MALE RATS GIVEN SINGLE ORAL DOSE OF BIS(2-CHLOROETHYL)ETHER, TWO METABOLITES WERE IDENTIFIED IN URINE SAMPLES: THIODIGLYCOLIC ACID (TDGA) & 2-CHLOROETHYL BETA-D-GLUCURONIC ACID.
MALE RATS WERE GIVEN A SINGLE ORAL DOSE OF 40 MG/KG (14)C-LABELED BIS(2-CHLOROETHYL) ETHER (BCEE). THIODIGLYCOLIC ACID ACCOUNTED FOR APPROX 75% OF THE TOTAL URINARY (14)C COLLECTED AFTER THE (1-(14)C)BIS(2-CHLOROETHYL) ETHER DOSE. LESSER METABOLITES OF BCEE WERE (2-CHLOROETHOXY)ACETIC ACID (5%), AND N-ACETYL-S-(2-(2-CHLOROETHOXY)ETHYL)-L-CYSTEINE (7%).
Either 40 umole or 160 umole DCEE was injected into male Wistar rats and the metabolites, thiodiglycolic acid (TdGA) and hydroxyethyl mercapturic acid (HEMA), were determined in the 24 hr urine specimens. ...
... In a further step, inhalation experiments were performed to determine urinary excretion of the two metabolites after an 8 hr exposure of male Wistar rats to 10, 50, 100, and 500 ppm DCEE ... .
BCEE is absorbed following inhalation exposure, oral administration, as well as contact to the skin. BCEE is distributed through the body, but highest levels are found in the liver, kidney and small intestine, while much lower levels are found in lung, spleen and muscle. BCEE is extensively metabolized to thiodiglycolic acid (TDGA), 2-chloroethoxyacetic acid (CEAA), and N-acetyl-S-[2-(2-chloroethoxy)ethyl]-L-cysteine, with TDGA being the principal endproduct. Smaller amounts of BCEE are metabolized by oxidation or substitution at a chlorine without ether cleavage. Approximately 80% of BCEE administered orally is excreted as TDGA within 48 hours. Smaller amounts are excreted in feces or expired air and only a very small fraction of the dose remains in the body. This indicates that BCEE is effectively excreted, and that it has a low tendency to accumulate in tissues. (L183, A129)
Quantitative information on the kinetics and metabolism of BCEE /bis(2-chloroethyl) ether/... in humans is not available. ... Limited data show that radioactive BCEE administered to rats by inhalation or gavage is rapidly absorbed. ... BCEE is readily metabolized in rats. The principal metabolite is thiodiglycolic acid ... BCEE is eliminated quickly in both rats and rhesus monkeys. ... BCEE is acutely toxic by the oral, inhalation or dermal routes of exposure. ... Exposure of laboratory animals by inhalation to high single concentrations ... resulted in eye irritation as well as congestion, edema, and hemorrhage in the lungs. ... In general, positive results were obtained when ... tested for mutagenicity in vitro. ... /In one study/ there was a significant increase in the incidence of hepatomas (combined benign hepatomas and malignant tumors) compared to unexposed controls. ... 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)

Cancer Classification: Group B2 Probable Human Carcinogen
CLASSIFICATION: B2; probable human carcinogen. BASIS FOR CLASSIFICATION: Positive carcinogenicity results in two strains of mice and evidence of mutagenicity. HUMAN CARCINOGENICITY DATA: None.
Evaluation: There is inadequate evidence for the carcinogenicity of bis(2-chloroethyl)ether in humans. There is limited evidence in experimental animals for the carcinogenicity of bis(2-chloroethyl)ether. Overall evaluation: Bis(2-chloroethyl)ether is not classifiable as to its carcinogenicity in humans (Group 3).
MALE RATS WERE GIVEN A SINGLE ORAL DOSE OF 40 MG/KG (14)C-LABELED BIS(2-CHLOROETHYL) ETHER (BCEE). EXCRETION OF (14)CARBON DIOXIDE AND URINARY (14)C FOLLOWED FOR 48 HR. THE TIME REQUIRED TO ELIMINATE ONE HALF OF THE DOSE WAS 12 HR FOR (1-(14)C)BCEE. EXPIRED (14)CARBON DIOXIDE ACCOUNTED FOR 11.5% OF THE DOSE, URINARY (14)C ACCOUNTED FOR 64.7%, AND 2.4% WAS FOUND IN THE FECES.
Either 40 umole or 160 umole DCEE was injected into male Wistar rats and the metabolites, thiodiglycolic acid (TdGA) and hydroxyethyl mercapturic acid (HEMA), were determined in the 24 hr urine specimens. ... Analysis of the metabolites showed that hydroxymethyl mercapturic acid excretion was much lower than the excretion of thiodiglycolic acid following the uptake of DCEE ... .
