Description of key information

In a 48h acute toxicity study Daphnia magna were exposed to SPS-100. Toxic levels were above the maximum water solubility of SPS-100. Therefore, it was concluded that no acute toxicity was observed up to the solubility limit. The study is considered to bereliable without restrictions according to OECD Guideline No. 202.

Key value for chemical safety assessment

Additional information

In a 48-h acute toxicity study, water fleas (Daphnia magna) were exposed to the substance at nominal concentrations of 0 (blank-control), 0.1% (filtrate), 1% (filtrate), 10% (filtrate), 100% (filtrate) and 100 mg/L (unfiltered) under static conditions. The test substance was not toxic for Daphnia magna. No toxicity was observed at any of the test concentrations, including the maximum solubility of the substance in test medium. Therefore, it was concluded that the test substance it is not acutely toxic up to the solubility limit. The study is considered to be reliable without restrictions according to OECD Guideline No. 202.
