Additional information
Conclusion on classification
Conclusive experimental results are available from acute tests for fish, invertebrates (daphnia), algae and microorganism.
Short-term toxicity to fish:
96-h-LC50: > 100 mg/L (nominal, WAF)
Short-term toxicity to aquatic invertebrates:
48h-EC50: > 100 mg/L (nominal, WAF)
Toxicity to aquatic algae and cyanobacteria:
72h-EC50 of > 100 mg/L (grow, nominal, WAF)
72h-NOEC of ≥100 mg/L (grow, nominal, WAF)
Toxicity to microorganisms:
3h-NOEC: > 1000 mg/L
Evaluation is based on classification categories for hazardous to the aquatic environment according to GHS Regulation EC No 1272/2008.
EC50/LC50 values obtained from acute tests for the three trophic levels are all above 100 mg/L.
Therefore no classification neither for acute nor for chronic aquatic hazard is required for Phosphoric acid, C12-18-alkyl esters, potassium salts.
