The Henry's Law constant for styrene is reported as 2.75X10-3 atm-cu m/mole(1). This Henry's Law constant indicates that styrene is expected to volatilize from water surfaces(2). Under laboratory conditions, 50% of 2 to 10 mg styrene per liter (depth not specified) was lost by volatilization in 1 to 3 hrs in lake water samples and in 6 to 7 hrs in distilled water, respectively(3). In other studies, the level of styrene in water samples fell from 23 to 3.3 and 0.4 mg/L in 2 hrs and 7 days, respectively, and from 46 to 12.5 and 1.5 mg/L in 2 hrs and 10 days, respectively(4). These findings are relevant to surface waters but not to deeper waters(4). The volatilization half-life of styrene in Rhine River water was 14 days(5). Volatilization of styrene from moist soil surfaces would be slower than in water(4). Samples at 1.5 cm deep of a loamy soil, 26% of 2 mg/kg styrene added volatilized in 31 days(3). The transfer to the air was even slower and less extensive from deep soil(4). The potential for volatilization of styrene from dry soil surfaces may exist(SRC) based upon a vapor pressure of 6.4 mm Hg(6).

The log Koc of styrene is reported to be 2.96(1). According to a classification scheme(2), this Koc value suggests that styrene is expected to have low mobility in soil. More than 85% of styrene is sorbed in 78 hrs on samples from a sandy aquifer(3). Styrene is retained by particulates particularly in organic matter-rich soils(3). Of styrene that had been allowed to sorb for 3 days, 61.0 and 66.7% was desorbed in 16 days from soil and aquifer soils, respectively(4).
