Famphur is to be applied as soon as possible after heel fly activity ceases. Not to be usd on lactating dairy cows or dry dairy cows within 21 days of freshening calves less than 3 months old, animals stressed from castration over-excitement or dehorning, sick or convalescent animals. Animals may be dehydrated and under stress following shipment. Do not treat Brahman bulls.Famphur is a cholinesterase inhibitor. Do not use this product in animals with exposure to cholinesterase-inhibiting drugs pesticides or chemicals.

| Special Reports | Eisler RFamphur Hazards to Fish, Wildlife, and Invertebrates: A Synoptic Review. NTIS/PB94-156767Govt Reports Announcements & Index (GRA&I), Issue 13, (1994). Famphur is administered to livestock by intramuscular or subcutaneous injections through the diet, as a dermal pour-on, or as an oral bolus. |
| RCRA-Anforderungen | P097As stipulated in 40 CFR 261.33, when famphur, as a commercial chemical product or manufacturing chemical intermediate or an off-specification commercial chemical product or a manufacturing chemical intermediate, becomes a waste, it must be managed according to federal and/or state hazardous waste regulations. Also defined as a hazardous waste is any container or inner liner used to hold this waste or any residue, contaminated soil, water, or other debris resulting from the cleanup of a spill, into water or on dry land, of this waste. Generators of small quantities of this waste may qualify for partial exclusion from hazardous waste regulations (40 CFR 261.5(e)). |
| FIFRA-Anforderungen | Tolerances are established for residues of the insecticide O,O-dimethyl-O-p-(dimethylsulfamoyl) phenyl phosphorothioate including its oxygen analog (O,O-dimethyl-O-p-(dimethylsulfamoyl) phenyl phosphate) in or on the raw agricultural commodities meat, fat, and meat by products of cattle.As the federal pesticide law FIFRA directs, EPA is conducting a comprehensive review of older pesticides to consider their health and environmental effects and make decisions about their future use. Under this pesticide reregistration program, EPA examines health and safety data for pesticide active ingredients initially registered before November 1, 1984, and determines whether they are eligible for reregistration. In addition, all pesticides must meet the new safety standard of the Food Quality Protection Act of 1996. Pesticides for which EPA had not issued Registration Standards prior to the effective date of FIFRA, as amended in 1988, were divided into three lists based upon their potential for human exposure and other factors, with List B containing pesticides of greater concern and List D pesticides of less concern. Famphur (O,O-dimethyl O-(p-(dimethylsulfamoyl)phenyl) phosph is found on List D. Case No: 4039Case Status: No products containing the pesticide are actively registered ... The case /is characterized/ as "cancelled." Under FIFRA, pesticide producers may voluntarily cancel their registered products. EPA also may cancel pesticide registrations if registrants fail to pay required fees or make/meet certain reregistration commitments, or if EPA reaches findings of unreasonable adverse effects.Active ingredient (AI): Famphur (O,O-dimethyl O-(p-(dimethylsulfamoyl)phenyl) phosphAI Status: The active ingredient is no longer contained in any registered pesticide products ... "cancelled." |
| Reactivity Profile | Organothiophosphates, such as FAMPHUR, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides. |

| Umweltverhalten | TERRESTRIAL FATE: Based on a calculated log Kow of 2.28 obtain from its water solubility(1,2), a soil adsorption coefficient (Koc) of 419 can be obtained for famphur(2,SRC). This value suggests that famphur will display moderate mobility in soil(3), and may be expected to adsorb to soil(SRC). Hydrolysis in moist soils may occur by analogy to its behavior in water(4), however, it is not expected to be a rapid fate process(SRC).AQUATIC FATE: Hydrolysis under neutral conditions is expected to occur slowly, as an experimental half-life of 115 days has been obtained(1). Hydrolysis in basic waters is expected to occur at a more rapid rate, with an experimental half-life of 6 and 60 days at pH 11 and pH 10, respectively(1,SRC). A calculated Koc of 419(2,SRC), based on the estimated log Kow, 2.289(3), suggests that famphur would be expected to adsorb to sediment and suspended organic matter(SRC). A calculated bioconcentration factor of 31.8(2,SRC), also based on log Kow(3), suggests that bioconcentration in fish and aquatic organisms is not expected to be a significant fate process(SRC). |

| Milk Concentrations | IN MILK FROM COWS TREATED WITH 23 MG FAMPHUR/KG, 76% OF THE FAMPHUR WAS FOUND IN THE BUTTERFAT & A MAX LEVEL (0.237 PPM) IN WHOLE MILK WAS FOUND IN THE FIRST MILKING AFTER TREATMENT. RESIDUES WERE NEGLIGIBLE (0.008 PPM) BY THE THIRD DAY. |
| Soil Adsorption/Mobility | Based on a calculated log Kow of 2.28 obtain from its water solubility(1,2), a soil adsorption coefficient (Koc) of 419 can be obtained for famphur(2,SRC). This value suggests that famphur will display moderate mobility in soil(3), and may be expected to adsorb to soil(SRC). |
| Natural Pollution Sources | Famphur is a chemical of anthropogenic origin, and it is not believed to be produced in nature. (SRC) |
| Human Toxicity Excerpts | Veterinarians treating grub infestations in cattle with pour-on applications of famphur and other organic phosphorus pesticides in poorly ventilated areas occasionally reported nausea, headaches, and irritation of the throat and facial skin. Blood cholinesterase activities were not reduced in these cases, and alkyl phosphate metabolites were only occasionally found in the urine. |
| Artificial Pollution Sources | Famphur was produced commercially for use as an insecticide, and in the control of cattle grubs, reindeer grub fly, the reindeer nostril fly, and to reduce lice infestations(1,2). It may have entered the environment as a fugitive emission during its manufacture and formulation, or as a result of its application to control pests(SRC). The EPA lists famphur's status as cancelled(3). |
| Environmental Bioconcentration | Based on a calculated log Kow of 2.28(1), a bioconcentration factor of 31.8 can be obtained for famphur(2,SRC). This value suggests that bioaccumulation in fish and aquatic organisms is not expected to be a significant fate process(SRC). |

| Environmental Abiotic Degradation | An experimental rate constant for the hydrolysis of famphur under neutral conditions at 25 °C has been determined to be 2.5X10-4 1/hr, corresponding to a calculated half life of 115 days(1). The rate constant for hydrolysis under basic conditions at 25 °C has been determined to be 5 l/m hr at pH 11 (1), which corresponds to a half-life of approximately 6, and 60 days at pH 11 and pH 10, respectively(SRC). |
| Probable Routes of Human Exposure | Occupational exposure to famphur may result by dermal contact during its manufacture and formulation into insecticides, or during its application for the control of pests(1,2,SRC). |
