The Henry's Law constant for 4-xylene is measured as 6.90X10-3 atm-cu m/mole(1). This Henry's Law constant indicates that 4-xylene is expected to volatilize rapidly 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 3.1 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 4.1 days(SRC). 4-Xylene's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). 4-Xylene is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 8.84 mm Hg(3).

Koc values of 246 and 540 have been measured for 4-xylene in silt and sandy loam soils respectively(1). A Koc value of 204 was measured for 4-xylene using sandy aquifer materials(2). A median experimental Koc value of 295 has also been reported(3). According to a classification scheme(4), these Koc values suggest that 4-xylene is expected to have moderate to low mobility in soil. A soil leaching column study estimated a 4-xylene Koc of 331 using a chromatographic methodology(5). Another soil column leaching study estimated a Koc range of 118-298 based on HPLC measurement(6).
