Additional information
Conclusion on classification
Environmental classification based on Acute and Chronic studies performed for three trophic levels of freshwater species is :
Acute 1 (H400) - No M-Factor applicable (lowest Acute EC/LC50 is the 48 hour EC50 for Daphnia, 0.38 mg/L).
Chronic 1 (H410) - Adequate Chronic toxicity data available, substance Non-Rapidly Biodegradable, lowest long-term NOEC is 0.031 mg/L (Daphnia Reproduction study).
