- -
- EC Number:
- 425-220-8
- EC Name:
- -
- Cas Number:

Constituent 1
Sampling and analysis
- Analytical monitoring:
- yes
- Details on sampling:
- Analysis of duplicate samples of the BDP in water after the 48-hour test period found concentrations of 1.03 and 1.06 mg/L, which was around 105% of the nominal concentration. Four replicate tests were conducted using ten Daphnia in each test vessel, together with a solvent control, using ten test animals.
Test solutions
- Vehicle:
- yes
- Details on test solutions:
- The test substance was firstly dissolved in dimethylformamide to produce a 10 g/L solution. An aliquot of this was added to the test vessels in order to produce the indicated nominal concentrations.
Test organisms
- Test organisms (species):
- Daphnia magna
Study design
- Test type:
- static
- Water media type:
- freshwater
- Limit test:
- yes
- Total exposure duration:
- 48 h
Test conditions
- Hardness:
- around 100 mg/L as CaCO3
- Test temperature:
- controlled at 21± 1°C
- pH:
- always between 7.9 and 8.1
- Dissolved oxygen:
- between 7.7 and 8.2 mg/L
- Nominal and measured concentrations:
- Analysis of duplicate samples of the BDP in water after the 48-hour test period found concentration of 1.03 and 1.06 mg/L, which was around 105% of the nominal concentration.

- Effect conc.:
- > 1 mg/L
- Nominal / measured:
- nominal
- Details on results:
- No immobilisation of any of the 40 test Daphnia was observed during the course of the test, nor was any other aberrant behaviour observed. These results indicate that the BDP is not toxic to this species up to the limits of its water solubility.
Any other information on results incl. tables
These results indicate that the BDP is not toxic to this species up to the limits of its water solubility.
Applicant's summary and conclusion
- Conclusions:
- These results indicate that BDP is not toxic to this species up to the limits of its water solubility.
