Absorption of sodium monofluoroacetate (“1080”) solution by carrot baits

Abstract

The absorption of sodium monofluoroacetate (“1080”) by carrot baits of various thicknesses has been studied. Whole carrots, peeled or unpeeled, or carrots chopped into cubes or slices of different thicknesses were immersed in solutions containing 1/2 lb, 1 lb, and 2 lb of “1080” in 6 gal of water for varying lengths of time (5 sec, 1 min, and 5 min). Absorption of “1080” was decreased by the skin of the carrot. Although there was some absorption through the intact skin, the amount of poison absorbed by peeled whole carrots was 58% to 138% greater than for similarly treated unpeeled carrots. The trial confirmed that “1080” was absorbed into the body of the carrot. For chopped carrot the “1080” content of the baits was almost inversely proportion to the thickness. Time of immersion did not have a very marked effect on absorption.
