All estimates of acceptable Intakes and carcinogenic potency presented 1n this document should be considered as preliminary and reflect limited resources allocated to this project. Pertinent toxlcologlc and environmental data were located through on-line literature searches of the Chemical Abstracts, TOXLINE, CANCERLINE and the CHEMFATE/DATALOG data bases. The basic literature searched supporting this document 1s current up to September, 1984. Secondary sources of Information have also been relied upon 1n the preparation of this report and represent large-scale health assessment efforts that entail extensive peer and Agency review. The following Office of Health and Environmental Assessment (OHEA) sources have been extensively utilized: U.S. EPA. 1981. Criteria Document for Acetone. Environmental Criteria and Assessment Office, Cincinnati, OH. Internal Draft. U.S. EPA. 1983b. Disposition of Comments on Criteria Document for Acetone. Environmental Criteria and Assessment Office, Cincinnati, OH. Internal Draft. The Intent In these assessments 1s to suggest acceptable exposure levels whenever sufficient data were available. Values were not derived or larger. uncertainty factors were employed when the variable data were limited 1n scope tending to generate conservative (I.e., protective) estimates. Never- theless, the Interim values presented reflect the relative degree of hazard associated with exposure or risk to the chemlcal(s) addressed. Whenever possible, two categories of values have been estimated for sys- temic toxicants (toxicants for which cancer 1s not the endpolnt of concern). The first, the AIS or acceptable Intake subchronlc, 1s an estimate of an exposure level that would not be expected to cause adverse effects when exposure occurs during a limited time Interval (I.e., for an Interval that does not constitute a significant portion of the Hfespan). This type of exposure estimate has not been extensively used or rigorously defined, as previous risk assessment efforts have been primarily directed towards exposures from toxicants 1n ambient air or water where lifetime exposure 1s assumed. Animal data used for AIS estimates generally Include exposures with durations of 30-90 days. Subchronlc human data are rarely available. Reported exposures are usually from chronic occupational exposure situations or from reports of acute accidental exposure. The AIC, acceptable Intake chronic, 1s similar In concept to the ADI (acceptable dally Intake). It Is an estimate of an exposure level that would not be expected to cause adverse effects when exposure occurs for a significant portion of the Hfespan [see U.S. EPA (1980) for a discussion of this concept]. The AIC 1s route specific and estimates acceptable exposure for a given route with the Implicit assumption that exposure by other routes 1s Insignificant. 111 ------- Composite scores (CSs) for noncardnogens have also been calculated where data permitted. These values are used for ranking reportable quanti- ties; the methodology for their development 1s explained 1n U.S. EPA (1983b). For compounds for which there 1s sufficient evidence of carclnogenlclty, AIS and AIC values are not derived. For a discussion of risk assessment methodology for carcinogens refer to U.S. EPA (1980). Since cancer 1s a process that 1s not characterized by a threshold, any exposure contributes an Increment of risk. Consequently, derivation of AIS and AIC values would be Inappropriate. For carcinogens, q-|*s have been computed based on oral and Inhalation data 1f available. 1v ------- ABSTRACT In order to place the risk assessment evaluation 1n proper context, refer to the preface of this document. The preface outlines limitations applicable to all documents of this series as well as the appropriate Inter- pretation and use of the quantitative estimates presented. The AIC for acetone, 209.6 mg/day, 1s based on a subchronlc (8-week) animal exposure study showing reversible changes following exposure to 19,000 ppm acetone. Although data are extremely limited, fragmentary human data at similar exposure concentrations Indicate no adverse effects. In addition, this AIC 1s below that which could be calculated from the most conservative occupational exposure guidelines (NIOSH, 1978). This estimate may be conservative and reflects the limited data base. Data were Inade- quate to estimate an AIS or AIC for oral exposure and were also Insufficient for derivation of a CS. ------- ACKNOWLEDGEMENTS The Initial draft of this report was prepared by Syracuse Research Corporation under Contract No. 68-03-3112 for EPA's Environmental Criteria and Assessment Office, Cincinnati, OH.

