Correlations were run using data from individual animals. To reduce the number of data points on this graph, only the mean Pb concentration and dose from each group were plotted.

Correlations were run using data from individual animals. To reduce the number of data points on this graph, only the mean Pb concentration and dose from each group were plotted.

Correlations between relative response (RR) or bioavailability (RBA) of Pb as determined by blood, kidney, liver, and bone dose–response curves and the bioavailability factor (BAFs) as determined from soil samples by the stomach phase of the physiologically based extraction test (PBET).
