    Dichloromethane (DCM, or methylene chloride) is an organic compound with the formula CH2Cl2. This colorless, volatile liquid with a moderately sweet aroma is widely used as a solvent. Although it is not miscible with water, it is miscible with many organic solvents. One of the most well-known applications of dichloromethane is in the drinking bird heat engine.

    • Toxicity to algae: no data available
    • Toxicity to microorganisms: no data available

    12.2 Persistence and degradability

    AEROBIC: Dichloromethane is reported to completely biodegrade under aerobic conditions with sewage seed or activated sludge between 6 hours to 7 days(1-5). Dichloromethane, present at 100 mg/L, reached 13% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test (OECD 301C Method)(6). Using a respirometer test method, 49% of initial dichloromethane (10 mg/L) biodegraded using an adapted activated sludge inoculum(7). Using a Sapromat respirometer test method, nearly 100% of initial dichloromethane (660 mg/L) biodegraded using an adapted sewage inoculum(7). Dichloromethane was degraded at a concentration of 3.3 mg/L in the aqueous phase of natural sediment with a corresponding half-life of 10.9 days(8). Dichloromethane, at 50 mg/L, had 0% degradation in a Manometric respirometry test over a 28-day incubation period(9).

    12.3 Bioaccumulative potential

    Using carp (Cyprinus carpio) which were exposed over a 6-week period, a BCF range of 2.0-40 was determined for dichloromethane at initial concentrations of 25 and 250 ug/L(1). According to a classification scheme(2), this BCF range suggests bioconcentration in aquatic organisms is low to moderate(SRC).

    12.4 Mobility in soil

    Dichloromethane has reported experimentally derived Koc values of 28(1), 36(2), 48 and 8(3). According to a classification scheme(4), these Koc values suggest that dichloromethane is expected to have very high mobility in soil. Dichloromethane is adsorbed strongly to peat moss, less strongly to clay, only slightly to dolomite limestone, and not at all to sand(5).

    12.5 Other adverse effects

    no data available

    13.Disposal considerations

    13.1 Disposal methods


    The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
