| 환경 거동 | TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 390(SRC), determined from a structure estimation method(2), indicates that tris(2-chloroethyl) phosphate is expected to have moderate mobility in soil(SRC). Volatilization of tris(2-chloroethyl) phosphate from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 3.3X10-6 atm-cu m/mole(SRC), based upon its vapor pressure, 6.13X10-2 mm Hg(3), and water solubility, 7000 mg/L(4). Tris(2-chloroethyl) phosphate is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(3). A 4% of theoretical BOD using activated sludge in the Japanese MITI test(5) suggests that biodegradation is not an important environmental fate process in soil(SRC).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 390(SRC), determined from a structure estimation method(2), indicates that tris(2-chloroethyl) phosphate is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 3.3X10-6 atm-cu m/mole(SRC), derived from its vapor pressure, 6.13X10-2 mm Hg(4), and water solubility, 7000 mg/L(5). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 19 and 140 days, respectively(SRC). Tris(2-chloroethyl) phosphate may undergo hydrolysis in the environment based on an estimated hydrolysis half-life of 20 days at pH 5 to 9(2). According to a classification scheme(6), measured BCF values of 0.6-5.1 in fish(7-9), suggest bioconcentration in aquatic organisms is low(SRC). A 4% of theoretical BOD using activated sludge in the Japanese MITI test(7) suggests that biodegradation is not an important environmental fate process in water(SRC).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), tris(2-chloroethyl) phosphate, which has a vapor pressure of 6.13X10-2 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase tris(2-chloroethyl) phosphate 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 16 hours(SRC), calculated from its rate constant of 2.2X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Tris(2-chloroethyl) phosphate does not contain chromophores that absorb at wavelengths >290 nm(4) and, therefore, is not expected to be susceptible to direct photolysis by sunlight(SRC). |

| 독성 요약 | IDENTIFICATION AND USE: (Tris(2-chloroethyl) phosphate is a Clear, transparent liquid. It is used primarily as an additive plasticizer and viscosity regulator with flame-retarding properties for polyurethane, polyesters, polyvinyl chloride and other polymers. HUMAN EXPOSURE AND TOXICITY: Tris(2-chloroethyl) phosphate did not consistently demonstrate detectable unscheduled DNA synthesis with and without metabolic activation and failed to show a dose-response relationship in human WI-38 cells. ANIMAL STUDIES: In repeat dose studies Tris(2-chloroethyl) phosphate caused adverse effects on the brain (hippocampal lesions in rats), liver and kidneys. Non-irritant to eyes, but conflicting reports in the literature on skin irritation, has not been tested for sensitization potential. Not teratogenic. It adversely affects the fertility of male rats and mice. In vitro mutagenicity test results were inconsistent and an in vivo micronucleus test gave equivocal results. Tris(2-chloroethyl) phosphate causes benign and malignant tumors at various organ sites in rats and mice. A very high oral dose caused some inhibition of plasma cholinesterase and brain neuropathy target esterase, but did not cause delayed neurotoxicity. In rats, a high dose caused convulsions, brain lesions and impaired performance. Metabolites in rats and mice include bis(2-chloroethyl)carboxymethyl phosphatebis(2-chloroethyl) hydrogen phosphateand bis(2-chloroethyl)-2-hydroxyethyl phosphate glucuronide excreted mainly via the urine. |
