PHGs and ADIa derived for the present study.
| Metal intake guidelines | Al | Cd | Crb | Cu | Mnc | Ni | Pb |
|---|---|---|---|---|---|---|---|
| PHGd (μg/L) | 600 | 0.04 | 0.02 | 300 | 0.09 | 12 | 0.2 |
| NOAEL/LOAEL | 125 mg/day | 19 μg/day | 0.5/mg/kg-day | 426 μg/kg-day | NA | 1.12 mg/kg-day | 2.86 μg/day |
| UF | 100 | 50 | NA | 3 | NA | 1,000 | 3 |
| ADI (μg/day) | 1,250 | 0.38 | 0.1 | 7,100 | 1.8 | 56 | 0.95 |
| Abbreviations: ADI, acceptable daily intake; NA, not applicable; PHGs, public health goals; UF, uncertainty factor. aSee “Methods” for the calculation of ADI.b For PHG, Cr(VI) potency factor was used instead of NOAEL/LOAEL.cREL for manganese via inhalation was used instead of a PHG value (μg/m3).dAs reported in Cal/EPA PHG documents (Cal/EPA 2001a, 2001b, 2006, 2008a, 2008b, 2009, 2011b). | |||||||
