Volatilization | The Henry's Law constant for glycolonitrile is estimated as 7.4X10-6 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that glycolonitrile is not 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 61 hrs(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 30 days(SRC). Glycolonitrile's Henry's Law constant(1) indicates that volatilization from moist soil surfaces may occur(SRC). Glycolonitrile is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 0.8 mm Hg(3). |
Soil Adsorption | Using a structure estimation method based on molecular connectivity indices(1), the Koc for glycolonitrile can be estimated to be about 1(SRC). According to a classification scheme(2), this estimated Koc value suggests that glycolonitrile is expected to have very high mobility in soil. |
