| Gefahrenübersicht | Bis(2-chloroethyl) ether is a colorless, nonflammable liquid with a strong unpleasant odor. It dissolves easily in water, and some of it will slowly evaporate to the air. It does not occur naturally. Bis(2-chloroethyl) ether is made in factories, and most of it is used to make pesticides. Some of it is used as a solvent, cleaner, component of paint and varnish, rust inhibitor, or as a chemical intermediate to make other chemicals.Dichloroethyl ether is mainly used as a chemical intermediate in industry. Limited health effects information is available on this chemical. The major effect from acute (short-term) inhalation exposure to dichloroethyl ether in humans is extreme irritation of the respiratory tract and skin. Dichloroethyl ether has been shown to be carcinogenic in animal studiesan increased incidence of liver tumors in mice has been reported. EPA has classified dichloroethyl ether as a Group B2, probable human carcinogen.Damage to the lungs, liver, kidneys, and brain occur in studies of guinea pigs and rats at 500 ppm for 5 to 8 hours. Volunteers found exposures above 550 ppm intolerable because of nauseating odor and irritation of the eyes, nose, and respiratory tract. [ACGIH] The vapor can cause lacrimation.[HSDB] A severe eye irritant[CHEMINFO] Some animal studies indicate that bis(2-chloroethyl) ether can affect the nervous system resulting in sluggish and slow movement, staggering, unconsciousness, and death.

The method was illustrated using seven waste forms containing four organic contaminants. Containment was mainly physical for phenol and aniline, while chemical containment was more important for acenaphthene and bis (2-chloroethyl/ether). The method proposed involves a simple addition to the ANSI/ANS 16.1 protocol and it can be used to determine the importance of waste form durability for the long-term containment of contaminants. |

| Umweltverhalten | TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 120(SRC), determined from a log Kow of 1.29(2) and a regression-derived equation(3), indicates that bis(2-chloroethyl) ether is expected to have high mobility in soil(SRC). Volatilization of bis(2-chloroethyl) ether from moist soil surfaces is expected to be important(SRC) given an estimated Henry's Law constant of 2.9X10-5 atm-cu m/mole(SRC), calculated from its vapor pressure(4) and water solubility(5). In a 140 cm long column containing Lincoln fine sand collected in Ada, OK, 86% of the applied bis(2-chloroethyl) ether reached 140 cm, indicating minimal adsorption to this soil(6). The potential for volatilization of bis(2-chloroethyl) ether from dry soil surfaces may exist(SRC) based on a vapor pressure of 1.55 mm Hg(4). No data concerning the hydrolysis of bis(2-chloroethyl) ether in soil were available. The hydrolysis rate constant for bis(2-chloroethyl) ether in water was determined to be 2.6X10-5/hour under neutral conditionsthis corresponds to a half-life at pH 7 and 25 °C of 3 years(7). Bis(2-chloroethyl) ether may be resistant to biodegradation under aerobic conditions in environmental media based upon screening test data from studies using activated sludge(8,RC). In one study, bis(2-chloroethyl) ether showed 50% biodegradation after 30 days when incubated with Ohio River wateracclimation appears to be important(9). In general, many ethers are known to be resistant to biodegradation(10).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 120(SRC), determined from a log Kow of 1.29(2) and a regression-derived equation(3), indicates that bis(2-chloroethyl) ether is not expected to adsorb to suspended solids and sediment in water(SRC). Bis(2-chloroethyl) ether is expected to volatilize from water surfaces(3,SRC) based on an estimated Henry's Law constant of 2.9X10-5 atm-cu m/mole(SRC), calculated from its vapor pressure(4) and water solubility(5). Estimated volatilization half-lives for a model river and model lake are 40 hours and 16 days, respectively(3,SRC). According to a classification scheme(6), a BCF of 0.4 to 1.3(7) suggests the potential for bioconcentration in aquatic organisms is low(SRC). In one study, bis(2-chloroethyl) ether showed 50% biodegradation after 30 days when incubated with Ohio River wateracclimation appears to be important(8). Bis(2-chloroethyl) ether may be resistant to biodegradation under aerobic conditions in environmental media based upon screening test data from studies using activated sludge(7,SRC). In general, many ethers are known to be resistant to biodegradation(9). The hydrolysis rate constant for bis(2-chloroethyl) ether in water was determined to be 2.6X10-5/hour under neutral conditionsthis corresponds to a half-life at pH 7 and 25 °C of 3 years(10). The hydrolysis half-life of bis(2-chloroethyl) ether in demineralized water at 25 °C was determined to be 22 years(11). 2-(2-Chloroethoxy) ethanol and diethylene glycol were determined to be the major hydrolysis by-products of bis(2-chloroethyl) ether(12).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), bis(2-chloroethyl) ether, which has a vapor pressure of 1.55 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase bis(2-chloroethyl) ether 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 5 days(3,SRC). Direct photolysis in the atmosphere is not expected to be a major significant degradation process since no functional groups are present in bis(2-chloroethyl) ether that would lead to absorption of sunlight(SRC). |

