The Henry's Law constant for methyl thiocyanate is estimated as 4.4X10-5 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This value indicates that methyl thiocyanate will volatilize from water surfaces(2,SRC). 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) is estimated as approximately 20 hours(2,SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec) is estimated as approximately 8.6 days(2,SRC). Methyl thiocyanate's Henry's Law constant(1,SRC) indicates that volatilization from moist soil surfaces is expected (SRC). The potential for volatilization of methyl thiocyanate from dry soil surfaces may exist(SRC) based on a measured vapor pressure of 12 mm Hg(4).

Using a structure estimation method based on molecular connectivity indices(1), the Koc for methyl thiocyanate can be estimated to be about 8.3(SRC). According to a recommended classification scheme(2), this estimated Koc value suggests that methyl thiocyanate is expected to have very high mobility in soil(SRC).
