    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: 3-Nitrobenzene reached 42.0% of its theoretical BOD in river water collected from Songhua River, China after 5 days. The river water samples contained about 8.0 mg/L dissolved oxygen, 800-3000/mL bacteria counts, exhibited a pH 6.8-7.0, and temperatures of 15-20°C(1). Decomposition of nitrobenzoic acid by soil microflora inoculum took greater than 64 days(2). After 210 minutes, little oxygen consumption by phenol adapted biological cultures occurred with 3-nitrobenzoic acid(3). The amounts of oxygen consumed after the 210 minute test time are 83 ul (endogenous), 96 ul (cells plus 100 mg/L 3-nitrobenzoic acid), and 342 ul (cells plus phenol - after 90 minutes) which results in a ratio of only 1.2 endogenous to 3-nitrobenzoic acid oxygen consumption(3). 3-Nitrobenzoic acid, present at 100 mg/L, reached 0-12% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L and the Japanese MITI test(4).

    12.3 Bioaccumulative potential

    An estimated BCF of 3.2 was calculated for 3-nitrobenzoic acid(SRC), using a log Kow of 1.83(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), provided the compound is not metabolized by the organism(SRC).

    12.4 Mobility in soil

    The Koc of 3-nitrobenzoic acid is estimated as 240(SRC), using a log Kow of 1.83(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 3-nitrobenzoic acid is expected to have moderate mobility in soil. The pKa of 3-nitrobenzoic acid is 3.46(4), indicating that this compound will existalmost entirely in the anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5).

    12.5 Other adverse effects

    no data available

    13.Disposal considerations

    13.1 Disposal methods


    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.