ENVIRONMENTAL CHEMISTRY AND FATE The relevant physical and chemical properties and environmental fate of acetone (CAS No. 67-64-1} are as follows: Molecular weight: Chemical class: Vapor pressure: Water solubility: Log octanol/water partition coefficient; BCF: Half-lives 1n A1r: Water: 58.08 aliphatic ketone 185.95 mm Hg at 20°C mlsdble with water -0.24 0.69 1n haddock muscle (Melanoqrammus aeglef1nus) 0.12 (estimated) 14 hours 10 hours to 9 days U.S. EPA, 1981 U.S. EPA, 1981 U.S. EPA, 1981 U.S. EPA, 1981 Graedel, 1978 U.S. EPA, 1981 The BCF value of 0.12 has been estimated from the equation of Veith et al. (1979) and the log octanol/water partition coefficient given above. The value for the half-life of acetone In the atmosphere 1s based on Its photochemical reaction and the rate constant for the photochemical reaction given by Graedel (1978). The half-life of acetone 1n water 1s based on Its evaporation rate from quiescent to different aerated conditions. The bio- degradation half-life may be comparable to Its evaporation half-life under certain conditions; however, blodegradatlon has not been considered In estimating the aquatic half-life of acetone because of the lack of available rate constant data. -1- ------- The half-life of acetone 1n soil could not be located In the literature searched; however, evaporation 1s expected to be the predominant loss mecha- nism from the soil surface. By analogy with the blodegradatlon studies of acetone 1n other media (U.S. EPA, 1981), It Is likely that It will undergo significant blodegradatlon 1n soils as well. The undecomposed acetone Is expected to leach from soil because of Its high water solubility and expected weak sorptlon on soils. The detection of acetone in both soil leachate and groundwater 1s evidence for Us soil Teachability (U.S. EPA, 1981). -2- ------- 2. ABSORPTION FACTORS IN HUMANS AND EXPERIMENTAL ANIMALS 2.1. ORAL Although absorption factors were not reported, several studies Indicate that acetone 1s readily absorbed through the gastrointestinal tract 1n humans and animals. Schwartz (1898) administered acetone either orally or subcutaneously to dogs. For both routes of exposure, 59-76% of the administered dose was eliminated through expired air, while 1.5-4.7% was excreted 1n the urine. Haggard et al. (1944), Parmegg1an1 and Sassl (1954), and Price and RHtenberg (1950) also reported that orally administered acetone was elimi- nated through expired air and in the urine. 2.2. INHALATION Numerous reports Indicate that acetone is absorbed through the pulmonary route of exposure. Dalhamn et al. (1968) demonstrated that 60% of the Inhaled dose of acetone (~1 mg in cigarette smoke) was absorbed by. humans within 2 seconds of contact. Haggard et al. (1944) reported that the absorption of acetone through inhalation in rats is rapid and dose-related, reaching steady-state after 2 days of continuous exposure. Similar results were obtained with volunteers; however, steady-state was not achieved because these Individuals were exposed for only 8 hours. Furthermore, greater absorption of acetone was observed 1n the volunteers who exercised during Inhalation. In an experiment similar to that of Haggard et al. (1944), DIVIncenzo et al. (1973) determined that light exercise (a cycle of jogging for 5 minutes followed by 10 minutes of rest) approximately doubled the postexposure levels of acetone in the expired breath of volunteers. Wlgaeus et al. -3- ------- (1981) also reported that the absorption of acetone through Inhalation In volunteers Increased with exercise, but added further that the relative uptake (39-52%) was not affected by the workload. -4- ------- 3. TOXICITY IN HUMANS AND EXPERIMENTAL ANIMALS 3.1. SUBCHRONIC 3.1.1. Oral. Very little Information regarding the subchronlc toxldty of orally administered acetone was located 1n the available literature. Sollman (1921) exposed three rats to 2.5% acetone In drinking water for 18 weeks. Upon termination of the experiment, the animals were found to be "practically normal," experiencing only weight loss, which might have been due to decreased food consumption. No other endpolnts were examined or reported. 