Methylene chloride is removed from the body mainly in expired air and urine. In four human subjects exposed to methylene chloride (350 mg/cu m) for 2 hr, an average of 22.6 microg methylene chloride was excreted in the urine within 24 hr after the exposure. In seven subjects exposed to 710 mg/cu m for 2 hr, the corresponding value was 81.5 ug. These data show that the amount excreted in the urine is insignificant. Methylene chloride excretion in expired air was most evident during the first 30 min after exposure. Initial post-exposure concentrations of methylene chloride in expired breath following 2-and 4-hr exposure periods were about 71 mg/cu m and fell to about 18 mg/cu m at the end of 30 min. Small amounts of methylene chloride remained in the expired air at 2.5 hr.

The fat content of the body was calculated in 12 healthy male subjects aged 21 to 35 years by means of hydrostatic weighing and anthropometric estimation of skeletal weight. The subjects were exposed to a concentration of 2,600 mg of methylene chloride per cubic meter of inspired air (750 ppm) for 1 hr while performing work at an intensity of 50 W on a bicycle ergometer. The uptake in the organism was measured continuously with the Douglas bag technique. The amount of methylene chloride absorbed correlated highly with degree of obesity and body weight. Needle biopsy specimens of subcutaneous adipose tissue were taken from the buttocks before exposure and 0, 1, 2, 3 and 4 hr after exposure. The mean yield of tissue from the 72 biopsies was 25 mg. The concentration of methylene chloride in the adipose tissue was determined by gas chromatography, using a headspace method. The mean concentration was 10.2 mg/kg 1 hr after exposure and 8.4 mg/kg after 4 hr. There was a wide distribution around the mean values. In the six slim subjects the concentration in the adipose tissue during the 4 hr after exposure was on an average twice that of the six more obese subjects. On the other hand, in spite of lower concentrations, the obese subjects had a greater calculated amount of methylene chloride in the total fat depots of the body. Two subjects were studied about 22 hr after exposure, the concentration in subcutaneous adipose tissue being 1.6 and 1.7 mg/kg, respectively, at that time.

A detailed study of the relationship between the measurements of methylene chloride in expired air or blood, carbon monoxide in expired air and CO-Hb in blood was undertaken... At the end of exposure of non-smoking, sedentary volunteers for 7.5 hr to methylene chloride vapour concentrations of 180-710 mg/cu m, the mean concentration of the solvent in alveolar air and in blood, and the percent CO-Hb saturation were measured... By 7 hr after exposure to any concentration, the expired air contained less than 3.5 mg/cu m methylene chloride; at 16 hr, only negligible levels were detected. These data suggest that, due to its rapid elimination, measurements of methylene chloride in expired air are unsuitable for use as a marker of occupational exposure.

...the effects of exercise and cigarette smoking on the uptake, metabolism and excretion of methylene chloride /was investigated/. The effects of smoking and methylene chloride exposure on CO-Hb saturation levels were found to be additive. Exercise was found to increase the absorption of methylene chloride and CO-Hb levels. However, the effects of exercise on CO-Hb were not observed to increase with heavy workloads beyond the level achieved with moderate work-loads, suggesting a saturation of this effect...

A modified version of the original physiologically based pharmacokinetic (PBPK) model by Andersen et al. (1987) has been developed and used in conjunction with previously published human kinetic data for dichloromethane (DCM) metabolism and to assess interindividual variability in the rate of oxidative metabolism. Time-course data for 13 volunteers (10 males, 3 females) exposed to one or more concentrations of DCM (50 ppm, 100 ppm, 150 ppm, or 200 ppm) for 7.5 hr were used to optimize the maximal rate of hepatic metabolism (V(maxC)) through the cytochrome P450 pathway for each individual. DCM breath and blood concentrations were used, along with carboxyhemoglobin concentrations in blood and carbon monoxide (CO) concentrations in exhaled breath, to estimate the model parameters. Significant improvements in model fit were achieved when extrahepatic oxidative metabolism of DCM was added to the model structure. The 13 individual V(maxC) values ranged from 7.1 to 23.6 mg/hr/kg0.7 and appeared to be bimodally distributed. The distribution was not sex related and may be related to differential CYP2E1 induction. A comparison of the observed variation in V(maxC) values to other estimates of variability in the rate of oxidative metabolism and human CYP2E1 activity suggest a relatively narrow range in human hepatic activity toward DCM.

