1080 Reassessment Application October 2006<br />

Appendix C<br />

Abstract: Chick embro heart fragments in primary hangingdrop culture were treated with sodium<br />

fluroacetate to induce inhibition <strong>of</strong> aconitate hydratase, a mitochondrial enzyme <strong>of</strong> the tricarboxylic acid<br />

cycle. The mitochondria were analyzed in the living myoblasts by phasecontrast timelapse<br />

cinemicrography. The results were recorded in 1 16 mm film. After 2030 minutes contact <strong>of</strong> the cells with<br />

the inhibitor some mitochondrion became thickened and swollen. The swelling was polymorphous,<br />

asynchronous and reversible; the name mitochondrion could swell and shrink many times. Some<br />

mitochondria seemed not to respond to fluroacetate and remained rodlike. Mitochondria appeared the only<br />

cell components to be morphologically affected by fluroacetate and the changes were specifically caused by<br />

the inhibitor. The type <strong>of</strong> mitochondrial swelling differed from the largeamplitude inspirationdependent<br />

swelling <strong>of</strong> the isolated mitochondria in vitro and from the configurational changes <strong>of</strong> isolated<br />

mitochondria associated with the respiratory states. The evidence pointed to specific connection between<br />

the biochemical lesion caused by fluroacetate and the configurational changes <strong>of</strong> the mitochondria. The<br />

mitochondrial swelling as to a large extent revered by washing the cultures with Tyrode physiological<br />

saline solution and the reversal was further accentuated by incubation <strong>of</strong> the cultures in fresh nutrient<br />

medium.<br />

Abstract: Poisoning <strong>of</strong> natural baits with 1080 powder dissolved in an adhesive is effective for killing deer<br />

in an area <strong>of</strong> high rainfall and dense vegetation, where conventional methods <strong>of</strong> control have met with<br />

limited success in in recent years. Experiments showed that natural baits treated with the adhesive were<br />

fairly readily accepted by deer.<br />

Hygiene 47, 426-430.<br />

Keywords: sodium fluoroacetate/fluoroacetate/1080/poisoning/rats/birds/<strong>poisons</strong>/efficacy<br />

Abstract: Sodium fluoroacetate (1080) has been tested in the field as a poison for Rattus norvegicus and R.<br />

rattus. Direct poisoning (without prebaiting) was used in thirteen tests on R. norvegicus. In eight <strong>of</strong> these<br />

tests censuses showed kills <strong>of</strong> at least 89%; in three tests the poison failed, and in two the results were<br />

equivocal. Of three similar tests against R. rattus two were successful and one was a failure. Six tests <strong>of</strong><br />

1080 after prebaiting gave five successes (including one against R. rattus) and one in which the estimated<br />

kill was about 82%. In five out <strong>of</strong> six tests populations <strong>of</strong> R. norvegicus which had survived baiting with<br />

1080 showed shyness (refusal) <strong>of</strong> the poison when it was given in a new bait base. The LD50 <strong>of</strong> 1080 for a<br />

strain <strong>of</strong> white rats was found to be 3.8 mg/kg (approx. range 2.8-5.2). A number <strong>of</strong> wild birds and some<br />

domestic aniamls were accidentally killed during the tests despite stringent precautions taken in laying the<br />

bait and in warning occupiers. It is concluded that (a) although 1080 is probably more effective in direct<br />

poisoning than other <strong>poisons</strong> used in the past, it does not give as consistent results as the standard <strong>poisons</strong><br />

do after prebaiting; (b) 1080 is too dangerous for general use.<br />

<strong>of</strong> fluoroacetate in plant extracts by 19 F NMR. Phytochemistry 26, 2293-2295.<br />

Keywords: NMR<br />

Abstract: Examination <strong>of</strong> extracts from seeds and foliage <strong>of</strong> several species known to contain fluoroacetate,<br />

using 19FNMR spectroscopu, has shown the presence <strong>of</strong> the characteristic FCH2-signal in most <strong>of</strong> them<br />

and enabled quantitative determiniation <strong>of</strong> their fluoroacetate contect. No other fluorine-containing plant<br />

metabolites were detected; fluoroacetate was not detected in the extracts <strong>of</strong> several non-toxic species. The<br />

limit <strong>of</strong> detection is estimated to be ca 4 Fg/g.<br />
