FIFRA 요건	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. Ammonium ethyl carbamolyphosphonate is found on List B. Case No: 2355Pesticide type: HerbicideCase Status: RED Approved 12/94OPP has made a decision that some/all uses of the pesticide are eligible for reregistration, as reflected in a Reregistration Eligibility Decision (RED) document.Active ingredient (AI): Ammonium ethyl carbamolyphosphonateData Call-in (DCI) Date(s): 06/11/91, 03/14/95AI Status: OPP has completed a Reregistration Eligibility Decision (RED) document for the case/AI.

Soil Adsorption/Mobility	In field studies (conducted in DE, FL, and IL), greenhouse studies, and soil column studies, fosamine-ammonium was found to leach very little, either downward or laterally(1)most undegraded fosamine-ammonium remained in the upper 4 inches of soil(1).

Environmental Biodegradation	Laboratory studies in biometer flasks on two soil types (pHs of 6.4 and 6.5) treated with C-14 fosamine-ammonium demonstrated rapid degradation by microbial action(1)14-CO2 evolution in nonsterile soils reached 45-75% after 90 days(1)in soil sterilized by a single autoclaving at steam pressure for 15 min, 14-CO2 evolution was only 8-18%(2).

Environmental Bioconcentration

Based upon a water solubility of 1.79 kg/L at 25 °C(1), the BCF of fosamine-ammonium can be estimated to be 0.2 from a recommended regression derived equation(2,SRC). The BCF value indicates that bioconcentration in aquatic organisms is not an important fate process(SRC). In bioaccumulation studies using channel catfish and (14)C fosamine-ammonium, fosamine-ammonium BCFs of less than 1 were measured(2).

Volatilization from Water/Soil	Based upon a vapor pressure of 4X10-6 mm Hg(1) and a water solubility of 1.79 kg/l at 25 °C(1), the Henry's Law constant for fosamine-ammonium can be estimated to be 5X10-13 atm-cu m/mole (SRC). This value of Henry's Law constant indicates that fosamine-ammonium is essentially nonvolatile from water(2).

Non-Human Toxicity Excerpts

... The emulsifiable concentrate with or without surfactant is not an irritant of eyes and skin of rabbits. In 90 day feeding trials in rats no adverse effects were detected at 1000 mg active ingredient/kg diet.STATIC 96 HR MEDIAN LETHAL CONCN FOR 12 WATER SOLUBLE HERBICIDES WITH YEARLING COHO SALMON IN FRESHWATER INCL KRENITE WAS MORE THAN 200 MG/L.RESIDUES IN CHANNEL CATFISH EXPOSED TO 1.1 PPM FOR 4 WK WERE FOUND TO PLATEAU IN 2-3 WK WITH AN ACCUMULATION FACTOR OF LESS THAN 1. NO ADVERSE EFFECTS ON THE FISH OBSERVED DURING THESE EXPERIMENTS.No pathological changes upon feeding to rats at 10000 mg/kg body wt for 90 days.Fosamine ammonium has been reported to be teratogenic to avian embryos following spray application of the eggs. The embryotoxic and teratogenic potential of fosamine ammonium was examined in mallards (Anas platyrhynchos) and bobwhite (Colinus virginianus). At 96 hr of development, eggs were briefly immersed in distilled water or in fosamine ammonium formulation in distilled water at concentrations of 1.5, 6.5, or 30% fosamine ammonium. At 6.5% ai, fosamine ammonium reduced hatching success in bobwhite and mallards to 85 and 33% of that in the distilled water controls. At 30% ai, fosamine ammonium caused 95 to 100% mortality in both species by the time of hatching. Early embryonic growth was impaired by 30% fosamine ammonium in both species. There was no evidence of teratogenesis of the axial skeleton, as reported previously in chickens and Japanese quail (Coturnix japonica). Most abnormal embryos had severe edema and some stunting. Mallard hatchlings from the 1.5 and 6.5% fosamine ammonium groups weighed significantly less than controls and had lower plasma alanine aminotransferase and aspartate aminotransferase activities, with elevated plasma glucose and cholesterol concentrations. Brain acetylcholinesterase activity was unaffected by fosamine ammonium in embryos and hatchlings. /Fosamine ammonium/

Environmental Abiotic Degradation

The rate constant for the vapor phase reaction of fosamine-ammonium with photochemically produced hydroxyl radicals has been estimated to be 4.9X10-11 cu cm/molecule-sec at 25 °C which corresponds to an atmospheric half-life of about 7.9 hours at an atmospheric concn of 5X10+5 hydroxyl radicals per cu cm(1,SRC). In aqueous hydrolysis studies using buffered water at 20 °C, less than 3% of initial fosamine-ammonium degraded over a 4 week period at pHs of 7 and 9(2)however, at pH 5, a degradation half-life of about 10 days was observed(2). Fosamine-ammonium was found to be stable (less than 2% degradation over 4 weeks) to direct photolysis and photosensitized photolysis (using riboflavin and anthraquinone sensitizers) in photolysis studies using sunlight and water at pH 7.9 and a Brandywine River water at pH 6.5(2)when sediments were added to the river water, degradation reached 45% after 4 weeks, but the degradation process was considered to be biological(2).

Probable Routes of Human Exposure	Occupational exposure to fosamine-ammonium occurs through dermal contact and inhalation of dust and sprays, especially to workers applying the compound as a herbicide(1).

Environmental Fate/Exposure Summary

Fosamine-ammonium's use as a contact herbicide releases the compound directly tothe environment through applications in sprays and other routes of application. If released to the atmosphere, fosamine-ammonium will degrade rapidly in the vapor phase by reaction with photochemically produced hydroxyl radicals (half-life of about 7.9 hr). Particulate phase fosamine-ammonium will be removed physically from air by wet and dry deposition. If released to soil or water, fosamine-ammonium can degrade through biodegradation and aqueous hydrolysishowever, hydrolysis will be important only in very acidic soils and water. Results of field, greenhouse and soil column studies have demonstrated that fosamine-ammonium is unlikely to leach under environmental conditions. Field and greenhouse persistence studies have found soil half-lives of about one week to 10 dayscarbamoyl phosphonic acid has been identified as a fosamine-ammonium metabolite. Occupational exposure to fosamine-ammonium occurs through dermal contact and inhalation of dust and sprays, especially to workers applying the compound as a herbicide. (SRC)
