GHS-EinstufungWarningH400: Very toxic to aquatic life [Warning Hazardous to the aquatic environment, acute hazard]P273, P391, and P501 (click each P-code to see the statement)
FIFRA-AnforderungenAs 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 continued use. Under this pesticide reregistration program, EPA examines newer health and safety data for pesticide active ingredients initially registered before November 1, 1984, and determines whether the use of the pesticide does not pose unreasonable risk in accordance to newer safety standards, such as those described in the Food Quality Protection Act of 1996. Butoxyethyl 2-(2,4-dichlorophenoxy)propionate is found on List A, which contains most pesticides that are used on foods and, hence, have a high potential for human exposure. List A consists of the 194 chemical cases (or 350 individual active ingredients) for which EPA issued registration standards prior to FIFRA '88. Case No: 0294Pesticide type: herbicideRegistration Standard Date: 09/01/88Case Status: OPP is reviewing data from the pesticide's producers regarding its human health and/or environmental effects, or OPP is determining the pesticide's eligibility for reregistration and developing the RED document.Active ingredient (AI): Butoxyethyl 2-(2,4-dichlorophenoxy)propionateData Call-in (DCI) Date(s): 07/26/94, 03/03/95, 10/13/95AI Status: The producers of the pesticide have made commitments to conduct the studies and pay the fees required for reregistration, and are meeting those commitments in a timely manner.

UmweltverhaltenTERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 970(SRC), determined from a structure estimation method(2), indicates that dichlorprop-butotyl is expected to have moderate mobility in soil(SRC). Volatilization of dichlorprop-butotyl from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 1.4X10-7 atm-cu m/mole(SRC), developed using a fragment constant estimation method(3). Dichlorprop-butotyl is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 4.0X10-6 mm Hg at 25 °C(SRC), determined from a fragment constant method(2). Biodegradation data in soil were not available(SRC, 2018).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 970(SRC), determined from a structure estimation method(2), indicates that dichlorprop-butotyl is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(3) based upon an estimated Henry's Law constant of 1.4X10-7 atm-cu m/mole(SRC), developed using a fragment constant estimation method(2). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 470 and 3400 days, respectively(SRC). According to a classification scheme(4), an estimated BCF of 450(SRC), from an estimated log Kow of 4.52(2) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is moderate(SRC). Biodegradation data in water were not available(SRC, 2018).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), dichlorprop-butotyl, which has an estimated vapor pressure of 4.0X10-6 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase dichlorprop-butotyl 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 14 hrs(SRC), calculated from its rate constant of 2.7X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(2). Particulate-phase dichlorprop-butotyl may be removed from the air by wet and dry deposition(SRC). Dichlorprop-butotyl contains chromophores that absorb at wavelengths >290 nm(3) and, therefore, may be susceptible to direct photolysis by sunlight(SRC).
ToxizitätsübersichtIDENTIFICATION AND USE: Dichlorprop-butotyl is no longer produced or used in the US. HUMAN STUDIES: There are no data available. ANIMAL STUDIES: There are no data available.
Soil Adsorption/MobilityUsing a structure estimation method based on molecular connectivity indices(1), the Koc of dichlorprop-butotyl can be estimated to be 970(SRC). According to a classification scheme(2), this estimated Koc value suggests that dichlorprop-butotyl is expected to have low mobility in soil(SRC).
Artificial Pollution SourcesDichlorprop-butotyl's production may result in its release to the environment through various waste streamsits former use as an herbicide(1) resulted in its direct release to the environment(SRC).
Environmental BioconcentrationAn estimated BCF of 450 was calculated in fish for dichlorprop-butotyl(SRC), using an estimated log Kow of 4.52(1) and a regression-derived equation(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is high(SRC).
Volatilization from Water/SoilThe Henry's Law constant for dichlorprop-butotyl is estimated as 1.4X10-7 atm-cu m/mole(SRC) developed using a fragment constant estimation method(1). This Henry's Law constant indicates that dichlorprop-butotyl is expected to be essentially nonvolatile from water and moist soil surfaces(2). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(2) is estimated as 470 days(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(2) is estimated as 3400 days(SRC). Dichlorprop-butotyl is not) expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 4.0X10-6 mm Hg(SRC), determined from a fragment constant method(1).
Environmental Abiotic DegradationThe rate constant for the vapor-phase reaction of dichlorprop-butotyl with photochemically-produced hydroxyl radicals has been estimated as 1.4X10-7 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 14 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). A base-catalyzed second-order hydrolysis rate constant of 2.6 L/mole-sec(SRC) was estimated using a structure estimation method(1)this corresponds to half-lives of 300 and 31 days at pH values of 7 and 8, respectively(1). Dichlorprop-butotyl contains chromophores that absorb at wavelengths >290 nm(2) and, therefore, may be susceptible to direct photolysis by sunlight(SRC).
Environmental Water ConcentrationsWater quality data compiled from the Retrieval (STORET) Data Warehouse and the USGS National Water Information System (NWIS) reports surface water and ground water monitoring data for various chemicals but did not include dichlorprop-butotyl as of 2018(1).
Other Environmental ConcentrationsOccupational exposure and general population exposure should be low or non-existent since dichlorprop-butotyl is no longer produced or used in the US. (SRC)
Environmental Fate/Exposure SummaryDichlorprop-butotyl's production may result in its release to the environment through various waste streamsits former use as an herbicide resulted in its direct release to the environment. If released to air, an estimated vapor pressure of 4.0X10-6 mm Hg at 25 °C indicates dichlorprop-butotyl will exist in both the vapor and particulate phases in the atmosphere. Vapor-phase dichlorprop-butotyl will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicalsthe half-life for this reaction in air is estimated to be 14 hrs.
