Dichloromethane (DCM, methylene chloride, or methylene bichloride) is an organochlorine compound with the formula C H 2 Cl 2. This colorless, volatile liquid with a chloroform -like, sweet odor is widely used as a solvent .
The most important is dichloromethane, which is mainly used as a solvent. Chloromethane is a precursor to chlorosilanes and silicones . Historically significant (as an anaesthetic), but smaller in scale is chloroform, mainly a precursor to chlorodifluoromethane (CHClF 2 ) and tetrafluoroethene which is used in the manufacture of Teflon.
A Stagnosol in the World Reference Base for Soil Resources (WRB) is soil with strong mottling of the soil profile due to redox processes caused by stagnating surface water. Stagnosol (Ah-Bg1-Bgc-Bg2) showing pooled water. Stagnosols are periodically wet and mottled in the topsoil and subsoil, with or without concretions and/or bleaching.

The benefits of SOM result from several complex, interactive, edaphic factors; a non-exhaustive list of these benefits to soil function includes improvement of soil structure, aggregation, water retention, soil biodiversity, absorption and retention of pollutants, buffering capacity, and the cycling and storage of plant nutrients.
Ancylobacter dichloromethanicus is an aerobic, Gram-negative bacteria from the family of Xanthobacteraceae which has been isolated from dichloromethane contaminated soil in Volgograd in Russia. [ 1 ] [ 4 ] [ 3 ] [ 5 ] Ancylobacter dichloromethanicus can use dichloromethane , methanol , formate and formaldehyde for its metabolism.
Toxicity characteristic leaching procedure (TCLP) is a soil sample extraction method for chemical analysis employed as an analytical method to simulate leaching through a landfill. The testing methodology is used to determine if a waste is characteristically hazardous, i.e., classified as one of the "D" listed wastes by the U.S. Environmental ...
