Dichloromethane is a halogenated aliphatic hydrocarbon that does not occur naturally in the environment. It is no longer produced in Canada but is still imported, primarily for use as a paint stripper, a blowing agent for foam production and a component in aerosols. The maximum acceptable concentration (MAC) for dichloromethane in drinking water is 0.05 mg/L (50 µg/L).
