The Henry's Law constant for 4-methylbenzaldehyde is estimated as 1.7X10-5 atm-cu m/mole(SRC), derived from its vapor pressure, 0.25 mm Hg(1), and water solubility, 2270 mg/L(2). This Henry's Law constant indicates that 4-methylbenzaldehyde 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 2.4 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 21 days(SRC). 4-Methylbenzaldehyde's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). 4-Methylbenzaldehyde is expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(1).

The Koc of 4-methylbenzaldehyde is estimated as 62(SRC), using a water solubility of 2,270 mg/L(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 4-methylbenzaldehyde is expected to have high mobility in soil.
