Description of key information
The toxicity of HDI trimer to algae (Desmodesmus subspicatus) was assessed performing a study according to the German standard: DIN 38 412, Part 9 (1989) "Zellvermehrungshemmtest: Scenedesmus subspicatus CHODAT (Grünalge)", which is in most parts equivalent to the OECD TG 201. The 72h-EC10 was 370 mg/L. The EC50 was > 1000 mg/L.
In a supporting study the toxicity of HDI trimer to algae (Desmodesmus subspicatus) was assessed performing a study according to the Directive 92/69/EEC, C.3: Algal inhibition test, which is in most parts equivalent to the OECD TG 201. No inhibition of the algal population as reduction in growth rate was observed after 72 h at a test concentration of 100 mg/L. The results are expressed in terms of nominal concentrations.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 1 000 mg/L
- EC10 or NOEC for freshwater algae:
- 370 mg/L
Additional information
The key value for acute toxicity should read >= 1000 mg/L but "<=" may not be selected.
