- Environmental Bioconcentration: An estimated BCF value of 62 was calculated for 1-methoxy-4-methylbenzene(SRC), using an experimental log Kow of 2.66(1) and a recommended regression-derived equation(2). According to a recommended classification scheme(3), this BCF value suggests that 1-methoxy-4-methylbenzene will bioconcentrate moderately in aquatic organisms(SRC). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: TERRESTRIAL FATE: Based on a recommended classification scheme(1), an estimated Koc value of 670(SRC), determined from an experimental log Kow(2) and a recommended regression-derived equation(3), indicates that 1-methoxy-4-methylbenzene will have low mobility in soil(SRC). Volatilization of 1-methoxy-4-methylbenzene may be important from moist soil surfaces(SRC) given an estimated Henry's Law constant of 4.7X10-3 atm-cu m/mole(4,SRC), and from dry soil surfaces(SRC) based on an estimated vapor pressure of 1.14 mm Hg(5,SRC). Insufficient data are available to determine the rate or importance of biodegradation of 1-methoxy-4-methylbenzene in soil(SRC). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: AQUATIC FATE: Based on a recommended classification scheme(1), an estimated Koc value of 670(SRC), determined from an experimental log Kow(2) and a recommended regression-derived equation(3), indicates that 1-methoxy-4-methylbenzene may adsorb to suspended solids and sediment(SRC) in water. 1-Methoxy-4-methylbenzene may volatilize from water surfaces based on an estimated Henry's Law constant of 4.7X10-3 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). Estimated half-lives for a model river and model lake are 3.4 hours and 4.4 days, respectively(3,SRC). An estimated BCF value of 62(3,SRC), from an experimental log Kow(2), suggests that 1-methoxy-4-methylbenzene will only bioconcentrate moderately in aquatic organisms(SRC) according to a recommended classification scheme(5). Insufficient data are available to determine the rate or importance of biodegradation of 1-methoxy-4-methylbenzene in water(SRC). Source: Hazardous Substances Data Bank (HSDB)
- Environmental Fate: ATMOSPHERIC FATE: According to a suggested classification scheme(1), an estimated vapor pressure of 1.1 mm Hg at 25 °C(2,SRC) indicates that 1-methoxy-4-methylbenzene will exist in the vapor phase in the ambient atmosphere. Vapor-phase 1-methoxy-4-methylbenzene 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 14 hours(3,SRC).
