چکیده
The chlorinated solvent, methylene chloride (also known as dichloromethane) has been used in industry for over 80 years. Its unique combination of properties low boiling point, high solvency power, relative inertness, low toxicity and non flammability has led to its wide variety of applications, such as paint and varnish removal, as an extraction medium/process solvent, and in aerosols, electronics and metal cleaning. It is the most widely-used of the chlorinated solvents, particularly for pharmaceutical production.

Qualitative and quantitative analysis of chlorinated solvents using Raman spectroscopy and machine learning
The unambiguous identification and quantification of hazardous materials is of increasing importance in many sectors such as waste disposal, pharmaceutical manufacturing, and environmental protection. One particular problem in waste disposal and chemical manufacturing is the identification of solvents into chlorinated or non-chlorinated. In this work we have used Raman spectroscopy as the basis...
متن کاملConcentrations of individual serum or plasma bile acids in workers exposed to chlorinated aliphatic hydrocarbons.
Individual serum or plasma bile acid concentrations were measured by high performance liquid chromatography in two groups of workers with differing exposures: to hexachlorobutadiene (HCBD) and a mixture of other chlorinated solvents (SOLVENT) in study A; and trichloroethylene (TCE) in study B. Exposures to HCBD and TCE were associated with highly significant increases in a number of individual ...
متن کاملThe impact of chlorinated solvent co-contaminants on the biodegradation kinetics of 1,4-dioxane.
1,4-Dioxane (dioxane), a probable human carcinogen, is used as a solvent stabilizer for 1,1,1-trichloroethane (TCA) and other chlorinated solvents. Consequently, TCA and its abiotic breakdown product 1,1-dichloroethene (DCE) are common co-contaminants of dioxane in groundwater. The aerobic degradation of dioxane by microorganisms has been demonstrated in laboratory studies, but the potential ef...
متن کاملEvaluation of Sclerotinia sclerotiorum as a potential mycotoxin producer on soybeans.
Solvent extracts of Sclerotinia sclerotiorum sclerotia were nontoxic to mice and chicken embryos; psoralens were not detected. Solvent extracts of soybeans inoculated with 10 strains of S. sclerotiorum were toxic on injection but nontoxic on per os administration to mice. The presence of chlorinated hydrocarbons in the soybeans may partially help explain toxicity by intraperitineal injection.
متن کاملOccupational exposure to solvents and risk of non-Hodgkin lymphoma in Connecticut women.
A population-based case-control study involving 601 incident cases of non-Hodgkin lymphoma (NHL) and 717 controls was conducted in 1996-2000 among Connecticut women to examine associations with exposure to organic solvents. A job-exposure matrix was used to assess occupational exposures. Increased risk of NHL was associated with occupational exposure to chlorinated solvents (odds ratio (OR) = 1...
