12.1 Toxicity

  • Toxicity to fish: LC50; Species: Pimephales promelas (Fathead minnow, age 30-31 days, mean length 18.4 mm, mean weight 0.086 g); Conditions: freshwater, flow through, 25.3°C, pH 7.5, hardness 45.1 mg/L CaCO3, alkalinity 39.6 mg/L CaCO3, dissolved oxygen 6.5 mg/L; Concentration: 60.9 ug/L for 96 hr /97% purity
  • 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: 2,4,6-Tris(1,1-dimethylethyl)phenol, present at 100 mg/L, reached 0% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1).

12.3 Bioaccumulative potential

BCF values of 4,830-16,000 and 4,320-23,200 were measured in carp (Cyprinus carpio) exposed to 10 and 1 ppb, respectively, of 2,4,6-tris(1,1-dimethylethyl)phenol over an 8-week period(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is very high(SRC).

12.4 Mobility in soil

The Koc of 2,4,6-tris(1,1-dimethylethyl)phenol is estimated as 63,000(SRC), using a log Kow of 6.06(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 2,4,6-tris(1,1-dimethylethyl)phenol is expected to be immobile in soil.

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.
