- The bioavailability of field-aged Cd and Cu was calculated, and compared to the total
concentrations determined by acid digestion. Only 0.60–4.15% for Cd and 0.59–9.43%
for Cu were found to be bioavailable when determined by stomach-phase extraction.
The incorporation of bioavailability reduced more than 90% of the calculated risk of the
metals at the site of study. It should be noted that such a reduction may not be
generalized and the site-specific bioavailability needs to be determined case by case.