Dichloromethane (DCM, methylene chloride) is a lipophilic volatile compound readily absorbed and then metabolized to several metabolites that may lead to chronic toxicity in different target organs. Physiologically based pharmacokinetic (PBPK) models are useful tools for calculation of internal and target organ doses of parent compound and metabolites. PBPK models, coupled with in vivo inhalation gas-uptake data, can be useful to estimate total metabolism. Previously, such an approach was used to make predictions regarding the metabolism and to make subsequent inferences of DCM's mode of action for toxicity. However, current evidence warrants re-examination of this approach. The goal of this work was to examine two different hypotheses for DCM metabolism in mice. One hypothesis describes two metabolic pathways: one involving cytochrome P450 2E1 (CYP2E1) and a second glutathione (GSH). The second metabolic hypothesis describes only one pathway mediated by CYP2E1 that includes multiple binding sites. The results of our analysis show that the in vivo gas-uptake data fit both hypotheses well and the traditional analysis of the chamber concentration data is not sufficient to distinguish between them. Gas-uptake data were re-analyzed by construction of a velocity plot as a function of increasing DCM initial concentration. The velocity (slope) analysis revealed that there are two substantially different phases in velocity, one rate for lower exposures and a different rate for higher exposures. The concept of a "metabolic switch," namely that due to conformational changes in the enzyme after one site is occupied - a different metabolic rate is seen - is also consistent with the experimental data. Our analyses raise questions concerning the importance of GSH metabolism for DCM. Recent research results also question the importance of this pathway in the toxicity of DCM. GSH-related DNA adducts were not formed after in vivo DCM exposure in mice and DCM-induced DNA damage has been detected in human lung cultures without GSH metabolism. In summary, a revised/updated metabolic hypothesis for DCM has been examined using in vivo inhalation data in mice combined with PBPK modeling that is consistent with up-to-date models of the active site for CYP2E1 and suggests that this pathway is the major metabolizing pathway for DCM metabolism.

Dichloromethane (DCM) is a hepatic and pulmonary carcinogen in mice exposed to high doses by inhalation. It has been shown previously that the incidence of liver and lung tumors does not increase in rats or hamsters exposed to the dihaloalkane under conditions similar to those that produced tumors in mice. The biological consequences of DCM exposure to humans is therefore uncertain. The carcinogenic effects of DCM in the mouse are caused by the interaction with DNA of a glutathione (GSH) conjugate that is produced by the class theta glutathione S-transferase T1-1 (GST T1-1). The species specificity is thought to be due to the greater amount of transferase activity in mouse target organs and specific nuclear localization of GST T1-1 in target cells. This paper directly compares the relative capacity and locality of DCM activation in mouse and human tissues. The results show that mouse GST T1-1 is more efficient in catalyzing the conjugation of DCM with GSH than the orthologous human enzyme. In addition, the mouse expresses higher levels of the transferase than humans in hepatic tissue. Histochemical analysis confirmed the presence of GST T1-1 in the nucleus of mouse liver cells. However, in human liver GST T1-1 was detected in bile duct epithelial cells and hepatocyte nuclei but was also present in the cytoplasm. Taking this information into account, it is unlikely that humans have a sufficiently high capacity to activate DCM for this compound to be considered to represent a carcinogenic risk.

