Results and discussion

Any other information on results incl. tables

The Henry's Law constant for the test substance is estimated as 7.6E-3 atm-m3/mole (SRC, n.d.) from its vapor pressure, 4450 mm Hg, and water solubility, 4.6E4 mg/L (Hine and Mookerjee, 1975). This Henry's Law constant indicates that the test substance is expected to volatilize rapidly from water surfaces (Lyman et al., 1990; SRC, n.d.). Based on this Henry's Law constant, the estimated volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec) is approximately 2.1 hours (Lyman et al., 1990; SRC, n.d.). The estimated volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec) is approximately 2.7 days (Lyman et al., 1990; SRC, n.d).
