Environmental Fate and Exposure Potential
Environmental Fate/Exposure Summary:
TERRESTRIAL FATE: Based on a recommended classification scheme(1), an estimated Koc value of 2300(SRC), determined from a measured log Kow(2) and a recommended regression-derived equation(3), indicates that anthrone will have only slight mobility in soil(SRC). Biodegradation of anthrone is expected based on limited data and may be a major fate process for this compound in soil(SRC). A mixed bacterial population, isolated from a hydrocarbon-polluted creek, degraded 40% of anthrone to traces of anthrone and to anthraquinone in 30% yield(4). Anthrone's estimated values for vapor pressure(5) and Henry's Law constant(6,SRC) indicate that volatilization from dry and moist soil surfaces is not likely to be a major fate process for this compound(SRC).
AQUATIC FATE: Based on a recommended classification scheme(1), an estimated Koc value of 2300(SRC), determined from a measured log Kow(2) and a recommended regression-derived equation(3), indicates that anthrone should adsorb to sediment and suspended solids(SRC). Anthrone may volatilize slowly from water surfaces based on an estimated Henry's Law constant of 7.9X10-7 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). Estimated half-lives for a model river and model lake are 65 and 480 days, respectively(3,SRC). An estimated BCF value of 360(3,SRC), from a measured log Kow(2), suggests that anthrone will bioconcentrate in aquatic organisms(SRC), according to a recommended classification scheme(5).
ATMOSPHERIC FATE: According to a suggested classification scheme(1), an estimated vapor pressure of 1.8X10-5 mm Hg at 25 deg C(2,SRC) indicates that anthrone will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase anthrone 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 40 hours(3,SRC). Particulate-phase anthrone may be physically removed from the air by dry deposition(SRC).
