The Henry's Law constant for methyl nitrite is estimated as 6.6X10-5 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that methyl nitrite 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 7.8 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 6.2 days(SRC). Methyl nitrite's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of methyl nitrite from dry soil surfaces may exist(SRC) based upon an estimated vapor pressure of 1,600 mm Hg(SRC), determined from a fragment constant method(3).

Using a structure estimation method based on molecular connectivity indices(1), the Koc for methyl nitrite can be estimated to be 44(SRC). According to a classification scheme(2), this estimated Koc value suggests that methyl nitrite is expected to have very high mobility in soil.
