12.Ecological information

12.1 Toxicity

  • Toxicity to fish: LC50; Species: Brachydanio rerio (Zebrafish); Concentration: 24 mg/L for 96 hr /Conditions of bioassay not specified
  • 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: In an aerobic screening study using acclimated activated sludge inoculum, o-phenylenediamine (initial concentration of 25 to 30 ppm) exhibited 33% removal after 5 days incubation(1). In a screening test using soil microflora and an initial concentration of 10 ug/mL o-phenylenediamine, the decomposition period was observed to be >64 days for total loss of ultraviolet absorbency at a wavelength of 294 nm(2). o-Phenylenediamine (initial concentration of 500 ppm) exhibited a 44.5% theoretical BOD after 8 days in a Warburg respirometer using aniline-acclimated sludge at 20°C(3). o-Phenylenediamine, 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(4).

12.3 Bioaccumulative potential

An estimated BCF of 3 was calculated in fish for o-phenylenediamine(SRC), using a log Kow of 0.15(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

Using a structure estimation method based on molecular connectivity indices(1), the Koc of o-phenylenediamine can be estimated to be 34(SRC). According to a classification scheme(2), this estimated Koc value suggests that o-phenylenediamine is expected to have very high mobility in soil. However, aromatic amines are expected to bind strongly to humus or organic matter in soils due to the high reactivity of the aromatic amino group(3,4), suggesting that mobility may be much lower in some soils(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.