3.1.2. Inhalation. Information regarding the subchronlc toxldty of Inhaled acetone Is also limited. Bruckner and Peterson (1981) exposed rats to vapors of acetone at levels of either 0 or 19,000 ppm for 3 hours/day, 5 days/week for 8 weeks. Groups of four rats were killed and examined at 2, 4 and 8 weeks throughout exposure and at 2 weeks postexposure. Narcosis was seen 1n animals exposed to acetone. These animals, however, had no changes 1n clinical chemistry variables or hlstologlcal changes 1n the liver, brain, kidneys, lungs or heart regardless of when they were examined. Slight decreases 1n organ weights and body weights were observed In rats killed during exposure but not 1n rats killed 2 weeks postexposure. 3.2. CHRONIC 3.2.1. Oral. Pertinent data regarding the chronic toxldty of orally administered acetone were not located 1n the available literature. 3.2.2. Inhalation. In two other occupational exposure studies, workers exposed to vapors of acetone at either 19-920 ppm (Parmegglanl and Sassl, 1954) or >750 ppm (Raleigh and McGee, 1972) complained of Irritation of the mucosal membranes, Including conjunctivitis, pharyngitis, Inflammatory bronchitis and gastroduodenltls. -5- ------- Oglesby et al. (1949) examined the physical condition, and hematologlcal and urologlcal variables 1n 800 men exposed occupatlonally to vapors of acetone (600-2150 ppm). These men were examined once a year from 1931 to 1948. There were no statistically significant differences between these men and a group of 800 controls with respect to any of the variables measured, though transient eye and nose irritation was experienced by some of the exposed workers. This study Indicates that exposure to <2150 ppm acetone for <8 hours/day produces no significant toxic effects. 3.3. TERATOGENICITY AND OTHER REPRODUCTIVE EFFECTS 3.3.1. Oral. Pertinent data regarding the teratogenlcity of Ingested acetone were not located in the available literature; however, acetone 1s known to cross the placenta (Dowty et al., 1975). 3.3.2. Inhalation. Pertinent data regarding the teratogenlcity of Inhaled acetone were not located in the available literature. 3.4. TOXICANT INTERACTIONS A number of studies indicate that acetone potentiates the hepatotoxlc effects of carbon tetrachloride (Tralger and Plaa, 1973; Plaa et al., 1975, 1982; Folland et al., 1976), 1,1,2-tr1chloroethane and 1,1 ,l-tr1chloroethane (Tralger and Plaa, 1973; Plaa et al., 1975; MacDonald et al., 1982), and Br-CHCl and trichloroethane (Hewitt et al., 1983). Acetone was also reported to antagonize semicarbaz1de-1nduced convulsions 1n rats (Kohli et al., 1967), but had an additive effect upon LD™ In rats treated with acetonltrile (Smyth et al., 1962). Glatt et al. (1981) reported that acetone enhanced the mutagenic activity of dlmethylnitrosamine 1n Iji vitro assays but not J_n vivo assays. -6- ------- 4. CARCINOGENICITY 4.1. HUMAN DATA 4.1.1. Oral. Pertinent data regarding the cardnogenlcHy of Ingested acetone were not located In the available literature. 4.1.2. Inhalation. Pertinent data regarding the cardnogenlcHy of Inhaled acetone were not located 1n the available literature. 4.2. BIOASSAYS 4.2.1. Oral. Pertinent data regarding the cardnogenlcHy of orally administered acetone were not located 1n the available literature. 4.2.2. Inhalation. Pertinent data regarding the cardnogenlcHy of Inhaled acetone were not located 1n the available literature. 4.3. OTHER RELEVANT DATA Acetone did not show mutagenlc activity when tested 1n microblal assay systems (McCann et a!., 1975; Abbondandolo et a!., 1980; Maron et al., 1981; Haellstrom et al., 1981) or 1n cell transformation systems (Freeman et al., 1973; Rh1m et al., 1974; Quarles et al., 1979a,b). Furthermore, acetone gave negative results In assays that tested for chromosomal aberrations and sister chromatld exchange (Norppa et al., 1981; Norppa, 1981; Tates and KMek, 1981), DNA cell binding (Kublnskl et al., 1981), point mutation 1n mouse lymphoma cells (Amacher et al., 1980) and transfectlon (Vasavada and Padayatty, 1981). In one study, however, acetone was reported to produce chomosomal aberrations but not sister chromatld exchange (Kawachl et al., 1980). 