The following Overview, *** ANTHRAQUINONES ***, is relevant for this HSDB record chemical. Life Support: o This overview assumes that basic life support measures have been instituted. Clinical Effects: 0.2.1 SUMMARY OF EXPOSURE 0.2.1.1 ACUTE EXPOSURE A) These agents have an irritant cathartic action. Most human cases are mild to moderate in severity, with nausea, vomiting, diarrhea, abdominal cramps, and palpitations as the primary symptoms. Severe poisonings may produce kidney damage, gastrointestinal hemorrhage, muscular seizures, dyspnea, and fluid depletion. B) PLANT MATERIAL - There is a 6-hour delay in onset with commercial cascara sagrada preparations that is not seen in intoxications from fresh plant material, due to other active ingredients in the plants. 1) Vomiting is also more prevalent with fresh plant material. 0.2.4 HEENT 0.2.4.1 ACUTE EXPOSURE A) DITHRANOL is an irritant to the eyes and mucous membranes. 0.2.5 CARDIOVASCULAR 0.2.5.1 ACUTE EXPOSURE A) Palpitations were seen in one case report of 6 women who became toxic after ingesting an anthraquinone-containing herbal tea. 0.2.6 RESPIRATORY 0.2.6.1 ACUTE EXPOSURE A) Dyspnea is mentioned as a sign of severe poisoning. 0.2.7 NEUROLOGIC 0.2.7.1 ACUTE EXPOSURE A) Muscular seizures are a rare sign of severe intoxication. Dizziness is occasionally seen in severe intoxications. CNS depression was seen in animals tested with injections of emodin. Analgesia was also noted with injection. These effects have not been noted in human overdose. 0.2.8 GASTROINTESTINAL 0.2.8.1 ACUTE EXPOSURE A) Nausea, vomiting, abdominal pain, and especially diarrhea may be seen with both therapeutic doses and overdose. 0.2.10 GENITOURINARY 0.2.10.1 ACUTE EXPOSURE A) Oliguria and proteinuria may be seen in severe cases. A red color is seen in alkaline urine, and yellow-brown in acid urine. Large doses of anthraquinones may cause nephritis. 0.2.12 FLUID-ELECTROLYTE 0.2.12.1 ACUTE EXPOSURE A) If vomiting and diarrhea are extensive, excessive fluids and electrolytes may be lost. 0.2.14 DERMATOLOGIC 0.2.14.1 ACUTE EXPOSURE A) Some anthraquinones have been shown to be sensitizers. Finger CLUBBING has been reported with abuse of senna. The condition is reversible with discontinuation of the drug. Dithranol may cause a burning sensation, especially on perilesional skin. 0.2.20 REPRODUCTIVE HAZARDS A) Casanthranol, danthron, senna, and cascara sagrada are in pregnancy category C. 0.2.21 CARCINOGENICITY 0.2.21.2 HUMAN OVERVIEW A) Various anthraquinones have been shown to have carcinogenic potential. 0.2.22 GENOTOXICITY A) Various anthraquinones have been shown to have mutagenic potential. Many are frameshift mutagens. Laboratory: A) In cases where diarrhea and vomiting have been excessive, fluid and electrolyte abnormalities might be seen. In such cases monitor for electrolyte loss and/or dehydration. B) A red color is seen in alkaline urine, which turns a yellow-brown in acid urine. The red urine should be differentiated from hematuria. Treatment Overview: 0.4.2 ORAL EXPOSURE A) Emesis is not required. Since not all of the cathartic would be removed with an emetic, vomiting and diarrhea may be seen with overdose. Activated charcoal (without cathartic) may be indicated. B) GASTRIC LAVAGE: Consider after ingestion of a potentially life-threatening amount of poison if it can be performed soon after ingestion (generally within 1 hour). Protect airway by placement in Trendelenburg and left lateral decubitus position or by endotracheal intubation. Control any seizures first. 1) CONTRAINDICATIONS: Loss of airway protective reflexes or decreased level of consciousness in unintubated patients; following ingestion of corrosives; hydrocarbons (high aspiration potential); patients at risk of hemorrhage or gastrointestinal perforation; and trivial or non-toxic ingestion. C) ACTIVATED CHARCOAL: Administer charcoal as a slurry (240 mL water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents, 25 to 50 g in children (1 to 12 years), and 1 g/kg in infants less than 1 year old. 0.4.4 EYE EXPOSURE A) DECONTAMINATION: Irrigate exposed eyes with copious amounts of room temperature water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility. 0.4.5 DERMAL EXPOSURE A) OVERVIEW 1) DECONTAMINATION: Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician may need to examine the area if irritation or pain persists. Range of Toxicity: A) Deaths of a 3-year-old and a 20-month-old after ingestion of an unknown number of Rhamnus berries have been reported. B) Rhamnus fruits - In reports to Toxicology Centers throughout Europe, there are exposures reported, but none have resulted in serious symptoms. C) Rheum species - Determination of a toxic dose is very difficult when dealing with plant material. Various species have different concentrations of anthraquinones.

