Description of key information

Short-term toxicity to fish

Exposure of rainbow trout to the test item gave LL50 values of greater than 100 mg/L loading rate WAF. The No Observed Effect Loading Rate was 100 mg/L loading rate WAF (OECD 203 and EU Method C.1).

Short-term toxicity to aquatic invertebrates

Exposure of Daphnia magna to the test item gave EL50 values of greater than 100 mg/L loading rate WAF. The No Observed Effect Loading Rate was 100 mg/L loading rate WAF.It was considered unnecessary and unrealistic to test at concentrations in excess of 100 mg/L (OECD 202 and EU Method C.2).

Toxicity to aquatic algae and cyanobacteria

Exposure of Pseudokirchneriella subcapitatato the test item gave EL50 values of greater than 100 mg/L loading rate WAF. The No Observed Effect Loading Rate was 100 mg/L loading rate WAF (OECD 201 and EU Method C.3).

Toxicity to microorganisms

The effect of the test item on the respiration of activated sewage sludge microorganisms gave a 3-hour EC50 value of > 1000 mg/L. The Observed No Effect Concentration (NOEC) after 3 hours exposure was 1000 mg/L (OECD 209).
