12.Ecological information

12.1 Toxicity

  • Toxicity to fish: LC50; Species: Pimephales promelas (Fathead Minnow); Conditions: freshwater, static, 22.0-23.0°C, pH 8.07-8.25, hardness 288 mg/L CaCO3, dissolved oxygen 4.8-7.0 mg/L; Concentration: 775000 ug/L for 96 hr (95% confidence interval: 698000-860000 ug/L)
  • Toxicity to daphnia and other aquatic invertebrates: no data available
  • Toxicity to algae: EC50; Species: Anabaena flosaquae (Blue-Green Algae) 10000 cells; Conditions: freshwater, static, 24°C; Concentration: 17500 ug/L for 96 hr; Effect: growth, general
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: The concentration of N-nitrosodiethylamine (18.0 ppm nitroso-N) in lake water was essentially unchanged after 108 days incubation in the dark at 30°C. While the level of N-nitrosodiethylamine amended with raw sewage at pH 6.0 slowly decreased from approximately 17 ppm to 12 ppm over 14 days; the fact that the decrease was nearly the same in sterilized samples indicates that abiotic factors may have been responsible for the loss. At pH 7.2 the rate of loss was greater than for autoclaved sewage, however heat treatment may have altered sample properties so that nonbiological loss was diminished(1).

12.3 Bioaccumulative potential

An estimated BCF of 3 was calculated in fish for N-nitrosodiethylamine(SRC), using a log Kow of 0.48(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 N-nitrosodiethylamine can be estimated to be 83(SRC). The Koc of N-nitrosodiethylamine can be estimated as 14(SRC), using a log Kow of 0.48(2) and a regression-derived equation(1). According to a classification scheme(3), these estimated Koc values suggest that N-nitrosodiethylamine is expected to have very high to high mobility in soil.

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.
