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.
