Materials and methods
- Principles of method if other than guideline:
- Toxicity test according to Bobra et al. (1983), Chemosphere 12, 1137-1149.
- GLP compliance:
- no
Test material
- Reference substance name:
- Chloroform
- EC Number:
- 200-663-8
- EC Name:
- Chloroform
- Cas Number:
- 67-66-3
- Molecular formula:
- CHCl3
- IUPAC Name:
- chloroform
- Test material form:
- liquid
Constituent 1
Sampling and analysis
- Analytical monitoring:
- no
Test solutions
- Vehicle:
- no
- Details on test solutions:
- Saturated aqueous solutions of chloroform were prepared and diluted to provide at least 5 exposure concentrations plus a control. Test chambers were filled and sealed in glass vials with teflon-lined screw caps. Air spaces in exposure chambers were eliminated to minimise volatilisation loss of the toxicant from water.
Test organisms
- Test organisms (species):
- Daphnia magna
- Details on test organisms:
- 4 to 6 day old Daphnia from laboratory-breeded stocks were used for the test.
Study design
- Test type:
- static
- Water media type:
- freshwater
- Limit test:
- no
- Total exposure duration:
- 48 h
Test conditions
- Test temperature:
- 23 +/- 2 °C
- Dissolved oxygen:
- Concentration was typically at 8 to 9 mg/L and after 48 hours, the lowest measured concentration was 5 mg/L.
Results and discussion
Effect concentrations
- Duration:
- 48 h
- Dose descriptor:
- LC50
- Effect conc.:
- 79 mg/L
- Nominal / measured:
- nominal
- Basis for effect:
- mortality
Applicant's summary and conclusion
- Executive summary:
The acute toxicity of chloroform to 4 to 6 day old Daphnia magna was tested in a static test with sealed vessels. The endpoint for the toxicity assessment was mortality. The LC50 value determined was 79 mg/L.
