- Environmental Bioconcentration: An estimated BCF value of 400 was calculated for 2-ethylhexyl acetate(SRC), using an estimated log Kow of 3.74(1) and a recommended regression-derived equation(2). According to a classification scheme(3), this BCF value suggests that bioconcentration in aquatic organisms is high(SRC). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: TERRESTRIAL FATE: Based on a recommended classification scheme(1), an estimated Koc value of 2,500(SRC), determined from an estimated log Kow of 3.74(2,SRC) and a recommended regression-derived equation(3), indicates that 2-ethylhexyl acetate is expected to have slight mobility in soil(SRC). Volatilization of 2-ethylhexyl acetate is expected from moist soil surfaces(SRC) given its estimated Henry's Law constant of 1.5X10-3 atm-cu m/mole(SRC) using a fragment constant estimation method(4). Volatilization from dry soil surfaces is expected based on a vapor pressure of 0.23 mm Hg at 25 °C(5). Although no biodegradation studies have been performed on 2-ethylhexyl acetate, studies on structurally similar compounds(6-8) have shown that, in general, alkyl acetates are biodegradable(SRC).

- Environmental Fate: AQUATIC FATE: Based on a recommended classification scheme(1), an estimated Koc value of 2,500(SRC), determined from an estimated log Kow of 3.74(2) and a recommended regression-derived equation(3), indicates that 2-ethylhexyl acetate is expected to adsorb to suspended solids and sediment in water(SRC). 2-Ethylhexyl acetate is expected to volatilize from water surfaces(3,SRC) based on an estimated Henry's Law constant of 1.5X10-3 atm-cu m/mole(SRC) using a fragment constant estimation method(4). Estimated volatilization half-lives for a model river and model lake are 5 and 130, hours respectively(4,SRC). According to a classification scheme(5), an estimated BCF value of 400(3,SRC), from its log Kow(2), suggests that bioconcentration in aquatic organisms is high(SRC). Hydrolysis is expected to occur slowly based upon estimated hydrolysis half-lives of 3 years and 122 days at pH 7 and 8 respectively(6,SRC). Although no biodegradation studies have been performed on 2-ethylhexyl acetate, studies on structurally similar compounds(7-9) have shown that, in general, alkyl acetates are biodegradable(SRC).

- Environmental Fate: ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 2-ethylhexyl acetate, which has a vapor pressure of 0.23 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 2-ethylhexyl acetate is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be about 35 hours(3,SRC).
