- Environmental Bioconcentration: An estimated BCF value of 0.4 was calculated for 1,2-dimethoxyethane(SRC), using a measured log Kow of -0.21(1) and a recommended regression-derived equation(2). According to a classification scheme(3), this BCF value suggests that bioconcentration in aquatic organisms will be low(SRC). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: TERRESTRIAL FATE: Based on a recommended classification scheme(1), an estimated Koc value of 18(SRC), determined from a measured log Kow(2) and a recommended regression-derived equation(3), indicates that 1,2-dimethoxyethane will have very high mobility in soil(SRC). Limited data, based on pure culture studies(4), suggest that this compound may be resistant to biodegradation(SRC). Volatilization of 1,2-dimethoxyethane may be important from dry soil surfaces(SRC) based on a measured vapor pressure of 48 mm Hg(5), but not from moist soil surfaces(SRC) given an estimated Henry's Law constant of 1.1X10-6 atm-cu m/mole(6,SRC). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: AQUATIC FATE: Based on a recommended classification scheme(1), an estimated Koc value of 18(SRC), determined from a measured log Kow(2) and a recommended regression-derived equation(3), indicates that 1,2-dimethoxyethane should not adsorb to suspended solids and sediment(SRC) in the water. Limited data, from pure culture studies(4), suggest that this compound may be resistant to biodegradation(SRC). 1,2-Dimethoxyethane may volatilize slowly from water surfaces based on an estimated Henry's Law constant of 1.1X10-6 atm-cu m/mole(SRC), developed using a fragment constant estimation method(5). Estimated half-lives for a model river and model lake are 33 and 240 days, respectively(3,SRC). According to a recommended classification scheme(6), an estimated BCF value of 0.4(3,SRC), from a measured log Kow(2), suggests that bioconcentration of 1,2-dimethoxyethane will be low in aquatic organisms(SRC). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: ATMOSPHERIC FATE: According to a suggested classification scheme(1), a measured vapor pressure of 48 mm Hg at 20 °C(2) indicates that 1,2-dimethoxyethane will mainly exist in the vapor phase in the ambient atmosphere. Vapor-phase 1,2-dimethoxyethane 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 25 hours(3,SRC).
