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.

Key value for chemical safety assessment

BCF (aquatic species):
49

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.
