| Volatilization | The Henry's Law constant for anisole estimated to be 4.35X10-3 atm-cu-m/mol(SRC) using a fragment constant estimation method(1). This value indicates that anisole will volatilize rapidly from water(2,SRC). Using this value for the Henry's Law constant, the volatilization half-life from a model river (1 m deep flowing at 1 m/s with a wind speed of 3 m/s) is estimated as 3.2 hr(2,SRC). Similarly, the volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind volocity of 0.5 m/sec) is estimated as 4.2 days(2,SRC). Anisole's moderate vapor pressure, 3.5 mm Hg at 25 deg C(3), low adsorptivity to soil, and high Henry's Law constant(1,SRC) indicate that volatilization from dry and moist soil may occur(SRC).

| Soil Adsorption | An experimental Koc of 35 has been reported for anisole(1). Using an estimation method based on molecular connectivity indices(2), the Koc for anisole is estimated to be 118(SRC). According to a suggested classification scheme(3), these Koc values respectively suggest that anisole would be very highly mobile and highly mobile in soil and would readily leach(SRC).
