76 | 4.67 | 17.1 | 12.1 | 7.33 | 9.43 |
TWI tolerable weekly intake, BMDL01 benchmark dose lower confidence limit (for cardiovascular Pb effects), BMDL10 benchmark dose lower confidence limit (for chronic kidney Pb effects).
