SECTION 12: Ecological information

Toxicity

  • Toxicity to fish: LC50 - Pimephales promelas - 49.7 mg/L - 96 h.
  • Toxicity to daphnia and other aquatic invertebrates: EC50 - Daphnia magna - ca. 4.2 mg/L - 48 h.
  • Toxicity to algae: EC50 - Chlorella pyrenoidosa - 22 mg/L - 96 h.
  • Toxicity to microorganisms: EC50 - other fungi: Phytium ultimum Trow. - ca. 30 mg/L - 88 h.

Persistence and degradability

AEROBIC: 4-Nitrotoluene, present at 100 mg/L, reached 0.8% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(1) which indicates the compound is not readily biodegradable(1). Two studies demonstrated that 4-nitrotoluene could be completely degraded by unacclimated sludge withing two weeks when lower concentrations of 4-nitrotoluene (10 ppm) were used(2,3). When nitrotoluene-adapted activated sludges were used as an inoculum, however, 4-nitrotoluene was almost completely degraded (~98%) within 5 days, even when higher concentrations (200 mg/L) of 4-nitrotoluene were used(4). 2-Amino-4-methylphenol has been identified as a microbial degradation product of 4-nitrotoluene(5). Using a mixed culture isolated from a contaminated soil (near an ammunition plant), 4-nitrotoluene (at initial concentrations of 5 mg/L) degraded completely in 1 to 3 days in aerobic batch and continuous reactor tests(6).

Bioaccumulative potential

An estimated BCF of 13 was calculated for 4-nitrotoluene(SRC), using a log Kow of 2.37(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). The BCF for 4-nitrotoluene has been measured to be low in an unidentified fish and in carp (Carprinus carpio)(4,5).

Mobility in soil

A log Koc value of 2.14 (Koc = 138) was experimentally determined for 4-nitrotoluene in a single lake sediment from China(1). Using a structure estimation method based on molecular connectivity indices(2), the Koc of 4-nitrotoluene can be estimated to be 363(SRC). According to a classification scheme(3), the estimated and experimental Koc values suggest that 4-nitrotoluene is expected to have high to moderate mobility in soil.

Other adverse effects

no data available

SECTION 13: Disposal considerations

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.
