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.

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 2,000(SRC), determined from a log Kow of 3.52(2) and a regression-derived equation(3), indicates that 1-hydroxyanthraquinone is expected to have slight mobility in soil(SRC). Volatilization of 1-hydroxyanthraquinone from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 7.2X10-9 atm-cu m/mole(SRC), derived from its vapor pressure, 2.09X10-7 mm Hg(4), and water solubility, 8.5 mg/l(5). 1-Hydroxyanthraquinone is not expected to volatilize from dry soil surfaces(SRC) based upon it's vapor pressure(4). Biodegradation in soil is not expected to be an important environmental fate process based on a 1-5% theoretical BOD using activated sludge and the Japanese MITI test(6).

AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 2,000(SRC), determined from a log Kow of 3.52(2) and a regression-derived equation(3), indicates that 1-hydroxyanthraquinone is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(3) based upon an estimated Henry's Law constant of 7.2X10-9 atm-cu m/mole(SRC), derived from its vapor pressure, 2.09X10-7 mm Hg(4), and water solubility, 8.5 mg/l(5). According to a classification scheme(6), BCFs ranging from 55-318(7), suggest the potential for bioconcentration in aquatic organisms is moderate to high(SRC). Biodegradation in water is not expected to be an important environmental fate process based on a 1-5% theoretical BOD using activated sludge and the Japanese MITI test(8). However, in most anoxic sediments, uncharged simple anthraquinone dyes exhibit half-lives of less than 10 days(8).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 1-hydroxyanthraquinone, which has a vapor pressure of 2.09X10-7 mm Hg at 25 °C(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase 1-hydroxyanthraquinone 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 28 hrs(SRC), calculated from its rate constant of 1.4X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Particulate-phase 1-hydroxyanthraquinone may be removed from the air by wet and dry deposition(SRC). 1-Hydroxyanthraquinone isomers photodecomposed under irradiation with visible light in aerated alkaline solution, with phthalic acid as the main product(4).

Occupational hepatotoxin - Secondary hepatotoxins: the potential for toxic effect in the occupational setting is based on cases of poisoning by human ingestion or animal experimentation.；IARC Carcinogen - Class 3: Chemicals are not classifiable by the International Agency for Research on Cancer.

PRECAUTIONS FOR "CARCINOGENS": Whenever medical surveillance is indicated, in particular when exposure to a carcinogen has occurred, ad hoc decisions should be taken concerning ... /cytogenetic and/or other/ tests that might become useful or mandatory. /Chemical Carcinogens/

The Koc of 1-hydroxyanthraquinone is estimated as 2,000(SRC), using a log Kow of 3.52(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 1-hydroxyanthraquinone is expected to have slight mobility in soil.

AEROBIC: 1-Hydroxyanthraquinone, present at 100 mg/l, reached 1-5% of its theoretical BOD in four weeks using an activated sludge inoculum at 20 mg/l and the Japanese MITI test(1).

BCF ranges of 55-318 and 62-297 at test chemical concns of 50 and 5 mg/l, respectively, were measured for 1-hydroxyanthraquinone using orange-red killifish (Oryzias latipes) which were exposed over an 8-week period(1). According to a classification scheme(2), BCF values of 30 to 100 are moderate and from 100 to 1,000 are high.

The Henry's Law constant for 1-hydroxyanthraquinone is estimated as 7.25X10-9 atm-cu m/mole(SRC) derived from its vapor pressure, 2.09X10-7 mm Hg(1), and water solubility, 8.5 mg/l(2). This Henry's Law constant indicates that 1-hydroxyanthraquinone is expected to be essentially nonvolatile from water surfaces(3). 1-Hydroxyanthraquinone is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(1).

/LABORATORY ANIMALS: Subchronic or Prechronic Exposure/ 1-Hydroxyanthraquinone was fed in the diet (0.5%, 1%, 2% 4%) to male Fischer 344 rats for seven days. Induction of cell proliferation in the intestines was analysed by BrdU labelling. At the high dose, 1-hydroxyanthraquinone induced cell proliferation in the cecum and the proximal colorectum, but there was little evidence of intestinal cytotoxicity.

/LABORATORY ANIMALS: Chronic Exposure or Carcinogenicity/ A group of 30 male ACI/N rats, 1.5 months of age, was fed 1% 1-hydroxyanthraquinone in CE-2 diet throughout the experimental period of 480 days. Thirty control rats were fed basal diet. Rats that survived more than 280 days developed various tumors of the intestine (25/29). These comprised cecal adenomas (10/29) or adenocarcinomas (5/29) and colonic adenomas (12/29) or adenocarcinomas (11/29). No such tumors were diagnosed in control rats. In addition, neoplastic nodules and hepatocellular adenomas (12/29) and forestomach papillomas and glandular stomach adenomas (5/29) were observed. No such tumors were observed in control animals.

/LABORATORY ANIMALS: Chronic Exposure or Carcinogenicity/ A group of 27 male ACI/N rats, six weeks of age, was fed 1.5% 1-hydroxyanthraquinone in the diet for 48 weeks. A second group (14 rats) was also given 16 mg/l indomethacin in the drinking water for the experimental period. Fifteen control rats were fed basal diet. Rats fed with 1-hydroxyanthraquinone had incidences of 12/27 large intestinal neoplasms (adenomas and adenocarcinomas) and 14/27 forestomach tumors (papillomas). In rats fed 1-hydroxyanthraquinone and treated with indomethacin, these incidences were 0/14 and 2/14 respectively. Untreated animals and rats given indomethacin alone had no neoplasms in the large intestine and forestomach.

/LABORATORY ANIMALS: Chronic Exposure or Carcinogenicity/ A group of ACI/N rats fed 1/5% 1-hydroxyanthraquinone in the diet for 48 weeks showed inflammatory changes of various degrees (colitis, ulcerative colitis or melanosis coli) in the large bowel, but no clinical sign of toxicity.

Evaluation: There is inadequate evidence in humans for the carcinogenicity of laxatives containing anthraquinone derivatives. There is sufficient evidence in experimental animals for the carcinogenicity of 1-hydroxyanthraquinone. Overall evaluation: 1-Hydroxyanthraquinone is possibly carcinogenic to humans (Group 2B).

... 1-Hydroxyanthraquinone was found to be absorbed when continuously administered to rats (strain not specified) by stomach tube (50 mg suspended in aqueous gum arabic), and its metabolites were identified by paper chromatography. Urine and feces were collected during 48 hours after treatment and extracted with diethyl ether. Of the 1-hydroxyanthraquinone originally present, 2.49% and 0.74% were converted into alizarin (1,2-dihydroxyanthraquinone), in urine and feces, respectively. The alizarin was then excreted after sulfation and glucuronidation.

1-Hydroxyanthraquinone can be used as an intermediate in the production of dyes and drugs.

A general method for synthesis of anthraquinones, including 1-hydroxy-anthraquinone, has been developed. The anthraquinones were obtained under mild conditions from ortho-dicarboxylic acid chlorides and suitable aromatic substrates via a FriedelCrafts process.

1-Hydroxyanthraquinone has been synthesized by diazotization of 1-aminoanthraquinone and heating the diazonium salt with concentrated sulfuric acid. After dilution with water, the precipitated crude product was diluted with acetone and purified by preparative thin-layer chromatography (TLC) in toluene:ethyl formate:formic acid (75:24:1).

1-Hydroxyanthraquinone has also been prepared in 96.4% yield by reacting 1-nitroanthraquinone with sodium formate in dimethylformamide at 130 C for 17 hours.
