Materials and methods

Qualifier:
according to
Guideline:
OECD Guideline 202 (Daphnia sp. Acute Immobilisation Test)
GLP compliance:

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.

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

Validity criteria fulfilled:
yes
Remarks:
An OECD guideline test by peer reviewed
Conclusions:
These results indicate that BDP is not toxic to this species up to the limits of its water solubility.
