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.

SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

A skin, eye irritant.

1-Chloroanthraquinone was detected in an extract of flyash from a municipal incinerator in Ontario, Canada at unreported concentrations(1).

WASTE WATERS FROM ALPHA-DISULFATION OF ANTHRAQUINONE, WHICH CONTAIN ANTHRAQUINONESULFONIC ACIDS, ARE TREATED TO FORM HALOANTHRAQUINONES.|1-Chloroanthraquinone's production and subsequent use as an intermediate in the production of dyes, including Disperse Red 9, Disperse Red 22, Vat Brown 1, Vat Brown 44, Vat Yellow 28(1), may result in its release to the environment through various waste streams(SRC).

TERRESTRIAL FATE: An estimated Koc value of 3500(1,SRC), based on an estimated log Kow of 3.99(2,SRC) suggests that 1-chloroanthraquinone will have only slight mobility in soil(SRC), based upon a recommended classification scheme(3). Under reducing conditions, this compound has been shown to form the chloroanthrone with measured half-lives of <0.4 to 2.4 daysin sediments(4) and this may also occur in soils(SRC). Incomplete information is available regarding the biodegradation potential of 1-chloroanthraquinone; however, this compound was resistant to biodegradation under aerobic conditions using an activated sludge inoculum; only 2.8% of the theoretical BOD was reported following 2 weeks incubation(5). 1-Chloroanthraquinone is not expected to volatilize from moist soil surfaces based on an estimated Henry's Law constant of 2.4X10-9 atm-cu m/mole(6,SRC).|AQUATIC FATE: Based upon an estimated Koc value of 3500(SRC) from an estimated log Kow(2,SRC), 1-chloroanthraquinone may adsorb to suspended solids and sediments(SRC) based upon a recommended classification scheme(1). In anoxic sediments, 1-chloroanthraquinone has been shown to quickly reduce resulting in the formation of an unspecified chloroanthrone(4). Half-lives of <0.4 to 2.4 days are reported for this compound dependent on the source of the sediment(4). An estimated BCF value of 630(3,SRC), based on an estimated log Kow(2,SRC) and measured BCF values of 118-351 in carp(5) indicate that 1-chloroanthraquinone may bioconcentrate in aquatic organisms(SRC). Incomplete information is available regarding the biodegradation potential of 1-chloroanthraquinone; however, this compound was resistant to biodegradation under aerobic conditions using an activated sludge inoculum; only 2.8% of theoretical BOD was reported following 2 weeks incubation(5). 1-Chloroanthraquinone is not expected to volatilize from water surfaces based on an estimated Henry's Law constant of 2.2X10-12 atm-cu m/mole(SRC), developed using a fragment constant method(6).|ATMOSPHERIC FATE: Based on an estimated vapor pressure value of 8.74X10-7 mm Hg at 25 °C(1,SRC), 1-chloroanthraquinone will exist in both the vapor phase and the particulate phase in the ambient atmosphere(2,SRC). 1-Chloroanthraquinone will degrade fairly rapidly in the vapor phase by reaction with photochemically produced hydroxyl radicals with an estimated half-life of about 13 days(3,SRC). Particulate phase 1-chloroanthraquinone may be physically removed from the air by wet and dry deposition(SRC).

The rate constant for the vapor phase reaction of 1-chloroanthraquinone with photochemically produced hydroxyl radicals has been estimated as 1.3X10-12 cu cm/molecule-sec at 25 °C(1). The half-life of 1-chloroanthraquinone is approximately 13 days based on a concentration of 5X10+5 hydroxyl radicals per cu cm(1,SRC). 1-Chloroanthraquinone, added to lake bottom sediments, resulted in the formation of a chlorine containing anthrone(2). 1-Chloroanthraquinone had measured first-order rate constants of 1.2X10-2 to 6.5X10-2/hr giving half-lives from <0.4 to 2.4 days for this anoxic sediment-water system(2).

199.53|Experimental BCF values of 118-351 were measured using carp(1). An estimated BCF value of 630 was calculated for 1-chloroanthraquinone(SRC), using an estimated log Kow of 3.99(2,SRC) and a recommended regression-derived equation(3). These BCF values suggest that 1-chloroanthraquinone may bioconcentrate in aquatic organisms(SRC).

Based on an estimated log Kow of 3.99(1,SRC), the Koc of 1-chloroanthraquinone is estimated as approximately 3500(SRC) using a regression-derived equation(2). According to a suggested classification scheme(3), this estimated Koc value suggests that 1-chloroanthraquinone will have only slight mobility in soil(SRC).

The Henry's Law constant for 1-chloroanthraquinone is estimated as 2.36X10-9 atm-cu m/mole(1,SRC). This indicates that 1-chloroanthraquinone will essentially not volatilize from water surfaces(2,SRC).

Quinones (ie, 6,12-dione) have been shown to undergo oxidation-reduction cycles involving quinone, hydroquinone, and molecular oxygen, resulting in the formation of oxygen radicals and semiquinone radicals. /Quinones/
