Test organisms
- Test organisms (species):
- Daphnia magna
- Details on test organisms:
- Species: Daphnia magna (Straus), clone 5
Age at Test Start: 6 - 21 hours old
Sex: female
Origin:
-supplier 1997 by the Umweltbundesamt, Institut für Wasser-Boden-und Lufthygiene, Berlin, Germany.
Breeding Conditions:
- The daphnia were bred in the laboratories of IBACON under similar temperature and light conditons as in the test, and in reconstituted water of a similar quality regarding tp pH, components of the main ions and total hardness as the test water used in the test. The test organisms were not first brood progency.
Toxic Standard:
- For the evaluation of the quality of the daphnia clone and the experimental conditions the substance potassium dichromate p.A. (E. Merck, Darmstadt, Germany) is tested at least twice a year to deminstrate satisfactory test conditions.
Acclimatisation:
for 6 hours under test conditions.

Applicant's summary and conclusion
- Conclusions:
- The 24-hour EC 50 and EC 100 of the test item were higher than 100 mg test item/L. The 24-hour EC 0 was at least 100 mg test item/L.
The 48-hour EC 50 and the EC 100 were higher than 100 mg test itemIL. The 48-hour EC 0 and the 48-hour NOEC (highest concentration tested
without toxic effects after 48 hours) of N-Isopropylnortropin were determined to be 21 mg test item/L, since no significant immobilization rate
and no other signs of intoxication were observed at the test animals up to and including this test concentration.