Dichloromethane (DCM) elimination and carboxyhemoglobin (COHb) generation were examined in adult female SD rats pretreated with a glutathione (GSH) depletor(s). Rats were treated with either buthionine sulfoximine (BSO; 2 mmol/kg, i.p.), diethylmaleate (DEM; 3 mmol/kg, i.p.), phorone (PHO; 1 mmol/kg, i.p.) or BSO plus PHO (BSO; 2 mmol/kg +PHO; 0.5 mmol/kg, i.p.). ...The half-life of DCM in blood was also increased in rats pretreated with the GSH depletor(s).

When rats (male, Sprague-Dawley) were exposed to 50, 500, and 1500 ppm methylene chloride (dichloromethane, DCM) for 6 hr, plasma dichloromethane levels at apparent steady state were disproportionately higher with increasing exposure concn. Blood carboxyhemoglobin (HbCO) was 3% at 50 ppm and 10-13% at 500 ppm and at 1500 ppm. At the end of the 6 hr exposure, HbCO levels declined with half-life of 23 min.

The mechanism by which methylene chloride induces mammary adenomas in the rat is important for human hazard assessment. Female Sprague- Dawley rats receiving methylene chloride have a high blood level of prolactin. In common with the response to other agents which act via hyperprolactinaemia, the methylene chloride-induced response is of benign neoplasms only. There is no evidence for the binding of methylene chloride to the DNA of other tissues and hence it seems unlikely that it will bind to mammary tissue when the primary site of metabolism is the liver. It seems most likely, therefore, that the increased incidence of mammary adenomas is the result of an indirect mechanism operating via hyperprolactinaemia.

Dichloromethane (DCM) is considered a probable human carcinogen. Laboratory studies have shown an increased incidence of lung and liver cancer in mice but not in rats or hamsters. Despite the correlation between metabolism of DCM by the glutathione-S-transferase (GST) pathway and the occurrence of tumors in different species, the mechanism of tumor induction by DCM metabolites produced through the GST pathway remains unclear. In this study a V79 cell line stably transfected with the murine GST theta 1 gene (mGSTT1) was compared to the parent cell line (MZ) to determine how the construct affects DCM metabolism and the sensitivity of the cell line to DNA damage and cytotoxicity. V79 cells were treated with DCM (2.5-10mM) or formaldehyde (150-600muM) for 2hr. Also, formaldehyde produced by V79 cytosol metabolism of DCM was measured spectrophotometrically. DNA damage and DNA-protein crosslinks were measured by the standard and proteinase K-modified alkaline single cell gel electrophoresis (SCG) assays. Cytotoxicity was assessed by trypan blue stain exclusion, the Live/Dead((R)) cell viability/cytotoxicity kit for animal cells, and the neutral red assay. After DCM treatment a significant concentration-dependent increase in tail moment in the V79 MZ cells was observed compared to a significant concentration-dependent decrease in tail moment in the V79 mGSTT1 cells. Post-incubation with proteinase K significantly increased DNA migrations in DCM-treated V79 mGSTT1 cells. DCM formed significantly higher levels of formaldehyde in the cytosol of the V79 mGSTT1 cells than in the cytosol of the V79 MZ cells. Results using the cytotoxicity assays were comparable using the trypan blue and Live/Dead((R)) assays, neither showing a difference in response between the two cell lines when exposed to either formaldehyde or DCM. These results indicate that V79 mGSTT1 can metabolize DCM to a genotoxic and cytotoxic metabolite, which is likely formaldehyde...

The correlation between biol activity (toxicity and mutagenic effectiveness in Salmonella TA 100) and reactivity towards strong nucleophiles indicates that reactions with nucleophilic groups of high reactivity in biological materials, possibly SH or amino groups in proteins, are involved in dichloromethane's mechanism of action.

Increases in the concn of dichloromethane (DCM) lower the oxygen affinity of human hemoglobin as demonstrated by the shift of the oxygenation curves to higher partial pressures of oxygen and increase in the p50 (oxygen pressure necessary for fractional saturation of 0.50). Dichloromethane binds weakly to hemoglobin at four different sites, but binding to only one site is responsible for decreasing the oxygen affinity of hemoglobin.
