| Volatilization | A Henry's Law constant of 1.0X10-5 atm-cu m/mole at 25 deg C(1) indicates that volatilization of cyclopentanone from natural bodies of water should be an important fate process(2). Based upon this Henry's Law constant, the volatilization half-life from a model river (1 meter deep flowing 1 m/sec with a wind speed of 3 m/sec) has been estimated to be 3.5 days(2,SRC). The volatilization half-life from a model pond, which considers the effect of adsorption, has been estimated to be about 40 days(3,SRC). Based on the vapor pressure of 11.4 mm Hg at 25 deg C(4), cyclopentanone should evaporate from dry surfaces, especially when present in high concn such as in spill situations(SRC).

| Soil Adsorption | Based on an estimated water solubility of 9175 mg/L(1), a Koc value of 30 for cyclopentanone has been calculated from a regression-derived equation(1,SRC). This Koc value indicates cyclopentanone should be very highly mobile in soil(2).
