Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

Few long-term toxicity tests have been carried out to study the toxicity of tetrachloroethylene to fish of which the outcomes are in the same order of magnitude.

Poecilia sphenops appears to be the most sensitive species with a 60 -day LOEC of 1.6 mg/l (Loekleet al., 1991). This study is not considered to be valid because no measures appear to have been taken to monitor concentrations or to minimise evaporation of tetrachloroethylene from the test solution; the resultant effect concentrations are based on nominal concentrations. The next most sensitive species appears to be Jordanella floridae with a 10-day NOEC of 1.99 mg/l based upon hatching success and 10-d survival of fry (Smith et al., 1991). These results are considered to be valid as test conditions are fully reported and the effect concentrations are based upon measured levels. A third study is cited in a publication by Walbridge with in sufficient information to allow a reliable assessment of this study (secondary source).
