The Henry's Law constant for 1,2,3- benzotriazole is estimated as 3.2X10-7 atm-cu m/mole(SRC) derived from its vapor pressure, 0.04 mm Hg(1), and water solubility, 19,800 mg/l(1). This Henry's Law constant indicates that 1,2,3-benzotriazole is expected to be essentially nonvolatile from water surfaces(2). 1,2,3-Benzotriazole is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(1). The pKa of benzotriazole is 8.37(3), indicating that this compound will exist in the cation form in the environment. Volatilization from dry or moist soil surfaces is not expected to be an important fate process because the cation is not expected to volatilize.

The Koc of 1,2,3-benzotriazole is estimated as 145(SRC), using a log Kow of 1.44(1) and a regression-derived equation(2). According to a classification scheme(3), these estimated Koc values suggests that 1,2,3- benzotriazole is expected to have high mobility in soil. However, mobility of 1,2,3-benzotriazole will be affected by pH(2): the pKa of benzotriazole is 8.37(4), indicating that this compound will exist in the cation form in the environment and cations generally adsorb to organic carbon and clay more strongly than their neutral counterparts.
