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: Benzofuran has been shown to biodegrade in the presence of creosote-adapted microorganisms(SRC). Benzofuran biodegraded using a enriched culture from a creosote contaminated site(1) where biodegradation of benzofuran was enhanced by the degradation of other creosote compounds(1). Benzofuran was completely removed in combination with toluene, p-xylene, m-xylene, naphthalene, 1-methylnapthalene within the first 12 days of incubation, compared with a 7% loss in the acidified control microcosm(1). After 27 days, complete removal of benzofuran was observed in combination with other primary creosote substituents except 1-methylnapthalene where 95% removal was observed(1). In a study using aerobic groundwater microcosms, benzofuran at 3.3 mg/l degraded completely after 95 days (lag period = 70 days) from an aquifer contaminated with creosote compounds while from a background aquifer, benzofuran degraded after 285 days (lag period = 278 days)(2).

12.3 Bioaccumulative potential

The BCF of benzofuran in guppies exposed to 100-250 ul of a hetero PAH in 3 liters of 1:1 tapwater/deionized water for 48 hours was 360(1). According to a classification scheme(2), this BCF suggests bioconcentration in aquatic organisms is moderate(SRC).

12.4 Mobility in soil

The Koc of benzofuran is estimated as 680(SRC), using a log Kow of 2.67(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that benzofuran is expected to have low mobility in soil(SRC). Sorption of creosote compounds (including benzofuran) were measured on natural clayey till soil column(4). A Kd of 1.4 l/kg was measured for benzofuran (in presence of other creosote compounds) with a time for 50% breakthrough on the column nearly equivalent to non-adsorbing bromide ions (e.g., 37 days)(4). This data suggests that benzofuran is weakly sorbed on clayey till 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.
