| Volatilization | The Henry's Law constant for acetamide is estimated as 2.0X10-9 atm-cu m/mole(SRC) derived from its vapor pressure, 0.018 mm Hg(1), and water solubility, 7.05E10+5 mg/L(2). This Henry's Law constant indicates that acetamide is expected to be essentially nonvolatile from water surfaces(3). Acetamide's estimated Henry's Law constant indicates that volatilization from moist soil surfaces is not expected to occur(SRC). Acetamide is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure. Evaporation of acetamide at 20 deg C is reported to be negligible(4).

| Soil Adsorption | An experimental Koc of 5 has been reported for acetamide(1). According to a classification scheme(2), this Koc value suggests that acetamide is expected to have very high mobility in soil.
