Description of key information
An appropriate and sensitive bioassay for organic volatile compound was conducted on Chlamydomonas reinhardtii (72 h, static). An EC50 of 9.12 mg/L was determined.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 9.12 mg/L
- EC10 or NOEC for freshwater algae:
- 3.94 mg/L
Additional information
Two studies were selected to assess the toxicity of 1,1-dichloroethylene on aquatic algae.
The study of Brack and Rottler (1994) was conducted on freshwater living species Chlamydomonas reinhardtii, with an exposure duration of 72 h in a static test system. The results are well documented and scientifically acceptable: EC50of 9.12 mg/L and EC10of 3.94 mg/L.
The study of Geyer et al. (1985) was conducted on freshwater living species Scenedesmus subspicatus with an exposure duration of 96 h and resulted in an EC50of 410 mg/L and an EC10of 240 mg/L. However, the test system is not appropriate for volatile compound and reported values are probably higher than the real one.
