| FIFRA 要件 | 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. Daminozide is found on List A, which contains most food use pesticides and consists of the 194 chemical cases (or 350 individual active ingredients) for which EPA issued registration standards prior to FIFRA '88. Case No: 0032Pesticide type: herbicide (growth regulator)Registration Standard Date: 06/30/84 PB87-104782Case Status: RED Approved 09/93OPP 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): daminozideAI Status: OPP has completed a Reregistration Eligibility Decision (RED) for the case/AI.Based on reviews of the generic data for the active ingredient daminozide, the Agency has sufficient information on the health effects of daminozide and on its potential for causing adverse effects in fish and wildlife and the environment. The Agency concludes that products containing daminozide for use in enclosed commercial structures such as greenhouses, shadehouses and interiorscapes are eligible for reregistration. The Agency has determined that daminozide products, labeled and used as specified in this Reregistration Eligibility Decision, will not pose unreasonable risks or adverse effects to humans or the environment.Criteria of Concern: Oncogenicity. Action/Use Affected: Cancelled, all daminozide products, for food uses. Remaining registrations for nonfood uses include cut chrysanthemums and bedding plants. Special review of nonfood uses continued, pending an evaluation of the cancer studies in rats and mice with unsymmetrical dimethyl hydrazine, a degradate and metabolite of daminozide.Existing Stocks Provisions: The sale, distribution, shipment, and use of existing stocks of daminozide for food uses is prohibited in the USA. |

| 環境中動態 | TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 4(SRC), determined from a log Kow of -1.5(2) and a regression-derived equation(3), indicates that daminozide is expected to have very high mobility in soil(SRC). The pKa of daminozide is 4.68(2), suggesting that this compound will exist primarily as an anion in moist soil surfaces, and anions will not volatilize(SRC). Volatilization from dry soil surfaces is not expected(SRC) based upon a vapor pressure of 2X10-4 mm Hg(4). Daminozide is degraded in soil with a major degradation product of being unsymmetrical 1,1-dimethylhydrazide(5). In greenhouse studies, the persistence half-life of daminozide was found to range from 3 to 4 days in four different soils(6).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 4(SRC), determined from a log Kow of -1.5(2) and a regression-derived equation(3), indicates that daminozide is not expected to adsorb to suspended solids and sediment(SRC). The pKa of daminozide is 4.68(2), which suggests that this compound exists primarily as an anion in water surfaces and anions will not volatilize(SRC). According to a classification scheme(4), an estimated BCF of 3(SRC), from its log Kow(2) and a regression-derived equation(5), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Soil studies under aerobic conditions suggest that this compound biodegrades rapidly(6,7), suggesting biodegradation under aerobic conditions in water may also be an important environmental fate process(SRC). No measurable hydrolysis of daminozide was noted at pH 5, 7, and 9(7), but sensitized photolysis was observed(8), suggesting that photolysis in sunlit surface waters may occur(SRC).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), daminozide, which has a vapor pressure of 2X10-4 mm Hg at 23 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase daminozide is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC)the half-life for this reaction in air is estimated to be 32 hours(SRC), calculated from its rate constant of 1.2X10-11 cu cm/molecule-sec at 25 °C (SRC) that was derived using a structure estimation method(3). |
| 食品調査値 | Daminozide has been detected, by FDA's Pesticide Residue Monitoring Program, in U.S. foods during fiscal years 1978-1990(1-4)however, the concns and the frequencies of occurrence were not reported(1-4). The US Food and Drug Administration conducted a survey in 1986 to determine whether samples of fruits and fruit products contained residues of daminozide(5)max residue levels detected were as follows(5): 0.6 ppm in stored fresh apples, 0.8 ppm in applesauce, 1.1 ppm in apple juice, 3.6 ppm in frozen cherries, and 5.9 ppm in canned cherries(5)no detections (detection limit of 0.2 ppm) were found in grape juice samples(5). |

| Soil Adsorption/Mobility | The Koc of daminozide is estimated as 4(SRC), using a log Kow of -1.5(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that daminozide is expected to have very high mobility in soil(SRC). |
| Artificial Pollution Sources | Daminozide's production may result in its release to the environment through various waste streamsit's use as a plant growth regulator(1,2) will result in its direct release to the environment(SRC). Prior use to improve the yield and quality of apples, cherries, and other fruits and vegetables has largely been curtailed because of perceived risks to children and other consumers(3). Owing to its use in greenhouses, nurseries, and other applications, daminozide is still one of the most heavily used plant growth regulators in the US(3). |
