Additional information

Environmental Classification related key information for H250 Sulphonic acid:

Biodegradation in water: readily biodegradable (RA from LABS)

Bioaccumulation: no potential to bioaccumulate; BCF= 87 and 102.8 -313.3 L/kg (RA from LABS and EPISUITE QSAR calculation, respectively)

Water solubility: miscible (RA from LABS and EPISUITE QSAR calculation)

The Summary of Acute aquatic toxicity data for H250 Sulphonic acid:

For fish: 96hLC50> 1.67 mg/L (RA from LABS)     

For invertebrates: 48h EC50 = 2.9 mg/L (RA from LABS Na)      

For algae: 72h-EbC50 = 127.9 mg/L (RA from LABS Na)          

The Summary of Chronic aquatic toxicity data for H250 Sulphonic acid:

For fish: 72d NOEC = 0.23 mg / L (RA from LABS Na)     

For invertebrates: 21d NOEC= 1.18 mg /L (RA from LABS Na)

For algae: 72h-NOECb ≥ 2.4 mg/L (RA from LABS Na)        

Conclusion on classification

Based on chronic aquatic data from analogue substance, H250 Sulphonic acid should be classified as category aquatic chronic 3 according to EU CLP Regulation.
