Parameter values of the model based on fits to the data of Woollen et al. (1992) on both average and individual urinary excretion time courses of trans-DCCA, cis-DCCA and 3-PBA following an oral and dermal exposure in volunteers.

aThe reported mean parameter values are the values giving the best fit (÷2) to average experimental time course data of Woollen et al. (1992) (n = 6).bThe range of parameter values reported correspond to the minimum and the maximum parameter values giving the best fit (χ2) to average and individual experimental data of Woollen et al. (1992) from 4 volunteers. Individual parameter values for two volunteers were not selected because of the presence of incomplete voids.
