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

Constituent 1
Sampling and analysis
- Analytical monitoring:
- yes
- Details on sampling:
- A Static Limit Test (no replacement of test water) was performed over 96 hours using a solution of the test substance made up at a nominal concentrationof 1 mg/L in charcoal filtered dechlorinated tap water. The test was performed in duplicate using ten fish in each test vessel. A solvent control was also run in parallel, also using ten fish.
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):
- Oncorhynchus mykiss (previous name: Salmo gairdneri)
Study design
- Test type:
- static
- Water media type:
- freshwater
- Limit test:
- yes
- Total exposure duration:
- 96 h
Test conditions
- Hardness:
- around 100 mg/L as CaCO3
- Test temperature:
- controlled at 14 ± 1 °C
- pH:
- always between 7.7 and 8.0
- Dissolved oxygen:
- between 9.4 and 10.1 mg/L
- Nominal and measured concentrations:
- It is to be noted that the nominal concentration of 1.0 mg/L for the test chemical was greater than the measured water solubility (0.4 mg/L), and in order to attain this nominal concentration, 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.However, analysis of samples of the test solutions taken at 0, 24 and 96 hours indicated up to 115% recovery of the test compound. Presumably the presence of the dimethylformamide in the water helped maintain this high solution concentration. It was noted in the report that during work on the initial range finding study test material precipitated out of solution at concentrations in excess of 1.0 mg/ L.

Any other information on results incl. tables
- Sublethal observations / clinical signs:
All test specimens survived over the 96-hour test period. Further, no physical or behavioural anomalies were observed during the test period, and accordingly which it was concluded that the BDP is non toxic to rainbow trout up to the limits of its water solubility.
