Description of key information
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 259 mg/L
- EC10 or NOEC for freshwater algae:
- 130 mg/L
Additional information
The toxicity to algal growth was determined in GLP-compliant, static, freshwater tests following OECD guideline 201. In this study, the chemical confirmation of the test substance was based on analysis of the the total organic carbon (TOC). Nominal loading rates were 0 (control), 65, 108, 180, 300 and 500 mg/L. The geometric mean concentrations were 63, 101, 162, 285 and 493 mg/L. Based on growth rate the 72 h NOEC was 130 mg/L and the ErC50 was 259 (253 - 265) mg/L for dilithium glutarate.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
