Test material

Reference
Name:
Unnamed
Type:
Constituent
Details on test material:
- Identification: Aminopropyl Vinyl Ether
- Chemical name: 3-(ethenyloxy)propan-1-amine
- Physical form: liquid
- Appearance: colourless, clear
- Water solubility: miscible
- Density: 0.891 g/cm3 (20°C)
- Purity: 99.6 corrected area-%
- Homogeneity: homogeneous
- Storage conditions: The test substance was stored at ambient temperature (avoid temperature 25°C)

Sampling and analysis

Analytical monitoring:
yes
Details on sampling:
At the start of the exposure (0 h) samples from vessels without daphnids and at the end of the exposure (48 h) samples from vessels with daphnids were analyzed. The samples were transported to the Analytical Laboratory on the day of sampling.

Test solutions

Details on test solutions:
The volume of the test substance required for preparation of the nominal concentration was calculated from the density (d=0.891 g/cm3). Prior to use, the test substance container was shaken to ensure homogeneity.The stock solution (100 mg/L) was prepared by directly pipetting 224µL of test substance to 2L of test medium and stirring for approximately 10 min (magnetic stir plate) until visibly dissolved. The lower test concentrations were prepared by dilution of this stock solution. Before the dilution is performed, the stock solution was checked for complete dissolution of the test substance. The stock solution appeared colourless-clear.
- Test groups: 0 (control), 4.6, 10, 22, 46 and 100 mg/L as nominal concentrations based on test substance mass without a correction for purity.
