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

Using the MITI test, 100 mg/l of p-dibromobenzene was innoculated with activated sludge(1). After an incubation period of two weeks, a theoretical BOD of 0 percent was obtained.

12.3 Bioaccumulative potential

An experimental BCF value of 1,413 was determined for p-dibromobenzene(2,SRC) in the guppy (Poecilia reticulata). Studies also showed a depuration rate constant of 1.41 /d(2). When exposed to 10 ug/l p-dibromobenzene, the experimental BCF in carp ranged from 42.9 to 313. When exposed to 1 ug/l p-dibromobenzene, the experimental BCF ranged from 44.2 to 279(1). According to a classification scheme(3), these BCF values suggest that bioconcentration in aquatic organisms is moderate to very high(SRC).

12.4 Mobility in soil

The Koc of p-dibromobenzene is estimated as approximately 2,700(SRC), using an experimental log Kow of 3.79(1,SRC) and a regression-derived equation(2,SRC). According to a recommended classification scheme(3), this estimated Koc value suggests that p-dibromobenzene has slight mobility in soil(SRC).

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.
