| 환경 거동 | TERRESTRIAL FATE: Cyclohexanone is estimated to be highly mobile in soil(1,3,SRC). In view of its moderate vapor pressure(2) and low adsorption to soil(3), it would be expected to volatilize from surface soil. Although data are lacking, it may also undergo direct photolysis on the soil surface(4). Cyclohexanone is readily biodegradable according to aerobic screening tests(5-12) and therefore would be expected to biodegrade in soil(SRC).AQUATIC FATE: If released in water, cyclohexanone would be slowly lost by volatilization. Its estimated half-lives in a model river and model lake are 4.1 and 33 days, respectively(1,2). Cyclohexanone is readily biodegradable according to aerobic screening tests(6) and in a die-away test performed using microorganisms from river water(3) and therefore, may be expected to biodegrade in natural waters. Adsorption to sediment(2,4) and bioconcentration(2,5) in aquatic organisms should be minimal(2) based upon its high water solubility(4) and low octanol/water partition coefficient(5).ATMOSPHERIC FATE: In the atmosphere, cyclohexanone will degrade by reacting with photochemically-produced hydroxyl radicals. Its estimated half-life resulting from this reaction is 1.3 days(1,2). |

| Effluent Concentrations | In a comprehensive survey of wastewater from 4,000 industrial and publicly owned treatment works (POTWs) sponsored by the Effluent Guidelines Division of the U.S. EPA, cyclohexanone was identified in discharges of the following industrial category (positive occurrences, median concentration in ppb): leather tanning (4593), iron and steel manufacturing (213.3), nonferrous metals (128.1), paint and ink (534.4), printing and publishing (2149), ore mining (23.1), inorganic chemicals (532.7), plastics and synthetics (2375.8), auto and other laundries (11.2), pharmaceuticals (244.2), explosives (116.8), aluminum (412.9), electronics (411.9), organic chemicals (262.7), and POTWs (1223.5)(1). Maximum effluent concentrations above 1000 ppb were observed in leather tanning (1,927 ppb), inorganic chemicals (10,256 ppb), and plastics and synthetics (2,345 ppb)(1).Wastewater from advanced treatment facilities in Lake Tahoe, CA, Dallas, TX, and Blue Plains, Washington, DC contained cyclohexanone(1). A final effluent grab sample from the Danville, IL POTW collected in June 1980 contained cyclohexanone(2). Wastewaters from processing shale oil have been found to contain cyclohexanone(3,4). It was identified in leachate from a municipal landfill in Ontario, Canada(5). The concentration of cyclohexanone in active compost blower exhaust from a wastewater sludge composting facility was 13 ug/cu m(6). |
| EPA IRIS Information | Cyclohexanone5 mg/kg-day |
| Medical Surveillance | Consider the points of attack /respiratory system, eyes, skin, central nervous system/ in preplacement and periodic physical examinations. |
| Soil Adsorption/Mobility | The Koc for cyclohexanone estimated using structure activity relationships (SAR) is 15(1). A Koc of 17 can be estimated from the water solubility, 23,000 mg/L(2), using a recommended regression equation(3). According to a suggested classification scheme(4), these Koc values indicate that cyclohexanone will be highly mobile in soil. |
| RCRA 요건 | U057As stipulated in 40 CFR 261.33, when CYCLOHEXANONE, as a commercial chemical product or manufacturing chemical intermediate or an off-specification commercial chemical product or a manufacturing chemical intermediate, becomes a waste, it must be managed according to Federal and/or State hazardous waste regulations. Also defined as a hazardous waste is any residue, contaminated soil, water, or other debris resulting from the cleanup of a spill, into water or on dry land, of this waste. Generators of small quantities of this waste may qualify for partial exclusion from hazardous waste regulations (40 CFR 261.5).When cyclohexanone is a spent solvent, it is classified as a hazardous waste from a nonspecific source (F003), as stated in 40 CFR 261.31, and must be managed according to State and/or Federal hazardous waste regulations. |
| TSCA 요건 | Section 8(a) of TSCA requires manufacturers of this chemical substance to report preliminary assessment information concerned with production, use, and exposure to EPA as cited in the preamble in 51 FR 41329.Pursuant to section 8(d) of TSCA, EPA promulgated a model Health and Safety Data Reporting Rule. The section 8(d) model rule requires manufacturers, importers, and processors of listed chemical substances and mixtures to submit to EPA copies and lists of unpublished health and safety studies. Cyclohexanone is included on this list. |
| FIFRA 요건 | As 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, as amended in 1988, 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. Cyclohexanone is found on List C. Case No: 3053Pesticide type: insecticideCase Status: No products containing the pesticide are actively registered ... The case /is characterized/ 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): CyclohexanoneAI Status: The active ingredient is no longer contained in any registered pesticide products ... "cancelled."Cyclohexanone is exempted from the requirement of a tolerance when used as a solvent or cosolvent in accordance with good agricultural practice as inert (or occasionally active) ingredients in pesticide formulations applied to growing crops only.Cyclohexanone is exempted from the requirement of a tolerance when used as a solvent or cosolvent accordance with good agricultural practice as inert (or occasionally active) ingredients in pesticide formulations applied to animals. |
| 대기 기준 | This action promulgates standards of performance for equipment leaks of Volatile Organic Compounds (VOC) in the Synthetic Organic Chemical Manufacturing Industry (SOCMI). These standards implement Section 111 of the Clean Air Act and are based on the Administrator's determination that emissions from the Synthetic Organic Chemical Manufacturing Industry cause, or contribute significantly to, air pollution which may reasonably be anticipated to endanger public health or welfare. The intended effect of these standards is to require all newly constructed, modified, and reconstructed Synthetic Organic Chemical Manaufacturing Industry process units to use the best demonstrated system of continuous emission reduction for equipment leaks of Volatile Organic Compounds, considering costs, non air quality health and environmental impact and energy requirements. Cyclohexanone is produced, as an intermediate or final product, by process units covered under this subpart. These standards of performance become effective upon promulgation but apply to affected facilities for which construction or modification commenced after January 5, 1981. |

Cyclohexanone, a colorless liquid is a cyclic ketone. It is an important building block for the synthesis of a variety of organic compounds. Majority of the cyclohexanone synthesized is utilized as an intermediate in the synthesis of nylon.Used as a polyvinyl chloride (PVC) solvent, cyclohexanone caused contact dermatitis in a woman manufacturing PVC fluidotherapy bags. Cyclohexanone probably does not cross react with cyclohexanone resin. A cyclohexanone-derived resin used in paints and varnishes caused contact dermatitis in painters.