Other limited studies in rats and mice using oral gavage, subcutaneous or intraperitoneal injection and skin painting failed to confirm these findings. ... BCEE was found to be irritating to the eyes and nasal passages of humans ... following short term exposure. No epidemiological studies on the effects of long term exposure to BCEE have been reported. ... None of the long term studies in laboratory animals is of sufficient quality to provide quantitative information on either the potential of BCEE to cause cancer or the toxicological effects produced by long term exposure to this substance.BCEE is extremely meabolized, with thiodiglycolic acid (TDGA) being the principal endproduct. The pathway leading to TDGA formation is uncertain, but probably involves oxidative cleavage of the ether bond to yield chloroacetaldehyde and 2-chloroethanol. (L183) |

Bis(2-chloroethyl) ether was identified in a synthetic rubber plant effluent - 0.16 mg/l(2). The concn of bis(2-chloroethyl) ether identified in leachate from 58 landfills across North America was determined to be 12.4 mg/l(3). Bis(2-chloroethyl) ether was detected in raw sludge and treated sludge, concns unknown, in samples taken from 37 water pollution control plants in Ontario, Canada between January and July 1986(4). Bis(2-chloroethyl) ether was detected but not quantified in stack emissions from a hazardous waste incinerator in California(5). |

| RCRA-Anforderungen | U025As stipulated in 40 CFR 261.33, when bis(2-chloroethyl) ether, 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). |
| Luftstandards | This action promulgates standards of performance for equipment leaks of Volatile Organic Compounds (VOC) in the Synthetic Organic Chemical Manufacturing Industry (SOCMI). The intended effect of these standards is to require all newly constructed, modified, and reconstructed SOCMI process units to use the best demonstrated system of continuous emission reduction for equipment leaks of VOC, considering costs, non air quality health and environmental impact and energy requirements. Dichloroethyl ether is produced, as an intermediate or a final product, by process units covered under this subpart.Listed as a hazardous air pollutant (HAP) generally known or suspected to cause serious health problems. The Clean Air Act, as amended in 1990, directs EPA to set standards requiring major sources to sharply reduce routine emissions of toxic pollutants. EPA is required to establish and phase in specific performance based standards for all air emission sources that emit one or more of the listed pollutants. Bis(2-chloroethyl)ether is included on this list. |
| CERCLA-Meldepflichtmengen | Persons in charge of vessels or facilities are required to notify the National Response Center (NRC) immediately, when there is a release of this designated hazardous substance, in an amount equal to or greater than its reportable quantity of 10 lb or 4.54 kg. The toll free number of the NRC is (800) 424-8802In the Washington D.C. metropolitan area (202) 426-2675. The rule for determining when notification is required is stated in 40 CFR 302.4 (section IV. D.3.b).Releases of CERCLA hazardous substances are subject to the release reporting requirement of CERCLA section 103, codified at 40 CFR part 302, in addition to the requirements of 40 CFR part 355. Dichloroethyl ether is an extremely hazardous substance (EHS) subject to reporting requirements when stored in amounts in excess of its threshold planning quantity (TPQ) of 10,000 lbs. |
| Clean Water Act Anforderungen | For the maximum protection of human health from the potential carcinogenic effects due to exposure of bis(2-chloroethyl)ether through ingestion of contaminated water and contaminated aquatic organisms, the ambient water concentrations should be zero based on the non-threshold assumption for this chemical. However, zero level may not be attainable at the present time. Therefore, the levels which may result in incremental increase of cancer risk over the lifetime are estimated at 1x10-5, 1x10-6, and 1x10-7. The corresponding recommended criteria are 0.30 ug/l, 0.030 ug/l, and 0.003 ug/l, respectively. If the above estimates are made for consumption of aquatic organisms only, excluding consumption of water, the levels are 13.6 ug/l, 1.36 ug/l, and 0.136 ug/l, respectively.Toxic pollutant designated pursuant to section 307(a)(1) of the Clean Water Act and is subject to effluent limitations. /Chloralkyl ethers/ |
