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.
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.