New York: Marcel Dekker, Inc., 1971. 9]**PEER REVIEWED** Pharmacology: Environmental Fate & Exposure: Environmental Fate/Exposure Summary: Anthraquinone's production and subsequent use as an additive in the paper pulping industry,as a bird repellent for seeds, and as the basis for the production of a large number of dyes may result in its release to the environment through various waste streams. Anthraquinone is also produced from anthracene in the environment through photolytic and biodegradation processes. If released to the atmosphere, anthraquinone will exist in both the vapor-phase and the particulate phase based on an experimental vapor pressure of 1.16X10-7 mm Hg. In the vapor-phase, it should react with hydroxyl radicals with an estimated half-life of 11 days. Particulate phase anthraquinone may be physically removed from air by wet and dry deposition. Anthraquinone should have slight to low mobility in soil based on estimated Koc values of 1664 and 3702. This compound is expected to biodegrade fairly rapidly with 68% degradation reported in 12 weeks by a mixed soil population. In water, anthraquinone is expected to adsorb to particulate matter and sediment in the water column based on its Koc values. Biodegradation is a major fate process in water; over a three day period, 82% of the added anthraquinone (at 10 mg/L) was degraded by river water, 91% was degraded by sea water. Anthraquinone is also readily biodegraded by natural bacterial populations in groundwater and by activated sludge. A photolysis half-life of 2.8 hours was measured when anthraquinone was exposed to incident light (295-500 nm). Anthraquinone may bioconcentrate in aquatic organisms based on estimated BCF values of 222 and 522; this compound has been detected in fish. Monitoring data indicate that exposure to anthraquinone by the general population is through the ingestion of drinking water. Exposure to anthraquinone may occur occupationally during its use as a dye intermediate or as a catalytic agent in the paperpulping process. (SRC) **PEER REVIEWED** Probable Routes of Human Exposure: Anthraquinone was detected in air samples collected in the potroom of an aluminum reduction plant at 297 ng/cu m(1). NIOSH (NOES Survey 1981-1983) has statistically estimated that 6188 workers (1603 of these are female) are potentially exposed to anthraquinone in the USA(2). [(1) Thrane KE, Stray H; Sci Total Environ 53: 111-31 (1986) (2) NIOSH; National Occupational Exposure Survey (NOES) (1983)]**PEER REVIEWED** Artificial Pollution Sources: Anthraquinone's production and subsequent use as an additive in the soda and kraft chemical alkaline pulping processes in the paper pulping industry(1) and as the basis for the production of a large number of acid and base dyes, vat dyes, disperse dyes, and reactive dyes(2) may result in its release to the environment through various waste streams(SRC). Anthracene, which is frequently detected in the environment probably due to its pyrogenic origin, is known to yield anthraquinone upon direct photooxidation in aqueous media(3). The biodegradation of anthracene by white rot fungi results in anthraquinone as a major degradation intermediate(4). Soil samples contaminated with diesel oil and originally not containing anthraquinone were found to contain anthraquinone following 25 weeks(5). Aqueous chlorination products of standard PAH's include anthraquinone; this process works via oxidation of the PAH using hypochlorite(6).

Anthraquinone is not expected to volatilize from dry surfaces based on an experimental vapor pressure of 1.16X10-7 mm Hg(5) or to volatilize from moist soil surfaces given an estimated Henry's Law constant of 3.18X10-9 atm-cu/mole(1,SRC) from the water solubility(3) and vapor pressure(5). Biodegradation of anthraquinone is expected to be a major fate process for this compound in soil; 68% of added anthraquinone was biodegraded by a mixed soil population within 12 weeks(6). A mixed bacterial population, isolated from a coal-tar contaminated soil, biodegraded anthraquinone even faster with only 6.5% of the initial concentration of anthraquinone remaining after 3 days(7).

Anthraquinone subjected to exhaustive photolysis (16 hr, 253.7 nm irradiation, in ethanol) undergoes photochemical conversion to 9,10-dihydroxyanthracene and secondly to 9-anthranol in the absence of oxygen(2). Anthraquinone deposited on silica gel and exposed in the dark did not react to the presence of ozone at varying concentrations and exposure times(3).
