[32], In Europe, the Scientific Committee on Occupational Exposure Limit Values (SCOEL) recommends for DCM an occupational exposure limit (8 h time-weighted average) of 100 ppm and a short-term exposure limit (15 min) of 200 ppm.

The donor hydrogen-bonding corrections of methylene chloride in these thermodynamic studies has been reported. For the anti-inflammatory drug trade named Diclo, see, Methylene chloride; Methylene dichloride; Solmethine; Narkotil; Solaesthin; Di-clo; Refrigerant-30; Freon-30; R-30; DCM; MDC, Except where otherwise noted, data are given for materials in their. [12], DCM is produced by treating either chloromethane or methane with chlorine gas at 400–500 °C. [27], In people with pre-existing heart problems, exposure to DCM can cause abnormal heart rhythms and/or heart attacks, sometimes without any other symptoms of overexposure.

Enter the desired X axis range [1][22] [12] However, the majority of dichloromethane in the environment is the result of industrial emissions. DCM chemically welds certain plastics. [20][21] It can also be absorbed through the skin. Contact your hosting provider letting them know your web server is not completing requests.

An example of a DCM heat engine is the drinking bird. Data compilation copyright In February 2013, the U.S. Occupational Safety and Health Administration (OSHA) and the National Institute for Occupational Safety and Health warned that at least 14 bathtub refinishers have died since 2000 from DCM exposure. Ozone concentrations measured at the midlatitudes from the ground up through the stratosphere from 1998 to 2016 have declined by 2.2 Dobson units. National Institute of Standards and

The IR Spectrum Table is a chart for use during infrared spectroscopy.The table lists IR spectroscopy frequency ranges, appearance of the vibration and absorptions for functional groups. [28] In animal experiments, it was fetotoxic at doses that were maternally toxic but no teratogenic effects were seen. The peaks around 3100 1/cm is due to the asymmetric stretching between the C-H atoms.

Symptoms of acute overexposure to dichloromethane via inhalation include difficulty concentrating, dizziness, fatigue, nausea, headaches, numbness, weakness, and irritation of the upper respiratory tract and eyes.

DCM is used in the material testing field of civil engineering; specifically it is used during the testing of bituminous materials as a solvent to separate the binder from the aggregate of an asphalt or macadam to allow the testing of the materials.

[22] People with existing liver, nervous system, or skin problems may worsen after exposure to methylene chloride.[9]. In this way, an estimated 400,000 tons were produced in the US, Europe, and Japan in 1993.[11]. in these sites and their terms of usage. and Informatics, Vibrational and/or electronic energy levels, Computational Chemistry Comparison and Benchmark Database, X-ray Photoelectron Spectroscopy Database, version 4.1, NIST / TRC Web Thermo Tables, "lite" edition (thermophysical and thermochemical data), NIST / TRC Web Thermo Tables, professional edition (thermophysical and thermochemical data), Modified by NIST for use in this application, evaluated Although this colorless, vola, Methylene Chloride, GCSolv (TM) - This organic compound, also known as dichloromethane, has a light sweet aroma and is widely used as a solvent.

Research is not yet clear as to what levels may be carcinogenic. Table 1.1. Exposure to dichloromethane can be moni-tored in samples of blood, breath, or urine (ATSDR, 2000; WHO, 2000; SCOEL, 2009). The purpose of the fee is to recover costs associated The following components were used in generating the plot: Additonal code used was developed at NIST:

Exposures to dichloromethane can also be monitored in air using a direct-reading infrared analyser, with a minimum detectable concentration of 0.7 mg/m3 (0.2 ppm) (Goelzer & O’Neill, 1985).
