NOTES

The chemical concentration and area of skin exposed varied according to the specific acitivity of the chemical that was applied. The % absorption was calculated from the amount excreted in the urine, corrected for incomplete excretion by comparison with excretion from a iv dose. I have extrapolated back the amount found in the urine from the data given in the paper/
