12.Ecological information

12.1 Toxicity

  • Toxicity to fish: LC50; Species: Pimephales promelas (Fathead minnow); Conditions: freshwater, static, 19-20°C, pH 7.4-7.8; Concentration: 55 mg/L for 96 hr
  • Toxicity to daphnia and other aquatic invertebrates: EC50; Species: Daphnia magna (Water flea); Conditions: freshwater, static, 19-20°C, pH 7.4-7.8, dissolved oxygen 7.7-8.6 at test start and 5.5-6.1 at test end; Concentration: 2.2 mg/L for 48 hr; Effect: immobilization
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: 4-Methoxyphenol, present at 100 mg/L, reached 86% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test which classified the compound as readily biodegradable(1). An acclimated mixed bacterial population reached 57% of the theoretical BOD after 5 days(2). Varying concentrations of an acclimated mixed bacterial population resulted in biodegradation rate constants of 4.2X10-2/day, 5.0X10-2/day, 8.0X10-2/day, 1.9X10-1/day, and 2.5X10-1/day for bacterial concentrations of 2.3X10+4, 2.3X10+5, 2.3X10+6, 2.3X10+7, and 2.3X10+8 cells/L, respectively(3). 4-Methoxyphenol was biodegraded by three activated sludges with rate constants of 7.88X10-4/hr, 4.03X10-4/hr, and 3.35X10-3/hr for a non-adapted sludge, a phenol-adapted sludge, and a cresol-adapted sludge, respectively(4). Using spectrophotometric evidence, aniline-adapted activated sludge degraded 4-methoxyphenol mainly via an ortho cleavage pathway(5); phenol- and m-cresol-adapted activated sludges degraded 4-methoxyphenol mainly via a meta cleavage pathway(5). 4-Methoxyphenol, at a concentration of 0.27 mg/L was removed 95% in 1 day and 89.6% in 2 days using an activated sludge inoculum(6).

12.3 Bioaccumulative potential

An estimated BCF of 4 was calculated in fish for 4-methoxyphenol(SRC), using a log Kow of 1.41(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

An experimental Koc of 55.7 was determined for adsorption to Brookston clay loam (pH 5.7, 8.8% organic content, 22.22 cation exchange capacity)(1). Using a Lucera-clay sample (0.5% organic carbon, 11 meq/100 g cation exchange capacity), a K value of 0.45 was measured(2) which corresponds to a Koc value of 90(3). According to a classification scheme(4), these Koc values suggest that 4-methoxyphenol is expected to have high 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.
