Aluminium potassium bis(sulphate)

Toxicity to microorganisms

Description of key information

The supporting study from Abraham et al gave an estimated EC50-2h for Aspidisca cicada and Vorticella convallaria
of 14.56 mg  and 17.15 mg dissolved AlK(SO4)2/ kg as dry weight.
The key study from Chowdhury et al. gave an estimated EC50-4h for Vibrio species of 630 mg/L as total
aluminium potassium bis sulphate.
Based on the Key -and supporting study of toxicity to microorganisms 
the calculated EC50 for aluminium potassium bis sulphate is 630 mg/L.
