SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

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 °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).

Several unspecified isomers of anthrone were detected in chlorinated coal-tar leachate at unreported concentrations(1). A heavy-duty diesel exhaust particulate sample, NBS SRM 1650, contained anthrone at unreported concentrations(2). Diesel emission particulates, collected from a Volkswagen Rabbit contained anthrone(3). Fine particle emissions from the combined exhaust of a vented natural gas-fired residential space heater plus a water heater contained 21.4 pg/kJ anthrone(4).

The Koc of anthrone is estimated as approximately 2300(SRC), using a measured log Kow of 3.66(1) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that anthrone has only slight mobility in soil(SRC).

Superficial marine sediments of Cortiou Creek, in the sewage area of Marseilles, France, are contaminated with anthrone at concentrations ranging from non-detectable to 300 ng/g (9 of 10 sites had measurable quantities of anthrone; detection limit not given)(1).

An estimated BCF value of 360 was calculated for anthrone(SRC), using a measured log Kow of 3.66(1) and a recommended regression-derived equation(2). According to a recommended classification scheme(3), this BCF value suggests that bioconcentration in aquatic organisms will be an important fate process(SRC).

The Henry's Law constant for anthrone is estimated as 7.9X10-7 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This value indicates that anthrone will slowly volatilize from water surfaces(2,SRC). 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) is estimated as approximately 65 days(2,SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec) is estimated as approximately 480 days(2,SRC). Anthrone's values for vapor pressure(3) and Henry's Law constant(1,SRC) indicate that volatilization from dry and moist soil surfaces is not likely to be a major fate process for this compound(SRC).

The rate constant for the vapor-phase reaction of anthrone with photochemically produced hydroxyl radicals has been estimated as 9.8X10-12 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1,SRC). This corresponds to an atmospheric half-life of about 40 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1,SRC).
