The Henry's Law constant for thiourea is estimated as 1.1X10-13 atm-cu m/mole(SRC), derived from its vapor pressure, 1.41X10-7 mm Hg(1), and water solubility, 1.34X10+5 mg/L(2). This Henry's Law constant indicates that thiourea is expected to be essentially nonvolatile from water surfaces(3). Thiourea's estimated Henry's Law constant indicates that volatilization from moist soil surfaces is not expected to occur(SRC). Thiourea is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(1).

Using OECD Guideline 106 (Adsorption - Desorption Using a Batch Equilibrium Method), thiourea had measured Koc values of 28, 26 and 36 in Alfisol (neutral loam), Spodosol (acidic sandy) and Entisol (slightly basic loam) soils respectively(1). A measured Koc value of 7 has also been reported(2). According to a classification scheme(3), these Koc values suggest that thiourea is expected to have very high mobility in soil. In soil column adsorption studies using five Eurosoils, thiourea was used as a tracer due to its minimum interaction with the solid matrix and had Kd values of 0.00 in all five soils(4).
