12.Ecological information

12.1 Toxicity

  • Toxicity to fish: LC50 Brachydanio rerio (Zebrafish) >500 mg/L/48-hr; static bioassay (OECD guideline 203)
  • 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: Decomposition of nitrobenzoic acid took greater than 64 days by a soil microflora innoculum in mineral salts medium(1). After 180 minutes, little oxygen consumption by phenol adapted biological cultures occurred with 4-nitrobenzoic acid(2). The amounts of oxygen consumed after the 180 minute test time are 55 uL (endogenous), 64 uL (cells plus 100 mg/L 3-nitrobenzoic acid), and 346 uL (cells plus phenol - after 90 minutes) which results in a ratio of only 1.2 endogenous to 4-nitrobenzoic acid oxygen consumption(2). In a 2 week Japanese MITI test using 100 mg/L 4-nitrobenzoic acid and 30 mg/L sludge, 4-nitrobenzoic had a theoretical BOD of 62%(3). 4-Nitrobenzene reached 50.2% of its 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, pH 6.8-7.0, and temperatures of 15-20°C(4).

12.3 Bioaccumulative potential

An estimated BCF of 3.2 was calculated for 4-nitrobenzoic acid(SRC), using a log Kow of 1.89(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

The Koc of 4-nitrobenzoic acid is estimated as 250(SRC), using a log Kow of 1.89(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 4-nitrobenzoic acid is expected to have moderate mobility in soil. The pKa of 4-nitrobenzoic acid is 3.44(4), indicating that this compound will exist almost 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

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.
