| Volatilization | The Henry's Law constant for 1-nonanol estimated as 3.08X10-5 atm-cu m/mol(SRC) derived from its vapor pressure, 2.27X10-2 mm Hg at 25 deg C(1), and water solubility, 140 mg/L(2). This Henry's Law constant indicates that 1-nonanol is expected to volatilize from water surfaces(3). 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)(3) is estimated as 1.6 days(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(3) is estimated as 15 days(SRC). 1-Nonanol's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). 1-Nonanol is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(1).

| Soil Adsorption | An estimated BCF of 160 was calculated for 1-nonanol(SRC), using a log Kow of 3.77(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is high(SRC), provided the compound is not metabolized by the organism(SRC).