4.4. WEIGHT OF EVIDENCE Pertinent data regarding the cardnogenlcHy of acetone In humans or 1n experimental animals were not located 1n the available literature. The evidence for the cardnogenlcHy of acetone In humans 1s appropriately -7- ------- designated as Inadequate. Using the scheme for the classification of the cardnogenlcHy of chemicals to humans proposed by the Carcinogenic Assess- ment Group of the U.S. EPA (Federal Register, 1984), acetone is most appro- priately designated a Class D - Not Classified chemical. -8- ------- 5. REGULATORY STANDARDS AND CRITERIA ACGIH (1983) has recommended a TLV-TWA of 750 ppm and a STEL of 1000 ppm for occupational exposure to acetone. These values were chosen to prevent nose and eye Irritation (ACGIH, 1980). NIOSH (1978) has recommended a criterion of 250 ppm for exposure to acetone 1n the workplace, while OSHA has adopted 1000 ppm as a standard for occupational exposure to acetone (Code of Federal Regulations, 1981). -9- ------- 6. RISK ASSESSMENT 6.1. ACCEPTABLE INTAKE SUBCHRONIC (AIS) 6.1.1. Oral. The only subchronlc oral study located 1n the available literature was that of Sollman (1921). Data from this study cannot be used to derive an AIS or a CS because small numbers of animals were used; there was only one level of exposure; and hlstologlcal endpolnts were not examined and control animals were not maintained. 6.1.2. Inhalation. Bruckner and Peterson (1981) reported that rats experienced narcosis during the 3-hour exposure periods to 19,000 ppm acetone. In addition, body weight was slightly decreased 1n rats during the 8 weeks of treatment; however, body weight returned to control values by 2 weeks after cessation of exposure (Bruckner and Peterson, 1981). A NOAEL of 19,000 ppm can be established on the basis of reversible changes In organ and body weights 1n rats. Using the- NOAEL of 19,000 ppm (45,134 mg/m3), the animal dose 1n mg/kg/day can be calculated by assuming a rat breathes 0.26 mVday and weighs 0.35 kg, and by expanding the exposure from a 3-hour, 5 days/week Intermittent exposure to a continuous exposure as follows: mg/kg/day = 45,134 mg/m3 x 0.26 mVday x 3/24 x 5/7 * 0.35 kg = 2994 mg/kg/day To calculate the AIS, this animal dose Is multiplied by the assumed average human body weight of 70 kg and divided by an uncertainty factor of 100 (a factor 10 for converting an animal NOAEL to a human NOAEL and another factor of 10 to protect the more sensitive Individuals of a population). The AIS thus derived for acetone Is 2096 mg/day. -10- ------- Although exposure duration was only 3 hours/day, the extrapolation to a 24-hour day, 7 days/week exposure actually reduced the exposure concentra- tion by more than a factor of 10 before uncertainty factors were applied. The extrapolation 1s acceptable because this compound does not accumulate In tissues, Including fat, and H 1s rapidly excreted In expired air and 1n urine. Furthermore, there appear to be no major systemic effects other than narcosis even at unusually high exposure levels. The estimate of an AIS for Inhalation 1n mg/kg Implicitly assumes that the exposure will be spread uniformly over a day. 6.2. ACCEPTABLE INTAKE CHRONIC (AIC) 6.2.1. Oral. Data are Insufficient to calculate an AIC for chronic oral 1ngest1on of acetone. Data from which a CS for oral exposure to acetone can be calculated have not been located 1n the available literature. 6.2.2. Inhalation. The study by Oglesby et al. (1949) suggested a NOAEL at <21,500 ppm for workers exposed to acetone, but the lack of properly matched controls and uncertainties about levels of exposure preclude the use of this study 1n quantitative risk assessment. An Interim chronic Inhalation AOI can be derived from the Interim sub- chronic Inhalation ADI of 2096 mg/day by applying an additional uncertainty factor of 10 to convert subchronlc to chronic exposure. This results 1n an AIC of 209.6 mg/day for a 70 kg human. This estimate 1s 1n the same range, but more conservative than an estimate that could be derived using the most conservative criterion for occupational exposure [NIOSH, 1978 (250 ppm)]. The estimate of an AIC for Inhalation In units of mg/day Implicitly assumes that the exposure will be uniformly spread over the day. Data from which a CS for Inhalation exposure to acetone can be calculated have not been located 1n the available literature. -11- ------- 6.3. CARCINOGENIC POTENCY (q.,*) 6.3.1. Oral. Data are Insufficient to calculate a q * for oral exposure to acetone. 6.3.2. Inhalation. Data are Insufficient to calculate a q * for expo- sure to acetone by Inhalation. -12- ------- 7.
