Description of key information

Short-term toxicity to aquatic invertebrates

The toxic effect of the test item to Daphnia magna was assessed in a static concentration-response test. The 48-hour LOEC was determined to be 0.91 mg hydroiodic acid/L and the 48-hour EC50 value was calculated to be 1.01 mg hydroiodic acid/L.

Toxicity to aquatic algae

The influence of the test item on the growth of the freshwater green algae Pseudokirchneriella subcapitata was assessed in a static concentration-response. The 72-hour EyC50 was calculated to be 0.462 mg Hydroiodic acid/L and the 72-hour ErC50 value was calculated to be 1.58 mg Hydroiodic acid/L. The 72-hour NOEyC was determined to be 0.029 mg Hydroiodic acid/L and the associated 72-hour LOEyC was 0.093 mg Hydroiodic acid/L. The 72-hour NOErC was determined to be 0.093 mg Hydroiodic acid/L and the associated 72-hour LOErC was 0.298 mg Hydroiodic acid/L.
