In the late 1980s, all use of sodium fluoroacetate as a rodenticide was discontinued. Fluoroacetate and metabolites are defluorinated in the liver and rapidly excreted by the renal route within a few days in sublethal exposure. He tried to talk but was unable to articulate. The parents did not know whether he drank any of the solution. review of the chemical sodium fluoroacetate, commonly known as 1080. reregistration eligibility review and decisions on the pesticide chemical sodium fluoroacetate. (2011) Sodium Fluoroacetate. Sodium fluoroacetate (compound 1080), fluoroacetamide (compound 1081), and methyl fluoroacetate have been used to poison a number of herbivorous and predatory animal species. The statistical parameters of this model are good, R2Train = 0.87 and R2Test = 0.89 (see Table 17). Other identifiers . Coyotes usually attack the throat of their prey; in doing so, they puncture the collar and ingest a sufficient amount of the toxicant to be lethal. Table 16. Accidental consumption of poisoned livestock or wildlife is unlikely to pose any risks to human beings. A further fragment likely related to excess toxicity is para-trifluoro-aminobenzenes. The above-mentioned fragments are also capable to avoid seven false positives. The plasma t½ is 3.6–6.9 h in goats, 6.6–13.3 h in sheep, 1.1 h in rabbits, and 1.6–1.7 h in mice (Eason et al., 1993; Gooneratne et al., 1995). A typical fatal case involved a 40-year-old man who was found unconscious in his bedroom. In response, some native Australian herbivores have evolved considerable fluoroacetate resistance, allowing baiting regimens that target several introduced animal species which had previously caused the endangerment of certain native species. He gradually became comatose during gastric lavage, and consciousness was never regained. Ernest Hodgson, in Pesticide Biotransformation and Disposition, 2012. Each collar, constructed to surround the neck of a goat or lamb, has within it two sealed pouches that together contain a small quantity (300 mg) of the “Restricted Use Pesticide,” compound 1080 (sodium fluoroacetate), formulated in a liquid carrier. On admission, the boy was comatose and exhibiting carpopedal spasms, tetanic convulsive movements, irregular respiration, and great cardiac irregularity. Many insect species with public health importance have long been known to be resistant to one or more pesticides (Brown and Pal, 1971; Georghiou and Saito, 1983) and a much larger number of agricultural pests are also resistant. They are unlikely to be effective unless given before any neurological signs develop. There was no striking change until 14 h after admission, when ventricular asystole occurred. Any serious but reversible interference with respiration or general circulation is liable to produce some cases in which the patient survives but with severe brain damage. Reexamination 1 year later showed that the boy had had no further neurological trouble, and his mental and physical development has proceeded normally (Gajdusek and Luther, 1950). We found two false positives in this case: hexadecadienol acetate (ID 145) and Z-11-hexadecenal (ID 2). Samples of choice include blood, skeletal and/or muscle tissue, rumen contents, and vomit. Sodium fluoroacetate occurs naturally as an anti-herbivore metabolite in various plants but can also be produced synthetically. High levels of citrate bind to serum calcium, leading to hypocalcemia that may result in heart failure, and also inhibit phosphofructokinase that is an important glycolytic enzyme. Serious illness followed by full recovery occurred in a 2-year-old boy who was found licking crystals from the screw cap of a bottle of sodium fluoroacetate solution. The actions of fluoroacetate have also been described in animals having ingested the poison leaf Gifblaar (Dichapetalum cymosum). Their use is severely restricted because of the extreme toxicity of these compounds to man and most animals. He was brought to hospital about 6 h later because he began to have generalized convulsive movements and became stuporous. The cardiac arrhythmias characteristic of poisoning by sodium fluoroacetate are likely to produce such interference. Sodium fluoroacetate is also mentioned in the 1994 non-fiction book "Midnight in the Garden of Good and Evil" by John Berendt. Sodium fluoroacetate (compound 1080), fluoroacetamide (compound 1081), and methyl fluoroacetate have been used to poison a number of herbivorous and predatory animal species. Sodium fluoroacetate 95% Synonym: Fluoroacetic acid sodium salt, Gifblaar poison CAS Number 62-74-8. The resulting solutions contain moderate concentrations of hydroxide ions and have pH's greater than 7.0. An example of outliers with this fragment is Propachlor (ID 216). The acute renal failure was reversible. Those individuals utilizing them must go through an approved training program and be specially certified to use this device. During the decade 1971–1981, 111 cases of accidental or unintentional poisoning with sodium fluoroacetate were collected by the National Poison Center of Israel. Thus many instances are known in which species or strains differ in their susceptibility to pesticides, the