The Henry's Law constant for methyl ethyl ketone is 4.67X10-5 atm-cu m/mole(1). This Henry's Law constant indicates that methyl ethyl ketone is expected to volatilize 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 18 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 8.2 days(SRC). Methyl ethyl ketone's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Methyl ethyl ketone is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 90.6 mm Hg(3). The volatilization half-life of methyl ethyl ketone from silt and sandy loams was measured as 4.9 days(4).

Measured Koc values of 29 and 34 were obtained for methyl ethyl ketone in a silt loam and sandy loam soil respectively(1). A measured Koc value of 3.55 has also been reported(2). According to a classification scheme(3), these Koc values suggest that methyl ethyl ketone is expected to have very high mobility in soil(SRC).
