12.1 Toxicity

  • Toxicity to fish: LC50; Species: Pimephales promelas (Fathead minnow, size 17.5 mm, wt 0.085 g); Conditions: freshwater; flow-through; Concentration: 1730000 ug/L (95% confidence limit: 1510000 to 1980000 ug/L) for 4 days /active ingredient
  • 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: Triethylenediamine, present at 100 mg/L, reached 0% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L and the Japanese MITI test(1).[(1) NITE; Chemical Risk Information Platform (CHRIP). Biodegradation and Bioconcentration. Ver 2006.01.30 Updated. National Institute of Technology and Evaluation. Tokyo, Japan. Thiodiethylene glycolbicyclo

12.3 Bioaccumulative potential

BCF values of <1.3 and <13 were measured using carp (Cyprinus carpio) which were exposed over an 6-week period(1). According to a classification scheme(2), these BCF values suggest the potential for bioconcentration in aquatic organisms is low(SRC).[(1) NITE; Chemical Risk Information Platform (CHRIP). Biodegradation and Bioconcentration. Ver 2006.01.30 Updated. National Institute of Technology and Evaluation. Tokyo, Japan. Thiodiethylene glycolbicyclo

12.4 Mobility in soil

The Koc of triethylenediamine is estimated as 3.4(SRC), using a water solubility of 450 g/L(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that triethylenediamine is expected to have very high mobility in soil(SRC). The pKa1 and pKa2 values of triethylenediamine are 3.0 and 8.7(1), respectively, indicating that this compound will primarily exist in the cation form in the environment and cations generally have lower mobility in soils than their neutral counterparts(4).

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.
