Validity criteria fulfilled:
not specified
Conclusions:
The 96-h LC50 of ATLOX 3300 B (Benzenesulfonic acid, dodecyl-, compd. with 2-propanamine (1:1) ) to rainbow trout was 6.8 mg/L.
Executive summary:

The acute toxicity to rainbow trout of ATLOX 3300 B (Benzenesulfonic acid, dodecyl-, compd. with 2-propanamine (1:1) ) was tested in a 96 h aerated static test at 15 ± 1°C. The 96-h LC50 was 6.8 mg/L.
