Due to a lack of data, the tendency for methylthiouracil to volatilize from water and moist near-surface soil cannot be estimated(SRC). Based upon a report that the compound readily sublimes(1), however, loss of methylthiouracil from surfaces and dry near-surface soil may occur via sublimation(SRC).

Based upon a water solubility of 533.2 mg/l at 25 °C(1), a Koc of 138 can be calculated for methylthiouracil using a recommended regression equation(2,SRC). Based upon this estimated Koc, methylthiouracil will be expected to be highly mobile in soil(3,SRC) and will not be expected to significantly adsorb to soil, sediment or suspended particulate matter(3,SRC).

Thiourea, Pharmaceutical Secondary Standard; Certified Reference Material

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).
