Volatilization | The Henry's Law constant for trans-1,3-pentadiene is estimated as 0.12 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This Henry's Law constant indicates that trans-1,3-pentadiene 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 51 min(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 3.3 days(SRC). trans-1,3-Pentadiene's Henry's Law constant(1) indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of trans-1,3-pentadiene from dry soil surfaces may exist based upon a vapor pressure of 411 mm Hg(3).

This Henry's Law constant indicates that 1,3-pentadiene 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 1 hour(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 78 hours(SRC). 1,3-Pentadiene's Henry's Law constant(1) indicates that volatilization from moist soil surfaces may occur(SRC). The potential for volatilization of 1,3-pentadiene from dry soil surfaces exists based upon a vapor pressure of 405 mm Hg(3).

Soil Adsorption | The Koc of trans-1,3-pentadiene is estimated as 500(SRC), using a measured log Kow of 2.44(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that trans-1,3-pentadiene is expected to have low mobility in soil(SRC). Literature: (1) Sangster J; LOGKOW Databank.