resistance arising through selection in the field. Tolerance also may exist in situations in which it has been impossible to demonstrate any increased ability to metabolize the toxicant; finally, there are instances of tolerance for which the mechanism is not only unknown but unexplored. In many instances it has been possible to define the genetic mechanisms responsible for observed differences in the metabolism of the pesticides in question. There are several fragments, which are probably related to an enhanced or anyway unusual reactivity in the molecule not identified by the modelling tools, or because their occurrence is low, or because the fragment is more complicated than those used within the QSAR models. The chemical formula is CH2FCOONa. While the first characteristic of the outliers, the interference with electron transport, is based on the mechanism of action, and therefore not predictable a priori from the structure, the other characteristics are based on the chemistry of the compounds and become rules to identify the weaker region of the applicability domain of the model. Sodium fluoroacetate, or "1080" as it was called during the investigation period, is said to be one of the most noxious substances known, since it is toxic to all mammals, man included. Sodium fluoroacetate baits are stable in cool, dry conditions, including partially mummified carcasses of target species, but are biodegraded when moisture and ambient temperature are sufficient. Ventricular fibrillation is the cause of death, and some horses may be found dead with no outward signs of struggle.87,103, Ramesh C. Gupta, James W. Crissman, in Haschek and Rousseaux's Handbook of Toxicologic Pathology (Third Edition), 2013. Beilstein/REAXYS Number 3915223 . Birds have survived up to 10 days after dosing with sodium fluoroacetate, and reptiles have survived up to 22 days. He was brought to hospital about 6 h later because he began to have generalized convulsive movements and became stuporous. All cases had signs of transient cardiac dysfunction, but in addition acute renal failure was seen in three of the five patients, two of them with frank uremia. In spite of treatment with phenobarbital, three additional seizures occurred during the next 12 h. There was no further illness, and the patient was discharged 4 days later. Chemical structure of sodium fluoroacetate (NaFC. Terminal convulsions also may occur. Another fatal case was remarkable for its combination of prolonged survival following the ingestion of an almost certainly very large dose. We identified two cases: a benzylic hydrogen linked to oxygen, which is part of an oxime group, Ar–CH–O–N =. Statistical parameters of the hybrid model for trout toxicity within the applicability domain (factor of 50). A ‘toxic collar’ was developed which contains a very small amount of sodium fluoroacetate (0.3 mg per collar). We found a positive outlier with this condition: ethylene dichloride (ID 115). Sodium fluoroacetate is known under its brand name "1080". Secondary poisoning in carnivores is always a risk, even when used deep in rat burrows, as the intended victims generally come out to die. MDL number MFCD00002682 Naturally occurring fluoroacetate can be found in Gastrolobium minus (family: Fabaceae), a flowering plant in Western Australia and often referred to as the ‘poison pea.’ Descriptions of the fluoroacetate activity may have been described as early at 1904 in Sierra Leone, when colonists used extracts of Chailletia toxicaria to poison rats. Ventricular ectopic beats preceded the ventricular arrhythmia, which was then followed by ventricular tachycardia and fibrillation. However, the regulations were not always followed. Convulsions should be controlled with diazepam and/or pentobarbitone. 607-169-00-5 . Sheep receiving sodium fluoroacetate (0.1 mg/kg) contained the residue in plasma, kidney, heart, muscle, spleen, and liver as 0.098, 0.057, 0.052, 0.042, 0.026, and 0.021, respectively (Eason et al., 1993). This collar could be placed around the throats of livestock and would contain chemical pouches that would be ruptured when the animal was attacked by a predator thus restricting the poison only to the predator. Disorientation, agitation, bruxism, apparent blindness, weakness, ataxia, and coma have been reported in sheep. There has been a great deal of unfortunate scaremongering about risk to human beings, when in fact the risk is remote. In all these examples, an ECG is essential (Oliver and Somerville, 1968). An example involved an 8-year-old boy who was in status epilepticus when he entered hospital. Chung (1984) reported on five cases collected between 1975 and 1981 in Taiwan. The livestock protection (LP) collar, more commonly referred to as a toxic collar, is a relatively new device used to selectively kill livestock-depredating coyotes. A further fragment with a likely role in excess toxicity with activated hydrogen is the group CH–NO2. NC, number of compounds; ND, number of descriptors; K, slope; q, intercept. To have a better overview of the chemical typical groups involved, we list below again the fragments already introduced related to the highest error (factor 50) (see also Table 16).
