FIFRA 요건As the federal pesticide law FIFRA directs, EPA is conducting a comprehensive review of older pesticides to consider their health and environmental effects and make decisions about their future use. Under this pesticide reregistration program, EPA examines health and safety data for pesticide active ingredients initially registered before November 1, 1984, and determines whether they are eligible for reregistration. In addition, all pesticides must meet the new safety standard of the Food Quality Protection Act of 1996. Pesticides for which EPA had not issued Registration Standards prior to the effective date of FIFRA '88 were divided into three lists based upon their potential for human exposure and other factors, with List B containing pesticides of greater concern and List D pesticides of less concern. Quinolinol is found on List D. Case No: 4047Case Status: No products containing the pesticide are actively registered. Therefore, we are characterizing the case as "cancelled." Under FIFRA, pesticide producers may voluntarily cancel their registered products. EPA also may cancel pesticide registrations if registrants fail to pay required fees or make/meet certain reregistration commitments, or if EPA reaches findings of unreasonable adverse effects.Active ingredient (AI): quinolinolAI Status: The active ingredient is no longer contained in any registered products. Thus, we characterize it as "cancelled."
Reactivity Profile8-HYDROXYQUINOLINE darkens on exposure to light. This chemical readily forms stable metal chelates. It is incompatible with strong oxidizers. It is also incompatible with many metal ions. (NTP, 1992)
Air and Water ReactionsInsoluble in water.
소화Fires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher. (NTP, 1992)
응급 처치EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.
비화재 누출 대응SMALL SPILLS AND LEAKAGE: Should a spill occur while you are handling this chemical, FIRST REMOVE ALL SOURCES OF IGNITION, then you should dampen the solid spill material with 60-70% ethanol and transfer the dampened material to a suitable container. Use absorbent paper dampened with 60-70% ethanol to pick up any remaining material. Seal the absorbent paper, and any of your clothes, which may be contaminated, in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with 60-70% ethanol followed by washing with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.
처리 방법SRP: 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.

상호 작용AFTER LETHAL IM DOSES IN MICE (30 MG/KG) INJECTED D-PENICILLAMINE (1 G/KG) PREVENTED /TOXIC/ SYMPTOMS & DEATH BUT NOT TRANSIENT HYPERGLYCEMIA.THE INFLUENCE OF RADIOPROTECTORS, CYSTEAMINE & AMINOETHYLISOTHIOURONIUM AS WELL AS OF THE AMINO ACIDS L-ALANINE, L-CYSTEINE, L-ARGININE, L-ASPARAGINE, L-GLUTAMIC ACID, L-HISTIDINE, & L-METHIONINE, ON THE CYTOGENETIC ACTION OF 8-HYDROXYQUINOLINE SULFATE WAS TESTED IN HUMAN LYMPHOCYTE CULTURES IN VITRO. EXCESS L-CYSTEINE, CYSTEAMINE, & L-ASPARAGINE ADDED SIMULTANEOUSLY WITH 8-HYDROXYQUINOLINE SULFATE DISTINCTLY REDUCED THE CHROMOSOME. DAMAGING EFFECT OF 8-HYDROXYQUINOLINE. L-GLUTAMIC ACID & AMINOETHYLISOTHIOURONIUM EXERTED LESSER PROTECTIVE ACTIVITY. L-METHIONINE DISPLAYED SOME EFFECT ONLY IN REDUCING THE RELATIVELY RARE ISOCHROMATID ABERRATIONS INDUCED BY 8-HYDROXYQUINOLINE SULFATE. THE OTHER AMINO ACIDS HAD NO EFFECT.The formation of DNA-strand breaks was studied in cultured human lung cells (A 549) subjected to iron, either in the form of iron(III) citrate or in combination with the metal chelators ethylene diamine tetra-acetic acid (EDTA), nitrilo triacetic acid (NTA), or 8-hydroxyquinoline (8HQ). After 15 min exposure to 5 uM iron(III) citrate or iron chelate, the cellular levels of iron were found to be three times higher in cells subjected to iron-8HQ than in cells subjected to iron(III) citrate, iron-EDTA or iron-NTA. Exposure to iron-8HQ caused extensive DNA-strand breakage, whereas no such breakage was found in cells exposed to iron-EDTA or iron-NTA. The DNA damage caused by iron-8HQ increased with time and dose, and DNA-strand breakage was clearly demonstrable in cells after 15 min exposure to as little as 0.1 uM iron-8HQ. Moreover, iron-8HQ was strongly toxic to the cells and inhibited their growth after exposure. Along with the formation of DNA-strand breaks, the concentration of cellular malondialdehyde increased four-fold after exposure to iron-8HQ and two-fold after exposure to iron-EDTA or iron-NTA, suggesting that reactive oxygen metabolites might be involved in the toxic action. Moreover, both iron-EDTA and iron-NTA caused a considerable hydroxylation of deoxyguanosine (dG) residues in DNA in vitro, whereas iron(III) citrate and iron-8HQ only caused a minor hydroxylation of dG. This points to the possibility that iron-8HQ-mediated DNA-strand breakage in cells might be due to the action of a metal-bound oxyl radical formed from the iron-8HQ complex rather than to the formation of hydroxyl radicals. Altogether, these findings indicate that iron bound to the lipophilic chelator, 8HQ, has strong toxic properties and that it may cause substantial DNA-strand breakage and lipid peroxidation in living cells.
환경 거동TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 3,000(SRC), determined from a structure estimation method(2), indicates that 8-hydroxyquinoline is expected to have slight mobility in soil(SRC). Volatilization of 8-hydroxyquinoline from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 5.7X10-7 atm-cu m/mole(SRC), based upon its vapor pressure, 1.66X10-3 mm Hg(3), and water solubility, 556 mg/l(4). 8-Hydroxyquinoline is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(3). Biodegradation in soil is not an important environmental fate process based on a 0% theoretical BOD using sewage sludge(5).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 3,000(SRC), determined from a structure estimation method(2), indicates that 8-hydroxyquinoline 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 5.7X10-7 atm-cu m/mole(SRC) derived from its vapor pressure, 1.66X10-3 mm Hg(4) and water solubility, 556 mg/l(5). According to a classification scheme(6), an estimated BCF of 7(SRC), from its log Kow of 2.02(7) and a regression-derived equation(8), suggests the potential for bioconcentration in aquatic organisms is low(SRC). To test for photolytic degradation in aqueous solution, 8-hydroxyquinoline was illuminated with filtered light, simulating daylight(9). The half-life for the photolytic degradation of 8-hydroxyquinoline ranged from 40-64 hours. Biodegradation in water is not an important environmental fate process based on a 0% theoretical BOD using sewage sledge(10).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 8-hydroxyquinoline, which has a vapor pressure of 1.66X10-3 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 8-hydroxyquinoline 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 2.0 hrs(SRC), calculated from its rate constant of 2.0X10-10 cu cm/molecule-sec at 25 °C(SRC) determined using a structure estimation method(3). 8-Hydroxyquinoline is expected to undergo photolysis in the atmosphere based upon aquatic photolytic experiments. The half-life for the photolytic degradation of 8-hydroxyquinoline in aqueous solution illuminated with filtered light, simulating daylight, ranged from 40-64 hours(4).
