Constituent 1
- Specific details on test material used for the study:
- 2-Fluorobenzoyl-Chloride / 393-52-2 / 206-87-2
Test solutions
- Vehicle:
- yes
- Details on test solutions:
- In the pre-experiment to the solubility of the test item, its half-life in test water was determined to be less than 1.5 hours. After 20 hours, the substance has been converted to the corrisponding 2-Fluorobenzoic Acid. Therfore, according to international recommendations for substances with a hal-life less than 4 hours, the breakdown product of the parent substance was tested for its toxicity.
Test organisms
- Test organisms (species):
- Daphnia magna
- Details on test organisms:
- Young daphnids (6-24 hours old) bred in the laboratories under identical temperature and light conditions as in the tests. The cultivation is performed in reconstituted water of identical quality as the water used in the tests.

- Details on results:
- The degradation product of the test item has no toxic effect on the daphnids up to a nominal concentration of 100 mg/l. After the 24-hr stirring period the mean concentration of FBA in the test medium corresponded to a FBC concentration of 99 mg/l, demonstrating the complete transformation of the test item to its breakdown product within the 24-hr stirring period. At the end of the test the FBA concentration corresponded to 84 mg FBC/l. Based on the measured concentration of FBA at the start and the end of the incubation period the concentrations ranged from 99 to 84% of the nominal concentration. The resuls are based on the nominal concentrations.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- It was shown that the breakdown product of 2-fluoro benzoyl chloride has no toxic effect on daphnids up to a concentration of nominal 100 mg FBC/l.
