Description of key information

The  lowest reliable short-term toxicity to terrestrial plants  (Triticum aestivum) which is reported by Pettersson, S., Strid, H.1989 after a 9 days exposure to aluminium sulphate was 542 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 terrestrial plants (Picea abies) which is reported by Henriksen, T.M., T.D. Eldhuset, A.O. Stuanes, and B.R. Langerud 1992, after a 105 days exposure to aluminium sulphate was 127 mg/kg soil dw (NOEL).
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 or LC50 for terrestrial plants:
542 mg/kg soil dw
Long-term EC10, LC10 or NOEC for terrestrial plants:
127 mg/kg soil dw

Additional information

Under the conditions of the study of Pettersson, S., Strid, H.1989, aluminium sulphate induced No Growth effects in Triticum aestivum below 108.3 mg/kg soil (NOEC). One of the 9d-EC50 was 542 mg/kg soil.

 

Under the conditions of the study of Henriksen, T.M., T.D. Eldhuset, A.O. Stuanes, and B.R. Langerud 1992, of aluminium sulphate induced no Accumulation effects in Picea abies below 127 mg/kg soil (NOEL).
