The Henry's Law constant for 2-methylnaphthalene is reported as 5.18X10-4 atm-cu m/mole(1). This Henry's Law constant indicates that 2-methylnaphthalene is expected to volatilize from water surfaces(2). 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)(2) is estimated as 5.5 hours(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(2) is estimated as 5.3 days(SRC). However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column. The volatilization half-life from a model pond is about 41-78 days when adsorption is considered(3). 2-Methylnaphthalene's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). 2-Methylnaphthalene is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 0.055 mm Hg(4).

A log Koc value of 3.67 was reported in soil(1). An average sediment- or soil-water partition coefficient (log Kp) for 2-methylnaphthalene of 2.00 was determined from 17 measurements(2). The log Koc values for 2-methylnaphthalene in 75 sediment samples was 3.00-5.96(3). Measured Koc values have been reported as 4,400(4) and 8,500(5) for 2-methylnaphthalene. According to a classification scheme(6), these Koc values suggest that 2-methylnaphthalene is expected to have slight to no mobility in soil.
