  • 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

Data specific to the rate of environmental biodegradation of 2-methyl-1-butanol were not located. However, many biodegradation studies have demonstrated that the lower molecular weight aliphatic alcohols that are similar in structure to 2-methyl-1-butanol (such as 2-methyl-1-propanol) are readily biodegradable(1-11). This analogy indicates that 2-methyl-1-butanol is also likely to be readily biodegradable in the environment(SRC).

12.3 Bioaccumulative potential

Based upon a water solubility of 30,000 mg/l at 25°C(1), the BCF for 2-methyl-1-butanol can be estimated to be 1.8 from a regression-derived equation(2,SRC). Based upon a measured log Kow of 1.29(3), the BCF for 2-methyl-1-butanol can be estimated to be 5.6 from a regression-derived equation(2,SRC). These BCF values suggest that 2-methyl-1-butanol will not bioconcentrate significantly in aquatic organisms(SRC).

12.4 Mobility in soil

Based upon a water solubility of 30,000 mg/l at 25°C(1), the Koc for 2-methyl-1-butanol can be estimated to be 15 from a regression-derived equation(2,SRC). Based upon a measured log Kow of 1.29(3), the Koc for 2-methyl-1-butanol can be estimated to be 120 from a regression-derived equation(2,SRC). These BCF values suggest that 2-methyl-1-butanol has high to very high soil mobility(4).

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 Disposal methods

Product

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.
