The Henry's Law constant for methyl chloride is 8.82X10-3 atm-cu m/mole(1). This Henry's Law constant indicates that methyl chloride is expected to volatilize rapidly from water 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 2.1 hours(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 2.8 days(SRC). Methyl chloride's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Methyl chloride is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 4,300 mm Hg at 25 deg C(3).

Literature: #The volatilization half-life for 1 ppm methyl chloride from a stirred beaker 6.5 cm deep is 27.6 min(1) which converts to a half-life at a 1 m depth of 7.1 hr(SRC). According to a mathematical model, the cumulative volatilization loss of methyl chloride during the first year after placement 1 m beneath the ground, assuming no water evaporation, is 66.9% and 22.3% for sandy and clay soil, respectively(2). When the buried methyl chloride is subject to 0.1 cm/day of steady upward water flow (water evaporation) the cumulative loss at the end of a year is 77.0% for sandy soil and 42.7% for clay soil(SRC).

Using a structure estimation method based on molecular connectivity indices(1), the Koc for methyl chloride can be estimated to be 13(SRC). According to a classification scheme(2), this estimated Koc value suggests that methyl chloride is expected to have very high mobility in soil.
