Applicant's summary and conclusion

Validity criteria fulfilled:
yes
Conclusions:
No bioconcentration of radioactivity occured and no effect on the fish was observed. Most of the data points were within the normal variability of background radioactivity levels.
Executive summary:

Bluegill sunfish were exposed to 0.5 mg/L of test substance for four weeks in a dynamic study designed to measure the accumulation and distribution of 14C-residues in edible tissue, viscera, remaining carcass and whole fish. A two-week depuration phase followed the exposure phase. No bioconcentration of radioactivity occurred and no effect on the fish vas observed. Most of the data points were within the normal variability of background radioactivity levels.
