The rate of percutaneous absorption of parathion has been estimated in vivo by following the disappearance from a topical deposit of 32P-labelled material in the cat. There was a definite tendency towards inhibition of plasma cholinesterase activity in two cats, while a third animal failed to show this. The amount of radioactivity in the blood five hours after the application corresponded to 0.02 to 0.04 micrograms parathion per ml. It was concluded that parathion is very slowly absorbed, which makes this compound very unsuitable as a model substance in studies of the process of percutaneous absorption. The results have been discussed with special regard to experimental errors involved and to practical implications.
