Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Clarke (2012) reports a 3-hr EC50 for toxicity to microorganisms of 80 mg/L and a 3-hr NOEC of 32 mg/L.

Key value for chemical safety assessment

EC50 for microorganisms:
80 mg/L
EC10 or NOEC for microorganisms:
32 mg/L

Additional information

A reliable toxicity study with microorganisms is available for KEL3587 and is included in this dossier.

 

Clarke (2012) conducted a reliable (Klimisch 1) GLP compliant study following OECD 209 methods withKEL3587. A mixed population of activated sewage sludge micro-organisms was obtained from a sewage treatment plant. Organisms were exposed concentrations of 18, 32, 56, 100 and 180 mg/L in a static test for 3 hours. The effect of the test item on the respiration of activated sewage sludge micro-organisms gave a 3-Hour EC50 value of 80 mg/L, 95% confidence limits 72 - 89 mg/L, based on oxygen consumption. The NOEC after 3 hours exposure was 32 mg/L.

               

A reliable toxicity study with microorganisms is available for KEL3587 and is included in this dossier. Clarke (2012) reports a 3-hr EC50 for toxicity to microorganisms of 80 mg/L and a 3-hr NOEC of 32 mg/L. Consequently these values will be taken as the toxicity in microorganisms endpoint for KEL3587.
