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.
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 ...

The values presented below are from Annex 1, Table 1, "Groundwater target values and soil and groundwater intervention values". In previous versions of the Dutch Standards, target values for soil were also present. However, in the 2009 version, target values for soils have been deleted for all compounds except metals.

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. [5]
Soil contamination, soil pollution, or land pollution as a part of land degradation is caused by the presence of xenobiotic (human-made) chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste .
