Description of key information
The lowest reliable short-term toxicity to soil microorganisms (Eisenia fetida) which is reported by of Phillips, D.R., and T. Bolger 1998, after a 30 days exposure to aluminium sulphate was 2000 mg/kg soil dw (EC50).
This information will be take into account for terrestrial plants toxicity for the derivation of PNEC.
The lowest reliable long-term toxicity to soil microorganisms (Eisenia fetida) which is reported by Cornelis A.M. van Gestel and Gert Hoogerwerf 2000, after a 42 days exposure to aluminium sulphate was 579 mg/kg soil dw (NOEC). One of the 42d LC50 was 2893 mg/kg soil dw.
This information will be take into account for terrestrial plants toxicity for the derivation of PNEC.
Key value for chemical safety assessment
- Short-term EC50 for soil microorganisms:
- 2 000 mg/kg soil dw
- Long-term EC10 or NOEC for soil microorganisms:
- 579 mg/kg soil dw
Additional information
Under the conditions of the study of Phillips, D.R., and T. Bolger 1998, aluminium sulphate induced No Mortality effects in Eisenia fetida below 400 mg/kg soil (NOEC) at pH 4.2. One of the 30d LC50 was between 2000 and 4000 mg/kg soil dw.
Under the conditions of the study of Cornelis A.M. van Gestel and Gert Hoogerwerf 2000, aluminium sulphate induced No Mortality effects in Eisenia andrei below 579 mg/kg soil (NOEC) . One of the 42d LC50 was 10 and 2893 mg/kg soil dw.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
