Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

Bluegill Lepomis macrochirus (a freshwater fish) was exposed to 3.43 μg/l tetrachloroethylene for 21 days at 16°C in a closed, flow-through system. The concentration of tetrachloroethylene (as 14C-label) was monitored to steady state in water and fish. The bioconcentration factor (BCF) was 49 and the half-life in tissue was less than 1 day.

Additional information

Bioaccumulation does not appear to occur to a significant extent. Several studies measured the whole body bioaccumulation factors measured for fish, the values ranged from 49 to 77.1. Also studies with algae were available. The flow through study with concentration monitoring, which is highly similar to OECD guideline 305 (Barrows, 1980), is taken as the key study.
