Relative contributions to uptake are ranked similarly to these intake contributions. However, because inhaled aluminium is approximately seven times more bioavailable than aluminium in drinking water, the contribution of inhaled aluminium to uptake (1.7 × 10 -5 mg/kg b.w./day) exceeds the corresponding contribution from drinking water (6.9 × 10 -6 mg/kg b.w./day).
