Abstract

A mathematical equation is presented for the calculation of a safe reentry time into an orange orchard which has been treated with a pesticide chemical, the residues of which produce a dose—dependent response in humans. The equation relates the kinetics of the rate of loss of pesticide residues, which remain on the foliage of pesticide—treated trees, and the kinetics of the rate of change in a measurable physiological response (blood cholinesterase activity), brought about by exposure of humans to the decreasing residue levels, to the time of reentry of workers into the orchard.
