TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 700(SRC), determined from a structure estimation method(2), indicates that 1,3-dichloro-1,1,2,2,3-pentafluoropropane is expected to have low mobility in soil(SRC). Volatilization of 1,3-dichloro-1,1,2,2,3-pentafluoropropane from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 2.76 atm-cu m/mole(SRC), using a fragment constant estimation method(3). The potential for volatilization of 1,3-dichloro-1,1,2,2,3-pentafluoropropane from dry soil surfaces may exist(SRC) based upon a vapor pressure of 286 mm Hg(4). 1,3-Dichloro-1,1,2,2,3-pentafluoropropane, achieved 15% of its theoretical BOD in a 28 day closed bottle test, and it is expected that biodegradation will occur much less rapidly than volatilization in soil(4).

AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 700(SRC), determined from a structure estimation method(2), indicates that 1,3-dichloro-1,1,2,2,3-pentafluoropropane 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 2.76 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4) Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 1.5 hours and 5.6 days, respectively(SRC). According to a classification scheme(5), an estimated BCF of 50(SRC), from its log Kow of 3.1(6) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is moderate(SRC). 1,3-Dichloro-1,1,2,2,3-pentafluoropropane, present at 9.4 mg/l, reached 15% of its theoretical BOD in a 28 day closed bottle test, and therefore, biodegradation of 1,3-dichloro-1,1,2,2,3-pentafluoropropane is expected to be slow compared to volatilization(6).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 1,3-dichloro-1,1,2,2,3-pentafluoropropane, which has a vapor pressure of 286 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 1,3-dichloro-1,1,2,2,3-pentafluoropropane 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 4.9 years(SRC), calculated from its rate constant of 9.0X10-15 cu cm/molecule-sec at 25 °C(3). Measured absorption coefficients for 1,3-dichloro-1,1,2,2,3-pentafluoropropane indicate that photolysis in the troposphere does not compete with removal by reaction with the hydroxyl radical(4). Stratospheric photolysis, although contributing to the overall atmospheric lifetime, is less important than reactive loss processes. Stratospheric photolysis and reactive loss processes involving 1,3-dichloro-1,1,2,2,3-pentafluoropropane released chlorine radicals which can participate in ozone destroying reactions.

Using a structure estimation method based on molecular connectivity indices(1), the Koc for 1,3-dichloro-1,1,2,2,3-pentafluoropropane can be estimated to be 700(SRC). According to a classification scheme(2), this estimated Koc value suggests that 1,3-dichloro-1,1,2,2,3-pentafluoropropane is expected to have low mobility in soil.

An estimated BCF of 50 was calculated for 1,3-dichloro-1,1,2,2,3-pentafluoropropane(SRC), using a log Kow of 3.1(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate(SRC).

The Henry's Law constant for 1,3-dichloro-1,1,2,2,3-pentafluoropropane is estimated as 2.76 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that 1,3-dichloro-1,1,2,2,3-pentafluoropropane is expected to volatilize rapidly from water surfaces(2). Based on this estimated 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 1.5 hours(SRC).

This corresponds to an atmospheric half-life of about 4.9 years at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(2). 1,3-Dichloro-1,1,2,2,3-pentafluoropropane is not expected to undergo hydrolysis in the environment due to the lack of hydrolyzable functional groups(3). Photolysis of 1,3-dichloro-1,1,2,2,3-pentafluoropropane does not compete with hydroxyl radical reactions in the troposphere, but can become environmentally significant in the stratosphere where released chlorine radicals may participate in ozone-destroying reactions.
