1080 Reassessment Application October 2006<br />

Appendix C<br />

improved GLC method using pentafluorobenzyl derivatisation and electroncapture detection was proposed<br />

recently (Okuno and Meeker 1980) but the presence <strong>of</strong> interfering peaks and low, variable recovering were<br />

a problem.<br />

The preparation <strong>of</strong> fluorescent derivatives <strong>of</strong> monocarboxylic acids using<br />

4bromomethyl7methoxycoumarin (BrMmc) and their separation by high performance liquid<br />

chromatography (HPLC) has recently been reported (Lam and Grushka 1978). We have adapted this<br />

method to the analysis <strong>of</strong> sodium fluoroacetate. A simple but efficient method for recovering this<br />

compound from baits is also described.<br />

Abstract: Compound 1080 ® is a man-made sodium salt <strong>of</strong> fluoroacetic acid or fluoroacetate, which occurs<br />

in nature as the toxin in many species <strong>of</strong> poisonous plants. The toxicity <strong>of</strong> such plants had long been<br />

recognized, but the toxic agent was not identified as fluoroacetate until 1944. By that time, the pesticidal<br />

potential <strong>of</strong> synthesized sodium fluoroacetate (code number 1080-44) was being explored in the United<br />

States in a war time, crash program aimed at finding new rodenticides. Compound 1080, the main product<br />

<strong>of</strong> that program, proved to be the best rodenticide known up to that time. It was found to be even more<br />

toxic to canids than to rodents, so was used experimentally for coyote control beginning in November 1944.<br />

Compound 1080 was authorized for operational use in governmental predator control in 1946. Large meat<br />

baits, or bait stations, injected with 1080 solution and placed on livestock ranges in winter quickly became<br />

a preferred method for reducing coyote populations that preyed on sheep and cattle. The use <strong>of</strong> 1080 bait<br />

stations peaked in Fiscal Year (FY) 1963, when over 16,000 stations were placed by the U. S. Fish and<br />

Wildlife Service (FWS) Predator and Rodent <strong>Control</strong> (PARC) program. After 1963, numbers <strong>of</strong> 1080<br />

stations declined year by year to 1972 when the use <strong>of</strong> 1080 and other predacides on Federal lands and in<br />

Federal programs was stopped by President Nixon's Executive Order 11643, followed by Environmental<br />

Protection Agency (EPA) suspension and cancellation <strong>of</strong> registrations for 1080 and other predacides. The<br />

1080 cancellation was based partly on high potential hazard to humans, even though no human had ever<br />

been killed or seriously injured in connection with the use <strong>of</strong> this toxicant in coyote control.<br />

Paradoxically, most <strong>of</strong> the political agitation over Compound 1080 focused its use in predator control even<br />

though much greater amounts were used for rodent control. The total amount <strong>of</strong> 1080 sold in the U. S.<br />

during 1968-72, the last five years in which 1080 bait stations were used, was approximately 10,003 lb.<br />

Only 1.3 percent (129 lb) <strong>of</strong> that amount was used for predator control. The largest amount <strong>of</strong> 1080 used<br />

for coyote control in the United States in any one year was about 42.4 lb, in FY 1963.<br />
