  12.Ecological information

  12.1 Toxicity

  Toxicity to fish: no data available

  Toxicity to daphnia and other aquatic invertebrates: no data available

  Toxicity to algae: no data available

  Toxicity to microorganisms: no data available

  12.2 Persistence and degradability

  AEROBIC: N-Methylformamide, present at 400 mg/l, reached 4%, 98%, and 100% of its theoretical BOD in 3 hrs, 3 days, and 7 days,

  respectively, using an industrial activated sludge inoculum and the Zahn-Wellens test(1). Using the BOD test, N-methylformamide achieved 2% of

  its theoretical BOD after 5 days(1). N-Methylformamide has also been shown to biodegrade by microorgansism obtained through soil

  enrichment(2). Therefore, N-methylformamide may biodegrade in the environment(SRC).

  12.3 Bioaccumulative potential

  An estimated BCF of 3 was calculated for N-methylformamide(SRC), using a log Kow of -0.97(1) and a regression-derived equation(2).

  According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

  12.4 Mobility in soil

  The Koc of N-methylformamide is estimated as 7(SRC), using a log Kow of -0.97(1) and a regression-derived equation(2). According to a

  classification scheme(3), this estimated Koc value suggests that N-methylformamide is expected to have very high mobility in soil(SRC).

  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.

  Contaminated packaging

  Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it

  unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible

  packaging materials.
