  • Toxicity to daphnia and other aquatic invertebrates: no data available
  • Toxicity to algae: no data available

12.2 Persistence and degradability

AEROBIC: The bacteria Arthrobacter sp. HA-1 was found to have a growth yield of 4.1 g protein/(mol C) on 1-bromobutane(1). Substrate utilization was measured by halide release and in this case a 96% bromine release was measured(1). Arthrobacter sp. HA-1 has been shown to grow on 1-bromobutane at a rate of 0.11 per hour(2).

12.3 Bioaccumulative potential

An estimated BCF of 26 was calculated for 1-bromobutane(SRC), using a log Kow of 2.75(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

Using a structure estimation method based on molecular connectivity indices(1), the Koc of 1-bromobutane can be estimated to be 80(SRC). According to a classification scheme(2), this estimated Koc value suggests that 1-bromobutane is expected to have high mobility in soil.

12.5 Other adverse effects

no data available

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.
